摘要

对比研究了金属型重力铸造和挤压铸造下ZA27合金的显微组织、力学性能以及摩擦磨损性能。结果表明

挤压铸造可有效减少甚至消除ZA27合金的缩孔、缩松缺陷

细化晶粒组织

改善晶界富铜ε相形态及分布

使强度、塑性及耐磨性得到显著提高。

Abstract

Microstructure and mechanical properties as well as friction and wear behavior of squeezing casting ZA27 alloy were analyzed comparatively with those of permanent mould casting ones.The results reveal that squeeze casting process can decrease or eliminate shrinkage porosity（holes）

refine microstructure and improve the shape and distribution of copper-richεphase

which are responsible for the improvement of the mechanical properties

such as tensile strength

elongation and wear behavior.
