摘　　要：通过不同平底孔绘制的AVG曲线检测厚度200mm左右锻件的不同深度、不同大小的缺陷,研究所显示缺陷的当量大小跟不同缺陷有什么相对应的关系,从而选择最合适的AVG曲线进行实际检测。The AVG curve drawn through different flat bottomed holes was used to detect defects of different depths and sizes with a thickness of about 200mm. The study showed that there was a corresponding relationship between the equivalent size of defects and different defects, and thus the most appropriate AVG curve was selected for actual detection.

关 键 词：AVG曲线 缺陷当量 锻件检测
