摘要
通过对1.2738大型锻造模块探伤密集缺陷取样进行低倍酸蚀、制备人工断口进行体视显微镜观察、扫描电镜(SEM)断口分析,确定缺陷性质为"白点",并在之后的生产实践中采用针对性的的工艺调整技术手段有限地消除了该类探伤缺陷。
Based on analysis of cluster defects in sample taken from 1.2738 large size moulds, the defect type was determined, that is "white spot". By modification of the manufacturing process, the formation of such defects could be avoided substantially.
