摘　　要：通过机械球磨法混合锌、铝粉末,采用压制后真空烧结法制备了高锌铝合金。探讨了烧结温度和锌含量对高锌铝合金组织及性能的影响。研究表明:当锌质量分数为20%,粉末冶金烧结温度为410℃时,锌弥散分布在基体中,使该合金材料得到强化,硬度达到60.8 HB。Zn and Al powders were mixed by mechanical milling. The high zinc-aluminium alloy was made by pressing and sequent vacuum sintering. The influence of sintering temperature and Zn content on the microstructure and properties of high zinc-aluminium alloy was studied. The results show that when Zn content is 20% and sintering temperature is 410 ℃, Zn disperses in the matrix, then, the alloy material is strengthened, the hardness of the alloy reaches 60.8 HB.
