Abstract
- The hardness of grain boundaries with or without twinning boundaries have impact on mechanical behaviors of stainless steels. In this paper, Nanoindentation experiments were conducted by using a Triboindenter instrumented nanoindenter (Hysitron, USA), calibrated on pure aluminum and silica on the deformed stainless steel 904L and 316L, respectively. It can be seen that the hardness distributions are all random in those grains, no matter with or without twinning. Grain boundaries with twinning boundaries is higher than that without twinning boundaries for 904L SS, it should be the effect of twin boundaries existence. No obvious difference can be observed between the hardness distribution of 316L SS. The texture evolution of rolled 904L stainless steel which is austenitic phase were symmetrically at room temperature to different reductions, i.e., 0%, 20%, 40%, 60%and 80% were also researched, the result suggest a strong influence of the micromechanical incompatibility of the austenite phases on the texture evolution.
