摘要
对生产中65Mn带锯钎焊接头断裂的问题进行了失效分析,通过对接头的化学成分、金相组织及断口的扫描电镜分析、接头的力学性能测试,找出了断裂原因,研制了新的铜基钎料,解决了这个问题。
Analysis is made to the fracture phenomenon in brazing joints of 65Mn steel saw blades during its application. From the results of chemical composition analysis, metallurgical structure and SEM on fracture surface and mechanical property tests,the reasons of fracture aro found out. A new copper base filler metal is then developed in order to overcome the problems.
