摘要: 用金相、X射线衍射相分析和透射电镜观察等手段,细致地考察了含90和95Wt-%w的四种液相烧结W-Ni-Fe合金的微观组织.发现含90wL-%W的合金中,只要有少量的杂质碳存在,在液相烧结后缓冷的条件下将有析出相产生.经鉴定它是A_6B_6C型碳化物,其结构属于复杂立方晶系(面心立方晶格),晶格常数为1.0935nm;化学组成式可近似写成(Ni,Fe)6_W _6C;其形貌随着冷却速度大小而变化。通过各种热处理试验,找出了(Ni,Fe)6_6W_C相的形成和消除规律.
Abstract:The microstructure of four liquid-phase-sintered W-Ni-Fe altoys with 90-95 wt-%W was investigated by means of optical and electron microscope and X-ray diffraction. It was found that there would be a precipitated phase formed in the 90W-Ni-Fe alloy in presence of a little carbon impurity and under the condition of slow-cooling after Iiquid-phase sintering. It was identified as a kind of A_6B_6C carbide of compiex face-centered cubic system with lattice constant of 1.0935 nm. Its morphology varies with the cooling speed and its empiric formula can be written as(Ni, Fe)_6W_6C approximateiy. After studying the heat treatment, the formation or elimination of this phase can be controlled.
