Welcome to the Sustainable Materials and Processing department.

Our department carries out research and development into new materials and their processing methods. Underpinning this is the belief that modern, application-specific materials, combined with innovative processing methods, have the potential to make our society’s technologies sustainable. In our research and development, we always follow what are known as the ‘R-strategies’. In this way, we reduce the amount of material required and the energy consumed in processes, design products so that they can be recovered or recycled, or investigate ways of recovering secondary materials that are simple and tailored to the specific material. The research projects currently underway focus on steels, aluminium materials and metal matrix composites. To ensure comprehensive adaptation – that is, adaptation which takes into account material properties across different scales and under various application and processing conditions – we utilise not only analytical, characterisation and testing methods but also tools for materials and process simulation.

Under the tabs shown above, you will find more detailed information on our current and past projects, as well as our department’s publications.

Do you have any further questions, or is there anything we can do to help you with your work? If so, please feel free to contact us using the telephone number or email address below.

We look forward to a Let’s work together!

Motivation & Objectives
The aim is to develop an electrically driven refrigerant compressor (eKMV) with increased energy efficiency, reduced weight and improved resource efficiency. To this end, a novel 9-kW compressor is being designed which, thanks to design simplifications, offers more cost-effective manufacturing and increased operational reliability. To extend the operating range and improve thermodynamic efficiency, a medium-pressure feed is being integrated into the compression process. This involves introducing refrigerant at an additional pressure level, thereby reducing the final compression temperature and increasing process stability. Another key focus of development is the replacement of conventional grey cast iron components with SiC-particle-reinforced aluminium matrix composites (AMC) for the cylinder housing.
As part of the collaborative project, a functional prototype and a technically optimised eKMV with integrated medium-pressure injection are being developed and tested. In addition, fundamental issues relating to materials and process development are being investigated. Furthermore, the reintroduction of machining swarf into the initial forming process is being investigated in order to develop recycling strategies for AMC materials and to assess their impact on the mechanical properties of the components. In addition, a sustainability assessment is being carried out using a cradle-to-cradle analysis.

Motivation & Objectives
As part of the project, atomisation processes are being utilised in collaboration with industry and research partners to produce highly particle-reinforced aluminium matrix composite (AMC) powders and to process these into near-net-shape components using the LPBF process. The aim is to establish a systematic correlation between the feedstock, the atomisation process, the LPBF process parameters and the performance characteristics of the manufactured components. In addition, cost-effectiveness and component quality are being investigated in comparison with conventional casting processes.

By the end of the project, the scientific and technical foundations should be in place to manufacture high-quality AMC products and establish them on the market. The commercial project partners expect the development of new materials and products to expand their product portfolios.

Funding is provided from the European Regional Development Fund (ERDF) and from tax revenue, in accordance with the budget approved by the Saxon State Parliament.

Motivation & Objectives
The aim is to develop a recycling technology for aluminium that produces material of a quality suitable for wire drawing processes, ultrasonic metal welding (USMW) and use in electrical components. USMW is an innovative joining process that is particularly relevant for applications in electromobility, as it enables high-strength, material-bonded and electrically conductive joints without the need for filler materials. A key application lies in wiring harness connections for electric and hydrogen-powered vehicles. Aluminium enables a weight reduction of up to 40 per cent in cable harnesses, thereby contributing to a reduction in energy consumption and, indirectly, in CO₂ emissions. Furthermore, aluminium offers greater availability and lower material costs compared with copper.
At present, primary aluminium is predominantly used for electrical applications, as there is a lack of suitable recycling technologies for secondary aluminium wires with the required electrical properties. However, the development of such a technology is crucial to the sustainability of the energy transition. The use of recycled aluminium reduces greenhouse gas emissions, lowers the energy required to source the material and minimises the demand for primary raw materials such as bauxite. At the same time, it conserves natural resources and reduces the environmental impact of raw material extraction.
Furthermore, the expansion of relevant recycling technologies offers economic potential through lower production costs and the strengthening of regional value chains. The project is therefore in line with the Free State of Saxony’s innovation strategy and the Raw Materials Initiative of the Saxon State Ministry for Economic Affairs, Labour and Transport, in particular with the aim of establishing Saxony as a centre for secondary raw materials.

