In this study, 52100 steel is subjected to different through hardening heat treatments that result in Martensite and/or Bainite as the major strengthening phase. Each heat treatment resulted in a major strengthening phase and accompanied retained austenite. The heat treated steels were subjected to tensile loading and simultaneously characterized by synchrotron X-Ray diffraction (SXRD). The SXRD results suggest that microstructural stability under mechanical load for a given heat treatment depends on characteristics of the resulted major strengthening phase including associated atomic lattice distortion and its volume fraction in the steel. The XRD results and associated load bearing micro mechanisms will be discussed.
