大角度晶界 meaning in Chinese
high angle boundary
high angle grain boundary
high-angle grain boundaries
large angle boundary
Examples
- After ten passes , the average grain size of the microstructure which including high angle boundaries is about lum . the vickers hardness increases rapidly after ecap , from 78 . 7hv to 185 . 3hv
Ecap十道次时，晶粒尺寸在1 m左右，晶界为大角度晶界，硬度明显增加，显微硬度从原始态的78 . 7hv增加到185 . 3hv 。 - By pressing with four different routes for three passes , the experiments confirm that the development of microstructure of grains separated by high angle boundaries occurs more rapidly in route be , and the amplitude of microhardness is the most rapid
采用四种不同工艺路线分别进行了三道次ecap ，证实路线b _ c能更快获得大角度晶界，其硬度增幅也最大。
