Yang et al. ) have used in-situ X-Ray Diffraction (XRD) technique to investigate the evolution of lattice strains in FCC and B2 phases in Fe-16Mn-10Al-5Ni-0.86C (wt.%) steel. It was shown that the pronounced strain partitioning between the softer γ and the relatively harder BCC phases leads to back stresses which further leads to enhanced strain hardening of the steel ). In the context of Fe-26Mn-16Al-5Ni-5C (at. %) steel, Wang et al. have shown that dislocation pinning by B2 precipitates leads to local strain hardening at FCC/B2 interfaces. This minimises the probability of strain localization and hence, damage initiation (during plastic deformation) at the aforementioned interfaces . It was also highlighted that pile-up of dislocations at B2 particles leads to back-stresses, further resulting in strain hardening . Similar
