摘要 利用Bridgman法对Zn 2 %Cu(质量分数 )包晶合金进行了快速定向凝固实验研究 ,当生长速度在 16 0 0～ 6 4 0 0 μm/s时 ,得到了类似于共晶的层片状组织。利用X射线衍射仪及透射电镜对层片状组织进行了相组成的分析 ,并结合计算亚稳相图对该组织的相及组织形成规律进行了分析 ,结果表明在快速凝固条件下Zn 2 %Cu包晶合金中实现共生生长是可能的。 Unidirectional solidification experiment on Zn-2%Cu(mass fraction) peritectic alloy was carried out by Bridgman method. Lamellar structure was obtained at a solidification velocity between 1 600 μm/s and 6 400 μm/s. The structure was investigated by XRD and TEM, combining with the calculated metastable phase diagram. The results show that it is possible to obtain coupled structure in Zn-2%Cu peritectic alloy by rapidly unidirectional solidification method.
