| 摘 要： | 采用液相烧结成形工艺制备了90W-Ni-Fe合金棒,通过分析烧结态钨合金的组织形貌和力学性能,观察合金的断口组织形貌,研究了烧结工艺对高比重钨合金组织性能的影响,认为减少W-W界面,增加W-W界面的结合强度,是提高烧结态钨合金力学性能的有效途径。

| Abstract: | The alloy bars of 90W - Ni - Fe have been made by liquid phase sinter. The microstrueture and mechanical properties of liquid phase sintered tungsten alloy have been analyzed. The stretch testing and fracture surface have been experimentally researched. The sintering progress' s influence on microstrueture and properties of liquid phase sintered 90W - Ni - Fe tungsten alloy are studied. It is found that reducing the W - W interface and increasing its combine strength can improve mechanical properties of tungsten alloy. |
