摘要

采用挤压铸造工艺加工出了ZL2 0 1合金薄壁筒形件

并对其组织与性能进行了研究。结果表明 :ZL2 0 1合金适合于用挤压铸造工艺生产薄壁中、小型工件 ;经挤压铸造工艺加工出的薄壁筒形件几乎没有铸造缺陷

强度比砂型铸造提高约 5 4%

伸长率提高约 17%

显微组织比砂型铸造细密均匀。在挤压铸造过程中

薄壁筒形件的塑性变形由外向里进行

显微组织呈梯度变化。

Abstract

The microstructure and properties of ZL201 alloy thin walled cylindric parts in extrusion casting were investigated. The results showed that ZL201 alloy is suitable for thin walled medium

light parts in extrusion casting. The thin walled cylinderic parts in extrusion casting has almost no casting defects and its and strength and plasticity increased by approximately 54%and 17% respectively and microstructure is more homogeneous than in sand casting. Plastic deformation of the thin walled cylindric parts takes place from surface to inner sides and there exists gradient change in microstructure during extrusion casting process.
