摘要: Abstract A mass balance for the postulated mechanism of diffusion-induced grain boundary migration (DIGM) is presented and it shown that not completely consistent with predicted behaviour described by Balluffi Cahn (1981). Some refinements proposed are suggested, in light some recent experimental observations.
