摘　　要：为了解决固溶度测定周期长、测定工作量较大的问题,提出了基于定量相分析的固溶度测定方法.该方法通过最小二乘法拟合多相区样品的物相定量分析结果和样品组元成分,可以快速得出固溶体的固溶度.在物相定量分析精确度高和组元成分精确的情况下,能很好地得出固溶度;若物相定量分析精确度不是很高,也可以快速得出固溶度的范围.A method was suggested to save the testing time in measuring solid solubility.This method was based on quantitative phase analysis technology,and could obtain the solid solubility quickly by using the least square method to fit the quantitative phase component result and the alloy element component result.The method could provide a fairly accurate solid solubility if the results of phase analysis and element analysis were accurate enough.It could also predict solid solubility which was useful to accurate measurement.
