摘要
针对大尺寸G50钢按照GB/T1979标准图片检测评定过程中,存在斑点状偏析和疏松点归类分歧,进行了典型试样分析、探讨,界定了正确判断并区分开两种缺陷的原则和方法,为以后正确评定此种低倍缺陷打下基础。
Pointing at the problems that happened in the process of testing big size G50 steel according to the rat?ing charts in GB/ T1979 standard, and the arised disputes on spot-shaped segregations and porosities classification, the typical sample was analyzed and discussed, and thus,the principle and method to correctly judge and distinguish the two above-mentioned defects was suggested to lay a foundation to correctly define this kind of macro defects in fu?ture.
