　　本文根据Al-V、Zn-V和Al-Zn的热力学数据外推Al-Zn-V的热力学相图,考虑文献报道最新的Al-Zn-V三元实验相图,优化了Al-Zn-V体系600℃和750℃等温截面,并实验验证富Al-Zn侧的相平衡关系.Al-V、Zn-V和Al-Zn的热力学数据分别采用Gong[2]、Wu[1]和Mey[3]评估过的数据.其中,由于Wu[1]等人给出的Zn-V热力学描述中缺少HCP相(Zn固溶体),本工作对HCP相进行补充和修正,得到的与实验数据吻合较好的计算相图.对于Al-Zn-V三元系,Zheng等人[4]研究了600℃Al-Zn-V等温截面,发现在富Al角存在一个新相T相,但其晶体结构数据和热力学数据尚未有报道.
