The austenitic stainless steel X5CrNiMo17-12-2 in thickness ranging from 0.2 mm to 1.0 mm was examined in regard to the mechanical properties and microstructure. The aim was to investigate the suitability of conventional test methods for thin material down to 0.2 mm. Within these investigations, all used thicknesses were characterized by conventional tensile tests and X-ray diffraction. The results were subsequently compared with each other. The material specific vertical anisotropy r and forming limit curve showed a strong dependence on material thicknesses. The results of anisotropy pointed out different values depending on the test methods performed. In addition, the results of microstructure analysis show a decrease of grain size with lower material thickness caused by the formation of twins and probably heat treatments during the manufacturing process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
