Abstract

In this work, the molecular dynamics simulations are used to investigate the mechanical behavior of the imprinted nickel aluminide alloys. These atomic simulations account for the mold size, working temperature, imprinting velocity and the elastic recovery. It has been found that there exists a significant difference of the shear stain distribution in the inhomogeneous plastic deformation around the mold corner, whereas obtained lower elastic recovery values in the imprinting process indicates a higher material formability. Moreover, it has been also shown that the degree of the material softening increases with temperature causing the graduate extension of the strain to the bottom of the material. And, finally, the elastic recovery of the imprinted material decreases as the imprinting velocity is increased.
