Abstract

The morphology and relative quantity of α

β′ phases in microstructure are altered and constituent and distribution of inclusion are improved through adding RE element Ce to H62 brass and using recrystallization annealing. The quantitative relationship between microstructure characteristics and mechanical properties is obtained by measuring relevant mechanical property parameters. The results showed that there is a obviously corresponding relation between relative quantity of α

β′phases

distribution of β′ phase and mechanical properties in H62 brass. The inclusion improvement is also favorable to property improvement.
