grain boundary sliding meaning in English
晶界滑移
Examples
- The substructure near the damage position was studied by ebsp , then vonbined with the relationship among substructure grain boundary sliding grain size and material deformation compatibility the mechanics of creep damage was discussed
使用电子背散射衍射技术研究了不同损伤位置附近的亚结构形成情况，结合亚结构、晶界滑移、晶粒尺寸与材料变形协调性等材料变形特点，对蠕变损伤机理进行了探讨。 - The apparent activation volume calculated by the model is about 2500a3 , which was ten times larger than that of usual amorphous alloy and was at the same range of the amorphous polymer . the model shows the main deformation mechanism of nanocrystalline ag is grain boundary sliding , which in some extent declares the similar forms of equation with amorphous alloys . with the ananlysis to the hrem of nanocrystalline ag , the discrepancy of the apparent activation volume between the nanocrystalline ag and amorphous alloys is interpreted by the loss of atoms participating in grain boundary sliding without enough reconstruction by the movement of atoms under the low temperature
运用晶界滑移的热激活理论对压缩实验结果进行了数值拟合，拟合曲线与实验数据符合很好，得到了晶界滑移的表观激活体积(热激活基本单位体积与局域瞬态应变的乘积) ，约为2500a ~ 3 ，先当于几十个原子体积大小的瞬态变化，约为非晶合金的10倍以上，与非晶高聚物的表观激活体积相当。
