MD simulation of martensitic transformations in TiNi alloys with MEAM

Abstract

The martensitic transformations in TiNi alloys were studied using molecular dynamics (MD) simulations. The modified embedded atom method was used with the pseudo monoatomic potentials, which included angular dependence of each atoms. The thermally induced B2 → B19′ martensitic and B19′ → B2 reverse martensitic transformations have been obtained in the present molecular dynamics simulations with a bulk (no surface) computational model. The martensitic transformation temperature of TiNi varies very rapidly with composition in the range 35∼60 at.%Ni in the present MD simulations.
