摘要
采用宏观分析、力学分析、化学分析、金相检验、扫描电镜等方法对多次出现裂纹的再热器出口联箱管接头(材质为12Cr1MoV)进行失效分析,结果表明,再热器联箱管接头裂纹属于再热裂纹,应力过大是造成泄漏的主要诱因。
By the methods of microscope analysis, mechanical analysis, chemical analysis, metallographic examination and SEM, the joint of boiler reheater connecting tube（12Cr1MoV） in which cracks occur many time was analyzed. The results indicate that the crack of boiler reheater connecting tube joint is the reheating crack and the primary season in which the cracks occur is excessive stress.
