高W,Mo的GH220合金X光定量相分析

Quantitative X-ray Phase Analysis in GH220 Alloy with High Contents of Molybdenum and Tungsten

摘要: 应用X光定量相分析方法测出了高W、Mo含量的GH220合金中不同热处理状态下各析出相的含量,从晶体结构角度区分了M₆C和μ相,从而解决了化学相分析中由于M₆C和μ相主要元素组成及电化学性质相近而难以分离的困难,为研究合金性能变化,确定最佳W,Mo量提供了依据。

Abstract: The amount of four phase in GH220 alloy with high contents of Molyb denum and Tungsten at different heat treatment was determined by guantit-ative X-ray phase analysis.
X-ray diffraction method has identified the M6C and μ phase,those are Very difficult to determine by chemical phase analysis.
The result of thus research has Provided the basic data fo define the optimum Content of Wand Mo in GH220 alloy.