Duration: 2024–2026

Project partners: Chair of Materials Science, University of Paderborn
Motivation & Objectives
Particle-reinforced aluminium matrix composites (AMC) offer great potential for a wide range of applications, which is currently limited by material and manufacturing constraints. Large-scale applications require robust, reproducible and continuous manufacturing processes, which are made possible by new continuous AMC casting processes. At the same time, material quality is compromised by process-induced inhomogeneities. Conventional melt-metallurgical AMC manufacturing processes use aluminium casting alloys as the matrix material. Consequently, AMC materials have so far been available mainly as simple semi-finished products or ingots. Strip-shaped semi-finished products for forming processes or sheet metal applications do not yet exist, but would significantly expand the range of applications. The two-roll casting process combines melt-metallurgical primary forming with thermomechanical forming, and enables the production of strip-shaped semi-finished products with a reduced proportion of material inhomogeneities.
The aim of the research project is to establish correlations between process, microstructure and properties, so that different AMC material states can be taken into account in numerical process design. To this end, targeted characterisation methods are being employed to analyse material-process interactions and, building on this, to further develop material modelling and simulation. To this end, the AMC matrix materials previously used in the project—cast aluminium alloys (AlSi7Mg, AlSi9Mg)—are being replaced by heat-treatable wrought alloys. In addition to material development and process design, a comprehensive characterisation of the process steps – stir casting, casting rolling, hot rolling and deep drawing – is being carried out, including the necessary heat treatments. This enables numerical predictions to be made regarding forming forces, material flow, microstructure development and damage mechanisms.

Motivation & Objectives
Research is being conducted into a thermomechanical treatment (TMB) for sheets made of martensitic stainless steels (MNS) with minimal austenitisation times. The aim is to develop a short-duration TMB for efficient sheet hardening, which enables high degrees of forming with short process times and ensures the desired material properties. This offers potential for reducing energy consumption and improving material yield.
Rapid heating followed by quenching creates thermodynamic states of disequilibrium which influence the solubility of accompanying and alloying elements, as well as the phase transformation temperatures. Established TMB models for MNS are therefore not directly applicable to short-term processes. In this project, X46Cr13 steel is heated into the austenite region using inductive rapid heating at heating rates of at least 100 K/s, formed without a holding time, and subsequently quenched. In this process, forming steps in the stable and metastable austenite regions are investigated. Short-term TMB is carried out using a forming simulator and a forming dilatometer to analyse phase transformation and forming behaviour. The influence of heating rate and austenitisation temperature on the solution state of the alloying elements is investigated on the basis of the precipitation state and the residual austenite content using SEM, EDX, XRD and thermophysical calculations. Supplementary mechanical and chemical characterisations are used to identify a process window that both enhances the formability of the MNS sheets and ensures defined application properties at room temperature.
In the final phase of the project, a demonstration tool and a demonstration process for the production of thermomechanically treated deep-drawn parts using inductive rapid heating will be developed and tested in order to demonstrate the technological added value compared with the current state of the art.

