摘　　要：研究了不同Mg含量的5B02合金退火处理和冷轧加工对5B02合金组织和性能的影响。结果表明:两种Mg含量的合金箔坯,在不同的加热退火温度下退火,其退火软化趋势基本相同。两种Mg含量的5B02合金在加工率为75%之前,硬化趋势基本一致。当合金冷轧总加工率超过75%以后,Mg含量高的5B02合金加工硬化速率明显加快。Effect various Mg contents on microstucture and property of 5B02 alloy was researched.The results show taht alloy foil stocks with two kinds of Mg content have the same annealing softening trend after annealing at verious heating and annealing temperature.5B02 alloy with two kinds of Mg content have the same haedening trend before 75% working rate.When the total working rate exceeds 75%,work hardening rates of 5B02 alloy with high content of Mg speed up obviously.
