摘    要：介绍了2Cr13Mn9Ni4高合金钢光谱分析用标准物质的研制过程,包括采用合理的冶炼锻轧工艺,不同部位样品的均匀性检验,C、Si、Mn、P、S、Cr、Ni、7个元素的认定值及扩展不确定度的确定,成线性、一致性考察以及与国内外同类标准物质的比对。结果表明,本套高合金钢光谱分析用标准物质的均匀性良好,定值准确且有良好的梯度分布,对定值元素进行成线性考查,线性关系良好,能覆盖2Cr13Mn9Ni4高合金钢的成分范围,适用于类似高合金钢元素的成分分析。

Abstract: The development process of high-alloy steel certified reference materials (CRMs) 2Cr13Mn9Ni4 for spectral analysis was introduced,including the use of proper smelting and forging techniques,the homogeneity test of samples from different positions,the confirmation of certified values and expanded uncertainties of C,Si,Mn,P,S,Cr and Ni,the investigation of linearity,uniformity and comparison of congeneric certified reference materials (CRMs) at home and abroad.The results showed that the homogeneity of developed certified reference materials(CRMs) for spectral analysis was excellent with accurate certified values and good gradient distribution.The linearity of characterization elements was good,which could cover the content range in high-alloy steel 2Cr13Mn9Ni4.The developed certified reference materials (CRMs) was applicable for the component analysis of other similar high alloy steels.
