Influence of low temperatures on the cyclic deformation and transformation behavior of metastable austenitic steels
The project involved examining the quasi-static and cyclical deformation and transformation behavior of three metastable austenitic steels: X5CrNi1810 (AISI 304), X6CrNiTi18 10 (AISI 321) and X10CrNiNb189 (AISI 348) in the temperature range -60°C ≤ T ≤ RT.

The research was carried as part of the German Research Foundation’s (DFG) Research Training Group (GRK) 814 Engineering materials on various scales: experiment, modeling and simulation.
