CrMnSiNi2A 钢的亮点亮线缺陷,于一九七二年由大冶钢厂、金属研究所、一一二厂共同进行系统试验研究,对它的性质和使用性能的影响,已有所认识,在冶炼生产上,初步找到了一定的控制措施,,现简述如下:一、亮点亮线的特征亮点亮线是在材料作拉伸试验时发现的。它住纵向试样断口上表现为亮点,住横向试样上表现为亮线.如图1所示。亮点亮线的名称 The bright spot of CrMnSiNi2A steel line defects, in Daye Steel, Institute of Metals, 112 plants jointly conducted a systematic experimental study of its nature and performance, has been recognized in 1972, at Smelting production, initially found some control measures, are summarized as follows: First, the bright features of the bright line Bright lines in the material for tensile testing found. It live in the longitudinal specimen fracture as a bright spot, living on the horizontal sample showed bright line, as shown in Figure 1. Bright light the name of the line
