最近F.H.Chung提出了X射线定量分析的新方法:母体冲洗法(本文称为“K”值法)和绝热法。但是作者对该方法的导出繁琐而且混乱,因此我们对该方法从另一角度进行推导。本文介绍了两种新方法的原理、特点及操作程序。本文还介绍了克服X射线定量分析工作中衍射线相互干扰的办法。 170合金析出了μ相、M_6C相、M_6C’相、Zr(CN)相及α相。合金在改变元素加入量及热处理制度时一般只析出前面三种相。Zr(CN)相为微量相,α相只是在特殊情况下方才析出。而前面这三种相的化学及电化学性质非常近似,它们的金属元素组成亦近似,均
Recently F.H.Chung proposed new methods of quantitative X-ray analysis: the mother wash method (referred to herein as the “K” value method) and the adiabatic method. However, the author’s derivation of this method is tedious and confusing, so we derive this method from another perspective. This article describes the principles, characteristics and operating procedures of two new methods. This article also introduces ways to overcome the mutual interference of diffraction lines in quantitative analysis of X-rays. 170 alloy precipitated μ phase, M_6C phase, M_6C ’phase, Zr (CN) phase and α phase. Alloy in changing the amount of elements and heat treatment system generally only precipitates the first three phases. The Zr (CN) phase is the minor phase, and the alpha phase is precipitated only under special circumstances. The chemical and electrochemical properties of the three preceding phases are very similar, and their metal elements are similar
