摘要：

Migration of liquid films and grain boundaries in liquid phase sintered 95Mo-5Ni(wt%) alloy occurs if the sintered specimens are heat treated at temperatures above or below those of the initial sintering treatment. Behind the migrating boundaries, solid solutions in equilibrium at the heat treatment temperature are deposited on the parent grains and the process is analogous to discontinuous precipitation and diffusion induced grain boundary migration (DIGM). The coherency strain energy in a diffusion layer in the retreating grains is the driving force.
