摘要：
The hot deformation behaviour and microstructure evolution of the Cu-6.5Fe-0.3Mg alloy were explored. The optimum hot working temperature of the alloy was 950? and the strain rate was 10 s(-1). The alloy underwent dynamic recovery (DRV) and dynamic recrystallisation (DRX) behaviour during hot compression. The density of the Fe phase particles increased significantly, and they were all aligned along the vertical compression direction. The alpha-Fe phase transformed to gamma-Fe phase at 950?. A large amount of alpha-Fe and gamma-Fe phases effectively inhibited the DRX behaviour of the Cu-6.5Fe-0.3Mg alloy and significantly improved its thermal stability. The research on the hot deformation behaviour of the Cu-6.5Fe-X alloys had a theoretical guiding role in determining its hot working process.
