Abstract Scope |
Metastability-driven gamma to epsilon phase transformation is widely explored in the literature using a range of microscopy techniques. However, due to limited field of view in these techniques, statistical correlations between transformed volume fractions of the phases with the deformation behavior remains largely unexplored. We employed in-situ synchrotron x-ray diffraction technique to track the evolution of phase fraction, their orientation relationships, twin fraction as well as the accommodation of the dislocation density and crystallite size in the individual phases while straining the CCA sample under tensile load. In the present investigation, chemistry-engineered gamma-rich Fe38.5Mn20Co20Cr15Si5Cu1.5 CCA was studied. This presentation covers the correlations between the externally observed stages of strain hardening and the evolution of microstructural features measured by diffraction. |