Development of process-structure-property relationships for aluminium matrix composites suitable for the new sintering process

Duration: 2020–2023

Project partners: Chair of Welding Technology – Chemnitz University of Technology, Dr Fritsch Special-Purpose Machinery Ltd
Motivation & Objectives
The technical approach pursued in the project is the cost-effective and reproducible sintering of powdered materials in mixed and defined configurations. To this end, a hot press is being developed which enables pressure and current pulsing to be carried out during the sintering process. The aim is to break down surface oxides by using alternating current to heat the components conductively. With the aid of innovative, purpose-built and synchronised measurement technology, the entire sintering process can be monitored and analysed. On this basis, a sintering and quality criterion is being developed which makes it possible to characterise the bonding state and achieve non-destructive component monitoring. At the same time, the sintering or joining time parameter is to be based on the actual bonding characteristics that develop, rather than on empirical values. This reduces the scrap rate (caused by a sintering time set too short, resulting in incomplete or insufficient bonding) whilst also allowing the sintering time to be shortened, as the sintering process can be completed once full bonding has been achieved.
The project is being carried out in collaboration with an established plant manufacturer and service provider whose core expertise lies in application- and component-oriented plant development for sintering processes, whilst the expertise in joining technology and metrology of the Chair of Welding Technology will be utilised. The area of materials characterisation and analysis for verifying the targeted material quality characteristics is covered by the Chair of Materials and Surface Engineering.

Motivation & Objectives
The research project aims to reduce traffic-related particulate emissions by developing low-wear braking systems for passenger cars. Conventional cast-iron brake discs are subject to significant wear and thus contribute substantially to particulate emissions from road traffic.
Particle-reinforced aluminium matrix composites (AMCs) are being investigated as alternative materials for brake discs in order to minimise wear. However, the large-scale industrial application of these materials is currently limited by a lack of understanding of tribological interactions and the absence of suitable processes for function-oriented finishing. The aim of the project is therefore to develop a fundamental understanding of the relationships between surface characteristics, pre-conditioning and wear behaviour of AMC-based braking systems under application-relevant loads. The focus is on the brake disc/brake pad tribological system.
A key area of research is the development of manufacturing strategies for producing functional friction surfaces. The research focuses on surface structures that enable the controlled formation of the tribofilm and optimised running-in behaviour. Two approaches are being pursued to this end: the targeted removal of the matrix alloy with micrometre precision, and the creation of defined micro-edges through ultrasonic-assisted machining. The resulting surfaces are characterised using optical, tactile and microstructural resolution techniques. The findings obtained on a laboratory scale are transferred to real brake discs and validated in collaboration with the application partner. The project combines materials science and manufacturing engineering approaches to form an interdisciplinary concept for low-emission braking systems.

Motivation & Objectives
The overarching aim of the planned project is to develop a suitable method for predicting heat treatment parameters that depend on boundary conditions and component geometry, with a view to specifically adjusting processing or service properties whilst simultaneously optimising energy consumption. The heat treatment parameters are to be predicted using artificial neural networks (ANNs) based on the component geometry and batch composition. This will eliminate the need for time-consuming preliminary trials to achieve the desired heat treatment result, thereby enabling more cost-effective and energy-efficient production. To this end, a database-driven prediction tool is being developed and validated; this will be made available to all interested users and will significantly reduce the need for costly and time-consuming ‘trial-and-error’ tests that would otherwise be required for every new variation in geometry and batch composition. This tool is structured in two stages and performs the following functions:
1) Reliable prediction of the heat treatment cycle and heat treatment results (properties) for various components (shafts) in heterogeneous batches, depending on the material, for given heat treatment parameters (time, temperature).
2) Based on this, inverse optimisation is used to determine the energetically and technically optimised settings for the heat treatment parameters in order to achieve the required component properties (hardness). The optimisation of the heat treatment parameters is carried out whilst ensuring minimum energy consumption.

Motivation & Objectives
In the proposed transfer project, a direct casting process for AMC materials – previously developed as part of a publicly funded project – was scaled up from the demonstration stage to industrial applicability. By the end of the funding period, a casting line suitable for small and special production runs was in place, on which AMC semi-finished products can be produced reproducibly for further processing in accordance with application-specific material specifications. At the same time, further commercialisation was achieved through the spin-off of a start-up, CMMC GmbH (https://www.cmmc-engineering.com/). The products include both materials and semi-finished products in single and small batches, as well as the process itself and its licensed use. Users of AMC semi-finished products, AMC products and AMC raw materials – and thus potential interested parties – were already identified during the course of the funded project and involved in the development work.

