Abstract:

The mechanical anisotropy of cold rolled metastable austenitic steels has been studied by tensile and fatigue tests, and the results have been discussed metallographically. The levels of 20 to 25% nickel and 0.2 to 0.4% carbon were chosen, and 22% chromium-6% nickel stainless steel and pure nickel were also prepared. These materials were subjected to cold rolling, and the strength and the ductility in transverse direction were compared with those in the rolling direction. From the experiments, it was concluded that the ductility and the strength in transverse direction of cold rolled metastable austenitic steels were both superior to those in the rolling direction, probably due to the texture in the austenite phase and the characteristic distribution of stress-induced martensite plates.
