This avenue is highly challenging due to the possibility of local chemical and strain gradients at FCC/B2 interfaces and is also presently unexplored. It is worth highlighting that in the context of metallic materials, elemental segregation largely influences cohesive strength at different microstructural interfaces such as GBs, precipitate/matrix interphase interfaces etc. . However, in the context of B2s Fe-Mn-Al-Ni-C steels, this is an unexplored avenue and shows huge potentials for future investigations.
