grain boundary

基本解释

Based on above results a model of boundary migration was given and the effect of RE on the grain boundary migration, carbon atom diffusion and precipitation was discussed.
本文以此为依据设计了稀土渗入时的晶界迁移模型，并探讨了稀土对晶界迁移及对碳原子扩散与析出机制的影响。
The individual crystal units comprising the aggregate structure where the crystalline orientation does not change. The grain boundary is where these individual crystal units meet.
构成总的结构的单个的晶体个体，而晶体的方位并没有发生变化。晶界是这些单个的晶体单位相遇的界限。
The results show that the microstructure of the cast iron without being RE modified is mostly coarse-grained austenite and network carbides at the grain boundary.
结果表明，未经稀土变质处理的铸铁组织大部分为粗晶粒奥氏体，还有分布于晶界的网状碳化物；
