subgrain boundary meaning in English
亚晶界
Examples
- The main elements distribution has no change and the tem results show that subgrain boundary is blurred with more dislocation . the electric fields have the same effect on ly12 alloy as to 2090 al - li alloy with enhanced ductility and more toughness socket on fracture surface
Ly12合金在电场作用下表现出和铝理合金类似的组织和性能的变化规律：合金的强度值升高不明显，塑性在电场固溶和时效下有较大的提高；在断裂特征上表现为韧窝增加。 - The refinement mechanism of grain at room temperature can be described as dislocation tangle and dislocation node form in the initial grain with severe plastic deformation , then the dislocation node form subgrains or grains . subgrains become grains by snipping of the subgrain boundaries under the action of shearing stress
室温ecap细化晶粒的机理可描述为：随着强烈塑性变形的进行，原始晶粒中产生了很多位错缠结和位错胞，进而位错胞崩塌变为亚晶或晶粒，亚晶粒在后续ecap剪应力作用下，通过亚晶界被剪断而变为晶粒。
