Lath martensite is a complex hierarchical compound structure that forms during rapid cooling of carbon steels from the austenitic phase. At smallest, i.e., ‘single crystal’ scale, individual, elongated domains, form elemental microstructural building blocks: name-giving laths. Several laths nearly identical crystallographic orientation are grouped together to blocks, in which–depending on exact...

Numerous studies have demonstrated the widespread presence of chemical short-range order (SRO) in medium and high entropy alloys (M/HEAs). However, mechanism their influence on macroscopic mechanical behavior remains to be understood. In this paper, we propose a novel dislocation-based model crystal plasticity, by considering both dislocation blocking coplanar slip induced SRO. The effect SRO p...
