【摘要】 阐述了用电子探针做显微分析的特点，拟定出了Ｗ－Ｎｉ－Ｆｅ合金断口分析和显微组织分析的方法；在断口分析中，讨论了断口样品制备、合金缺陷的观察和合会断裂的主要形式等问题；在显微组织分析中，讨论了抛光磨片制备、胶结相成分的测定、（ＮｉＦｅ）６Ｗ６Ｃ碳化物相的测定和Ｗ晶粒度的测定等问题。更多还原

【Abstract】 The paper describes the features of EPMA method and its applications to microanalysis of W-Ni-Fe alloy fractures and microstructures. In the first case, it details the preparation of fracture sample, defect observation and major fracturing type in the second,it details the proparation of polished microsection, and determination of the binding phase constituents, (NiFe)6W6C carbide phase and W grain size.更多还原
