标准范围

本文件规定了使用电子探针显微分析（EPMA）定量分析钢坯、大方坯和板坯中锰树枝状偏析的程序。本文件主要适用于锰含量超过0.01？%（按质量计）的连铸产品。它也可用于钢锭和钢制品，如铸铁和铸钢。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。

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.
