Subproject B10

Influence of the Surface State on Quasi-static and Cyclic Deformation and Damage Behavior of TRIP/TWIP Steels

The goal of this project is to investigate the influence of the surface state on the mechanical behavior of austenitic high-alloyed TRIP/TWIP steels of the Mn-Al-Si concept. For this, specific surface morphologies manufactured by micro and macro machining within the CRC 926 will be characterized by microscopical as well as x-ray methods. Their influence on the quasi-static and cyclic properties will be evaluated by in situ-mechanical testing in the SEM as well as by fatigue tests with subsequent ex situ analysis of the near-surface microstructure. Later, first prototypes for high performance and wear resistant chain pins will be manufactured and tested.
