Microstructure evolution during manufacturing and processing of metallic materials

Typischer Zeit-Temperatur Verlauf bei der Verarbeitung von Stahl

This part of materials technology is a central part of the activities at the chair of Materials Technology. What are the properties of a material during manufacturing? How is the microstructure changing during processing? Which influence has the microstructure evolution on the mechanical technological properties? Which process parameters together with the processing route and the chemical composition of the material will lead to the desired product properties?

In a variety of basic and appled research projects in cooperation with our company partners, we deal with these questions, as well as the investigation of potential applications in the future.

Computer simulation of precipitation and microstructure evolution in technical materials

Since 1993, a research team works on the development of advanced simulation methods and theoretical models, which are cast into software for application to research topics within and outside the research team. The contributions are documented in numerous publications in scientific journals. The software project MatCalc is published at http://www.matcalc.at. A restricted version of MatCalc is available there for free download.

The essential methods and mechanisms, which are implemented in the software MatCalc, are diffusion and precipitation modeling, nucleation theory, interaction of precipitates with the parent microstructure, multi-component systems etc.

Microstructure - property relationship

The macroscopic properties of a material are determined by its internal structure, its so-called microstructure. On one hand, the microstructure of a material can be characterized by optical and analytical methods. On the other hand, it can be predicted by computer modeling and simulation. Important parameters of a microstructure, such as grain size, precipitate morphology, dislocation density, substructure, or segregation and recrystallization effects.

In this research focus, we deal with the relationship between microstructure and mechanical-technological properties and the possibilities for predicting properties from given microstructures.
