Abstract: Martensite has a body-centered tetragonal (bct) structure in high carbon steels. However, body-centered cubic (bcc) {112} 〈111〉-type twins instead of bct twins always be observed as the substructure of martensite in high carbon steels. In… read more here.

DOI: 10.1016/j.actamat.2020.05.019
Abstract: Abstract The low symmetry martensite phase in Nickel-Titanium (NiTi) shape memory alloy (SMA) has a hierarchical microstructure with micro-scale crystallites, which themselves consist of nano-laminates with an internal twin structure. The martensite phase deforms inelastically… read more here.

DOI: 10.2320/matertrans.mt-mj2019007
Abstract: Internal stress generated by athermal martensitic transformation from fcc (face-centered cubic) to hcp (hexagonal close-packed) was investigated in 18Cr8Ni metastable austenitic stainless steel. Lattice parameter ratio of hcp-martensite, c/a, formed by subzero treatment was evaluated… read more here.
