查询词典 dendrite

It is concluded that the diameter direction has worse macrosegregation than the catercorner direction. The strong columnar dendrite leads to positive macrosegregation. The dense crystal structure can reduce the macrosegregation of the billets.

结果表明，径向比对角线方向宏观碳偏析大；连铸坯柱状晶发达，导致中心位置附近出现较严重的碳正偏析；较致密的凝固组织有利于减轻宏观偏析；纵切面上的碳呈周期性分布。

The more the increase of cooling rate or pre-deformation, the more the secondary dendrite arms are easy to coarsen.

冷却速率越大或预变形处理以后的试样在熔化过程中更容易发生二次枝晶臂之间的合并。

Most of non-equilibrium microstructures in the original microstructure dissolve into the α-Mg matrix due to the diffusion of the solute and then the remainder is melted firstly. The more the increasing of cooling rate or pre-deformation, the more the secondary dendrite arms are easy to coarsen.

原始组织中的非平衡共晶组织在加热过程中大部分扩散溶解而溶入基体中，剩余部分在加热过程中首先熔化；冷却速率越大或预变形处理以后的试样在熔化过程中更容易发生二次枝晶臂之间的合并。
