Analysis and modeling of the inherent stresses of high-alloyed cast steel components with regard to the highest dimensional stability requirements

This project aims the development of a model chain and experimental methods to describe the evolution of inherent stresses during the production of a housing component made of austenitic steel.

Computational research on microstructure evolution and mechanical properties of martensitic stainless steel during welding and heat treatment processes This project aims at the prediction of microstructure evolution and thermomechanical properties in and around a laser weld seam of a martensite steel plate.
ICME-based crash relevant parts of high manganese TWIP steels This project aims a precise prediction of wrinkle formation and absorbed energy in a hexagonal crash box made of a high manganese TWIP steel.
ICME-based process and alloy design for vacuum carburized steel components with high potential of reduced distortion This project aims the development of an energetic efficient production of forged components from micro alloyed dual phase steel with reduced distortion.
ICME-based process modelling and geometry prediction of hot isostatically pressed HIP near-net-shape components This project aims on investigating the influence of powder filling process and inhomogeneous initial density distribution inside the capsule on the final shape of a component. Those factors are subsequently considered to optimize the capsule design to achieve near-net-shape production with minimum distortion of hot isostatically pressed components.
Microstructure improvement during closed die forming operations by the help of Finite Element simulation combined with processing maps This project aims at the adaption of a closed die forming operation to produce a gear wheel by the help of Finite Element (FE) simulations combined with processing maps to ensure a homogenous fine grain size after forging.

Multi-Scale simulation of heat treatment of hot-work tool steels

This project aims at realistic prediction of the evolution of the microstructure, residual stresses and distortion during the entire heat treatment cycle including tempering by means of FE-modeling and simulation.

Simulation of deep and pendular grinding processes

This project aims to quantitatively predict the residual stresses after grinding processes by means of FE-modeling and simulation.
