Abstract

The cracking reason of H68 brass shell was analyzed by means of chemical composition analysis, macroscopic and microscopic examination of crack, microhardness testing, energy spectrum analysis of micro area composition and so on. The results showed that the metallurgy defects of β phase segregation existed in materials and the undesirable annealing of part convergent resulted in cracking on the shell.
