| 摘 要： | 通过化学成分分析、裂纹宏观和微观检验、显微硬度测试与微区成分能谱分析等方法,分析了H68黄铜弹壳开裂失效的原因。结果表明：材料本身存在冶金缺陷β相偏析与零件收口处退火不良是造成弹壳开裂失效的原因。

| 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. |
