A combined EBSD and nanoindentation technique was applied in order to characterize the structure-property relationship of stainless steels. The austenitic phase of stainless steel undergoes fcc-bcc as well as fcc-hcp transformation, which can lead to embrittlement or to increased plasticity. The evaluation of deformation and failure mechanisms was performed on different stainless steels alloys tested in a wide temperature range, considering phase transformation and phases interaction during deformation. Based on crystallographic information, the transformation-assisted deformation mechanisms of stainless alloys were precisely described and linked to micromechanical properties (Young’s modulus, hardness) of sub-microstructural items and connected to mechanical properties of material. A model of transformation-assisted deformation in dependence of alloying, applied stresses and temperature were proposed.
