Microbeam analysis—Electron backscatter diffraction—Quantitative determination of austenite in steel


Standard in brief
Scope of Application:  
本文件规定了采用电子背散射衍射(electron backscatter diffraction,EBSD)法测量钢中奥氏体体积分数和形态的方法、设备、取样和试样制备、测量步骤、数据处理和检验报告。
本文件适用于分析含有晶粒尺寸50 nm以上奥氏体的中、低碳钢及中、低碳合金钢。
本文件不适用于分析晶粒尺寸小于50 nm的奥氏体,奥氏体晶粒尺寸小于50 nm会严重影响定量分析结果的准确性。
注: 晶粒尺寸下限是可观察到的最小奥氏体晶粒尺寸。晶粒尺寸下限取决于设备条件和操作参数。
