浅谈铸件ASTM E图谱评定分析与应用

摘要

通过对标准评定图谱ASTM E446(ASTM E186、ASTM E280)的解读分析,结合实际RT探伤拍摄的底片对比,用量化的数据对缺陷进行分析.%Because of the diversity,internal casting and near surface complexities and casting process casting structure is formed of various defects.Comparative analysis of production radiographs and Standard Reference Radiographs ASTM E446 (ASTM E 186,ASTM E280) based on quantitative data is made for defecting evaluation in this paper.
