| 摘 要： | 用金相显微镜和X射线衍射研究了强磁场条件下Al-8％Ni合金中非铁磁性的Al3Ni析出相的凝固行为，发现强磁场诱导Al3Ni晶粒以C轴平行磁场方向取向，并且晶粒的长轴与C轴垂直；取向的晶粒在垂直磁场方向上形成多个相互平行的Al3Ni聚合面，即形成规则的Al3Ni层状组织：在层状聚合面中随机分布着多个大的Al3Ni聚合体，聚合体内部的晶粒有序排列。

| Abstract: | The solidification behaviors of nonferromagnetic Al3Ni precipitated phase in Al-8%Ni alloy with a high magnetic field applied have been studied experimentally. It is found that the magnetic field induces the crystals of Al3Ni phase to orient with their c-axes parallel to the field and the long axes of the crystals are perpendicular to their c-axes. There are several Al3Ni congregation planes parallel with each other, which are perpendicular to the field, that is, regular Al3Ni laminated alignment structure is formed in the alloy. In the planes, there are several big Al3Ni congregations, in the inner part of which there are aligned Al3Ni crystals. |
