标准摘要
[中文适用范围]： 本文件规定了使用电子探针微量分析 (EPMA) 对钢坯、钢坯、板坯中锰枝晶偏析进行定量分析的程序。 本文件主要适用于锰含量按质量计大于0.01%的连铸产品。 也可用于钢锭和钢制品，如铸铁、铸钢。 可分析枝晶的最小尺寸完全取决于EPMA显微镜的分辨率和用于定量分析的灯丝的光束尺寸。 [外文原描述]： This document specifies procedures for quantitative analysis of Mn dendritic segregation in steel billets, blooms, slabs using electron probe microanalysis (EPMA). This document is mainly applicable to continuously cast products with Mn content more than 0,01 % by mass. It can also be used for steel ingots and steel products, such as cast iron and cast steel. The minimum size of analysable dendrites is totally dependent on the resolution of microscope of EPMA and beam size of filament used for quantitative analysis.
英文名称Microbeam analysis — Electron probe microanalysis — Quantitative analysis of Mn dendritic segregation in continuously cast steel product
