用射线法定量分析三元相图

The Ray Method Applied to Quantitative Analysis of Ternary Phase Diagram

摘要: 作者提出一种新的方法–射线法–定量地分析三元相图，简单介绍了射线法的原理和方法。作为例子，用射线法定量分析了W-Cr-C三元相图等温截面二相区中的合金以及Fe-C-P三元相图投影图中高磷灰铸铁的结晶过程，计算了组织组成物的相对量。与高磷灰铸铁组织的对比结果表明，射线法是可靠的。

Abstract: In this paper, a new method-the ray method-was proposed for quantitative analysis of ternary phase diagram, and the brief principle and method of the ray method were introduced. As examples, the crystallization processes of an alloy in two-phase region of isothermal section of W-Cr-Ni ternary phase diagram as well as a high-phosphorus gray cast iron in projection of Fe-C-P ternary phase diagram were quantitatively analyzed by the ray method, and the relative amounts of structural compositions were calculated. The result of the comparison with the microstructure of a high phosphorus gray cast iron showed that the ray method is reliable.
