subgrain 中文意思是什麼
subgrain
解釋
次級晶粒-
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合金在電場作用下表現出和鋁理合金類似的組織和性能的變化規律：合金的強度值升高不明顯，塑性在電場固溶和時效下有較大的提高；在斷裂特徵上表現為韌窩增加。 -
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
室溫ecap細化晶粒的機理可描述為：隨著強烈塑性變形的進行，原始晶粒中產生了很多位錯纏結和位錯胞，進而位錯胞崩塌變為亞晶或晶粒，亞晶粒在後續ecap剪應力作用下，通過亞晶界被剪斷而變為晶粒。
