枝晶偏析 [材] dendritic segregation
coring
- 高压增加了溶质原子在固溶体中的固溶度,减少了枝晶偏析。
The high pressure improves solid solubility of solute into solid solution and reduces the dendritic segregation. - 利用传统的元胞自动机方法摸拟了基于溶质扩散控制界面生长机制的枝晶演变和显微偏析。
The dendrite evolution and micro-segregation based on mechanism of solute diffusion controlling interfacial growth is simulated by cellular automaton. - 模拟结果显示这种方法可以显示出枝晶形貌和显微偏析,同时可以再现凝固过程中的再辉现象。
The simulated results show that using the method can not only reveal dendrite morphology and micro-segregation but also represent the recalescence phenomenon.
