本文就GH437合金X射线定量分析中的一些具体问题进行了试验探讨。在无法获得纯相的情况下,应用解联立方程自动求取K值。并在求得K值后,进一步对合金中的Laves相和μ相的重叠谱线,通过列方程进行强度分配。从而获得了GH437合金在不同热处理条件下,MC相、Laves相、μ相的析出规律。一、基本原理 1.联立方程求K值假设有二个含量不同,但都为i相和j相组成的二相混合物。在试样1中掺入重量分数为x_(s1)的内标相S以后,测得三相各自的一根互不干扰的衍射线强度I_(1i)、I_(1j)、I(1s)。根据
In this paper, GH437 alloy X-ray quantitative analysis of some of the specific issues discussed. When the pure phase can not be obtained, K-value is automatically calculated by applying the simultaneous equations. And after obtaining the K value, the intensity distribution of the Laves phase and the μ phase in the alloy is further intensified by the column equation. The precipitation rules of MC phase, Laves phase and μ phase of GH437 alloy under different heat treatment conditions were obtained. First, the basic principle 1. Simultaneous equation for the value of K Suppose there are two different levels, but both phase i and phase j consisting of two-phase mixture. After the internal standard phase S with the weight fraction of x_ (s1) was incorporated into the sample 1, the intensity of the diffraction lines I_ (1i), I_ (1j), I (1s) . according to
