摘要

针对 ZA27合金在常规铸造下易出现缩松、偏析等缺陷的特点

研究了该合金的挤压铸造工艺。系统试验分析了挤压工艺参数与 ZA27合金性能之间的关系。研究表明:挤压铸造能显著提高 ZA27合金的密度和力学性能

通过工艺参数的控制

既可获得高强度（σ

达440～480 MPa

10%）

又可获得高塑性（σ

在400 MPa 左右

δ达14%～17%）的 ZA 合金。

Abstract

To reduce the tendency to produce defects

such as microporosity and segregation

in tra- ditional gravity casting

a squeeze casting ZA27 alloy process was investigated.The relation between process parameters of squeeze casting and properties of ZA27 alloy has shown that squeeze process can improve the density and mechanical properties of ZA27 effectively.A higher strength and a higher toughness can be obtained by controlling the process parameters.
