Abstract The solid state reaction of Ni50Ti50 multilayer under high pressure was carried out to investigate the effect of pressure on the amorphization process. Under the pressure of 20kbars amorphization reaction could not occur at 250°C while amorphous phase formed by isothermal annealing at same temperature in vacuum as well as lower pressure. It is suggested that the effect of pressure on diffusion played a predominant role, and Ni atom should diffuse into Ti layers with vacancy mechanism rather than interstitial one.
