Effect of nonlinear and noncollinear transformation strain pathways in phase-field modeling of nucleation and growth during martensite transformation

Structural transformation: a less linear approach A method for modeling complex changes in the crystal structures of solids is developed by researchers in the USA. Yunzhi Wang from the Ohio State University and his colleagues’ model provides a more accurate description of crystal structure rearrange...
