钢晶粒度的截距直接测量法OA
Intercept direct measurement method of steel grain size
针对钢产品中双相或多相组织平均晶粒度难以评定的问题,以单相组织无间隙原子钢为试验对象,采用图像处理软件对单视场内截距测量数量进行确定,开发了一种采用截距直接测量法测量平均晶粒度的新方法,并将该方法应用于DH590、38MnVS、400E钢等含双相或多相组织材料的平均晶粒度评定.结果表明:截距直接测量钢产品平均晶粒度的方法简便可行、检验效率高、出错率低;测量结果与GB/T 6394-2017中截点法的测量结果基本一致;截距直接测量法既适用于单相组织…查看全部>>
In order to solve the problem that it was difficult to evaluate the average grain size of two-phase or multi-phase structure in steel products,taking single-phase structure interstitial-free atomic steel as the test object,the number of intercept measurements in a single field of view was determined by image processing software,and a new method for determining the average grain size by intercept direct measurement method was developed,which was applied to th…查看全部>>
