无损精确定量测量二元合金成分探讨

Nondestructive composition quantitative analysis methods for binary alloys

采用三种成分分析方法定量测量了二元Ni-W合金试样的成分变化区。三种方法分别为密度转换成分法、微观组织转换成分法和X射线荧光光谱分析(XRF)。对比三种分析方法测得的数据表明,密度转换成分法和微观组织转换成分法都能够精确地测定合金成分,而其中微观组织转换成分法还可以在保持试样完整的情况下得到测试结果。

The composition profiles of Ni-W binary alloy samples were determined by three composition analysis methods,density-composition conversion microstructure-composition conversion and XRF.The result data comparison shows that the sample composition profiles determined by the first two methods agreed well with the XRF results.The microstructure conversion method can obtain data without destroying the integrity of the sample.
