Grain boundary diffusion plays an important role in the whole sintering course.
晶界扩散在烧结过程中始终起着非常重要的作用。
2
Diffusion of oxygen in the bonding coating and substrate is mainly grain-boundary diffusion. Grain-boundary diffusion coefficient is far greater than intragrain diffusion.
氧在粘结底层和基体中的扩散是以晶界扩散为主，晶界扩散系数远远大于晶内的扩散系数。

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.
