%X Molecular dynamics simulation of stress induced martensitic transformations in stiochoimetric NiAl has been performed via embedded-atom type potential. With the help of a tensile force,stress induced martensite with 3R structure nucleated near the lower centre; and the growth processes can be described as: butterny martensite formed initially, and transformation twins appeared coincidentally;martensites with different orientation transform and combine; martensite twins sequence existed in the finial structure. The evolution of strain has been analysed, and the nucleation mechanism of stress induced martensite has been discussed.
