Effect of crystallographic orientation on the phase transition of a finite TiNi shape memory alloy wafer.

Abstract

A simulation of a TiNi shape memory alloy plate was carried out at various crystallographic orientations using a free package for classical molecular dynamics LAMMPS. It was found that the crystallographic orientation of the plate has a significant effect on the phase transition temperature. The dependence of surface energy on temperature for crystallographic orientations (100), (110), (112), (122) was constructed. The stability of the model used was investigated, as a result of which its applicability in these calculations was confirmed.
