摘要

采用金相显微镜、扫描电镜观察和力学性能测试方法

研究了形变和热处理对微合金化Zn合金的组织与性能的影响。结果表明

随着变形量的增加

Zn-2.1Cu-0.06Ti合金的显微硬度呈现先增加而后减小的趋势

当冷变形量达到70%时显微硬度取得最大值;随着Cu含量的上升

导致Zn-Cu-Ti合金的显微硬度下降的温度也逐渐升高;一定范围内Cu的添加可以提高纯Zn的显微硬度和抗拉强度

Ti元素含量的增加可以改善Zn-Cu-Ti合金的韧性。

Abstract

Through hardness test

optical microscope

scanning electron microscope and mechanical properties test

influence of deformation and heat treatment on microstructure and properties of micro alloying of Zn alloy were investigated.The results show that

with the increase of deformation rate

microhardness of Zn-2.1Cu-0.06 Ti alloy is increasesd firstly and then decreased.When the cold deformation rate reaches 70% microhardness has a maximum value

with the increase of Cu element content

the temperature resulting in the descrease of micro-hardness of Zn-Cu-Ti alloy is increased gradually.The Cu element within a certain range of addition can improve the micro-hardness and tensile strength of pure Zn

and increase of Ti element can improve the toughness of the alloy.
