| 摘 要： | 对在微重力条件下获取的Al-In(95wt-%)偏晶合金的显微组织特征进行了分析,结果表明,在空间制取的试样的Al枝晶中,还存在着大量的In质点;并且这些质点的分布具有某种规律性,由此形成了与地基样品显微组织上的明显差异,反映出一种与重力效应相关的材料凝固特性。

| Abstract: | The microstructural feature of Al-In monotectic alloy processed under
microgravity has been investigated in comparison between space and ground-based
samples. It was found that in the space sample, there are a lot of In particles in
Al dendrite, but no more in the ground-based one. Moreover, the In particles dis-
tribute with regularity and the Al dendrite has an obvious boundary layer marked
by a string of particles. Thus, the distinction between them may reflect the chara-
cteristics of the solid/liquid interface during solidification under different gravity
conditions. |
