在三种钨含量的Ｗ一Ｎｉ一Ｆｅ合金变形强化过程中，研究了变形量和力学性能与显微组织之间的关系。试验结果表明：随着钨合金变形量的增加，变形合金的强度和硬度亦增加，当变形量超过１５％后，高钨含量合金的变形强化作用逐渐减小。在变形合金的显微组织中，钨颗粒沿棒料轴向明显拉长，同时解理断裂成为断口的主要形式，并显现出钨合金断面上的滑移带。本文还讨论了变形合金在真空下，最佳调质退火温度和两相钨合金的形变特点、变形机制等。
In the W-Ni-Fe alloy with three tungsten contents, the relationship between deformation and mechanical properties and microstructure was studied. The experimental results show that with the increase of the deformation of tungsten alloy, the strength and hardness of the deformed alloy also increase. When the deformation exceeds 15%, the deformation strengthening effect of the alloy with high tungsten content decreases gradually. In the microstructure of the deformed alloy, the tungsten particles extend obviously along the axial direction of the bar, meanwhile the cleavage fracture becomes the main form of the fracture and shows the slip band on the cross section of the tungsten alloy. This article also discussed the deformation of the alloy under vacuum, the best quenching temperature and two-phase tungsten alloy deformation characteristics, deformation mechanism.
