5、ZM1具有良好的铸造性能、力学性能、高的抗蚀性和适合较高温度的工作环境等优点。研究了合金元素对ZM6镁合金力学性能的影响。结果表明,锌、钕、锆元素对ZM6合金的良好的强化效果,以锌的强
化作用最为强,其加入量分别为Zn0.4%~0.7%,Zr0.6%~0.7%,Nd0.4%~0.8%时,合金
的力学性能较高。使用高纯原材料,并辅以合理的熔炼工艺是获得综合性能优良的ZM6合金
的重要条件。
ZM6 magnesium alloy has been widely used in aerospace industries in recent yea
rs for excellent castability, mechanical property, corrosion resis
tance and suitability in high temperature conditions compared with the ZM5 and
ZM1 magnesium alloy. the influences of alloying elements were studied on the ZM6 magnesium alloy properties and mechanical properties. The results show that Zn、 Nd、 Zr have an good strengthening effect for ZM6 magnesium alloy. The best streng thening effect element is Zn. The Zn addition is Zn 0.4%~0.7%, Zr 0.6%~0.7%, Nd 0.4%~0.8%时, The mechanical property value is highest. High purity material and reasonable melting process are important to obtain excellent properties alloys.
