tungsten alloy with high specific gravity brittle fracture fracture analysis
- 摘要:
- 通过化学成分、宏观断口、微观断口和金相显微组织分析等手段,对发生断裂的高比重93WNiFe钨合金爆炸部件进行断裂失效分析研究。结果表明,失效部件合金的化学成分正常,但微观组织与密度存在异常;爆炸部件失效断裂的根本原因是材料制备过程中热处理工艺不当造成的;应严格控制热处理工艺和爆炸部件的检验方案。
By means of chemical composition,macroscopic and microscopic fracture and metallographic microstructure analysis,fracture failure analysis of high specific gravity 93WNiFe tungsten alloy explosive components were studied.The results show that the chemical composition of the alloy is normal,but the microstructure and density are different.The fundamental cause of failure and fracture of explosive parts is caused by improper heat treatment process in the process of materials preparation.The heat treatment process and the inspection scheme of explosive parts should be strictly controlled.
