【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。更多还原

【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.更多还原
