Transformation textures and stress distribution during martensitic transformation

摘要

A modeling of the evolution of austenite texture is presented in case of phase transformation in 304 AISI steel occurring during a tensile test at -60 ℃. The computed textures agree well with those measured experimentally by X-ray diffraction. X-ray diffraction also enables to analyze stress distribution in both phases of this steel. First trend shows that Martensite is in compression and austenite is in tension after unloading.
