文档介绍
,Р Based on the thickness measurement of Al and Mg atomic diffusion layer at FSpW interface the atomic diffusion coefficient atР ,Р the interface is obtained based on Fick’s law. By comparison it is found that the atomic diffusion coefficient calculated by theР established model has the same order of magnitude with that is obtained by analytical calculation.Р Р Keywords dynamic recrystallization atomic diffusion thermal mechanical coupling dislocation vacancy
