Abstract Scope |
Simulation of large-scale behavior from microscale deformation are ideally based on inputs that come from the very same material one tends to simulate. The direct extraction of micromechanical properties of a single martensite variant by tensile testing have been performed. The present study reports a detailed experimental approach to extract the critical resolved shear stress (CRSS) and the saturation stress of the elementary constituent of the microstructure of quenched S41500 martensitic stainless steel by conducting different microscopy observations and micro-tensile testing. Here, a comparison of the micromechanical properties of lath martensite exhibiting slip on {110} and {112} planes is made with studies in the literature for tensile and compression testing procedures, showing excellent agreement. Finally, a minimal difference exits between the CRSS of {110}, {211} and {123} planes, in concurrence with larger scale test results in the literature. |