Motivation & Objectives
The project focuses on investigating the adhesion mechanisms and characterising the adhesion criteria of DLC coatings deposited by PACVD onto plasma-nitrided steel surfaces. A fundamental and systematic approach was adopted to enable the evaluation of the identified adhesion criteria. The aim of the work was to develop a knowledge-based model of the adhesion of DLC coatings to plasma-nitrided steels, which would allow for application-specific conclusions, for example with regard to maximising adhesion. The starting point was the observation that, compared with untreated steels, DLC coatings on plasma-nitrided steel surfaces exhibit very high adhesion values even without metallic intermediate or bonding layers. At the same time, it is possible to achieve different chemical, structural and morphological modifications of the treated steel surface by varying the plasma nitriding parameters.

Project partners: Fraunhofer IWU Chemnitz
Motivation & Objectives
Thermally sprayed coatings are used in mechanical and plant engineering, as well as in tool and mould making. The required performance characteristics are often linked to the fine surface finish of the components. For example, surfaces in tribological systems often require defined oil retention volumes to ensure dry-running properties. The finishing process therefore influences the tribology of sliding systems, the resulting component wear, thermal effects during component operation, the properties of interacting material surfaces and much more. It must therefore, on the one hand, be adapted to the intended application and, on the other hand, lead to reproducible results in terms of the geometric and material properties of the surface.
As part of a research project, open-pored thermally sprayed coatings were gas-nitrided and subsequently machined to achieve a specific and robustly reproducible surface condition. The machining targets relate equally to the microscale surface topography – i.e. roughness and surface-open porosity – and to the microstructural and chemical state of the near-surface boundary zones of the machined components. The components were finally characterised functionally using experimental investigations on a tribometer.

Motivation & Objectives
The transport sector accounts for a very high proportion of primary energy consumption and critical emissions. Consequently, energy savings and emissions reductions are of great importance for sustainable mobility. Tailor-made lightweight construction solutions can create synergies that address both of these issues. The project focused on light-metal brake discs made from highly reinforced aluminium composites (AMC) and their finishing for use in high-volume vehicle production.
The aim of the proposed project was to to use a smart tool during the final machining of AMC brake discs to generate a preconditioning effect in the form of an artificially applied tribofilm on the AMC surface, resulting in a stable steady state of the tribosystem.

Project partners: Chair of Formative Shaping and Joining, Chemnitz University of Technology
Motivation & Objectives
High-alloy martensitic stainless steels (MNS) exhibit good corrosion resistance as well as high hardness and strength. Components made from these steels are currently produced largely by cold forming in the soft-annealed condition. After forming, it is necessary to achieve the desired mechanical properties through hardening and tempering. However, the degrees of forming achievable by cold forming are often insufficient for the manufacture of complex components. This disadvantage can be overcome by thermomechanical treatment (TMB), i.e. forming at elevated temperatures with precise control of the forming and temperature regimes. During TMB of martensitic stainless steels, various metal-physical processes (phase transformation, recrystallisation, precipitation) which influence both the processing properties (formability) and service properties (hardness, strength, corrosion behaviour) to an equal extent. This presents the user with fundamental challenges in terms of the interrelationships between process engineering and materials science. Consequently, the effects of thermal and thermomechanical treatment on the formability and service properties of martensitic stainless steels have so far been inadequately researched. The project therefore systematically investigated the key process parameters of thermal and thermomechanical treatment (austenitising temperature, holding time, degree of forming, forming temperature and forming rate) and their effect on the microstructures of representative grades of these steels. In this way, on the one hand, the specific boundary conditions for process control were determined. On the other hand, the metallophysical processes influenced by TMB and their impact on precipitation and transformation kinetics, as well as the resulting microstructural changes, were identified. From this, the potential of TMB processes for extended applicability to MNS was derived.
