摘要
针对某公司铜套筒开裂及鼓包现象,通过宏观检验、金相检验、硬度测试等方法进行了分析。结果表明套筒存在过烧组织,在应力作用下导致开裂;同时,材料的化学成分对其性能的影响至关重要,因而应加强温度控制和原材料检查。
The cracking and bulging phenomenon of copper sleeve in a company were analyzed by means of macroscopic inspection,metallographic inspection and hardness test.The results show that there is overburning structure in the sleeve,which leads to cracking under stress.At the same time,the chemical composition of the material is very important to its performance,so the temperature control and raw material inspection should be strengthened.
