The correlation among the degree of reduction,mechanical properties and microstructure of three W-Ni-Fe alloys with different W contents has been in-vestigated in deformation strengthening process.The experimental results showed that the strength and hardness of the deformed alloys increased with the degree of deformation. Moreover,the deformation strength-ening effect of the higher W content decreased as the deformation was higher than 15 %,and the W grains were alongated along the longitudinal direction in the deformed alloys. The cleavage failur across W grains became the main mode of fracture and the slip bands emerged on the fracture face.The optimal temperature of vacuum annealing of deformed alloys,and the char-acteristics and mechanism of deformation of biphase W alloys have been discussed in this paper as well.

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。

The effect of pulse electric current on the superplasticity of the common treated Zn 22% Al alloy was studied. The results showed that the elongation of the alloy was appreciably increased, which was characterized by a higer m value, and the optimum superplastic deformation temperature was enlarged to be a temperature range. With the SEM, we could find that part of the alloy exhibited strong deformation strengthened character, and concurrently occurred high stress relaxation. These two processes reached...

The effect of pulse electric current on the superplasticity of the common treated Zn 22% Al alloy was studied. The results showed that the elongation of the alloy was appreciably increased, which was characterized by a higer m value, and the optimum superplastic deformation temperature was enlarged to be a temperature range. With the SEM, we could find that part of the alloy exhibited strong deformation strengthened character, and concurrently occurred high stress relaxation. These two processes reached dynamic equilibrium, which increased the homogeneous deformability effectively.
