摘　　要：本文研究了不同温度不同时间,均匀化退火处理对Zr变质ZA27锌合金的显微组织和硬度的影响。结果表明:Zr变质处理后,ZA27合金组织明显细化,硬度由55.8HB提高到59.0HB,均匀化退火处理后,硬度较变质后降低。The effect of uniform annealing treatment at different temperature and time on microstructure and hardness of Zr modified ZA27 zinc alloy was studied.The results showed that after Zr metamorphism,ZA27 alloy microstructure was obviously refined,and its hardness increased from 55.8HB to 59.0HB.After uniform annealing treatment,the hardness decreased compared with that after metamorphism.
