为研发 W 合金新体系及其相应的制备技术，采用真空非自耗电弧熔炼方法制备了 W37．5 Fe56．9 B11．6和W18．4 Fe67．7 B13．9两种合金，利用光学显微镜、X射线衍射、扫描电镜和能谱仪分析了合金内部的相组成、组织形态及元素含量，并对合金的密度及压缩性能进行了测试和分析．研究表明：真空电弧熔炼W37．5 Fe56．9 B11．6和W18．4 Fe67．7 B13．9合金的密度分别为13．3和10．7 g／cm3；两种合金组织中分布着大量脆性相；W37．5 Fe56．9 B11．6合金的压缩屈服强度和最大压缩强度分别为2240和2321 MPa，而W18．4 Fe67．7 B13．9合金的压缩屈服强度和最大压缩强度分别为2400和2457 MPa；压缩后两种合金断口呈脆性断裂，断口局部有熔化现象．
In this study, alloys of W37.5Fe56.9B11.6(at.%)and W18.4Fe67.7B13.9(at.%)were prepared by vacuum non?consumable arc melting. The phase composition, morphology and elemental content were investigated by optical microscope ( OM ) , X?ray diffraction ( XRD ) , scanning electron microscope ( SEM ) and energy dispersive spectroscopy (EDS), respectively. The density and compression behavior were detected and analyzed. The results showed that the density of W37.5Fe56.9B11.6 and W18.4Fe67.7B13.9 was 13.3 g/cm3 and 10.7 g/cm3. Many brittle phases were observed in the two alloys. The yield strength and the maximum compressive strength of W37.5 Fe56.9 B11.6 were 2 240 MPa and 2 321 MPa, whereas those of W18.4Fe67.7B13.9 were 2 400 MPa and 2 457 MPa, respectively. Both of the alloys showed visible brittle fracture, on which there was partial melting phenomenon.
