The thickness of the diffusion layer reckoned by computation of steady-state diffusion equation has been found in agreement with the results obtained through laboratory experiment.
稳态蠕变速率主要由锌的点阵扩散和位错的攀移所控制,品界滑移对蠕变也有贡献。
The compressive creep rate in the alloy was mainly controlled by the lattice diffusion of zinc and dislocation limb, and the grain boundary sliding contributed for it in some degree.
