It was resulted that the strength and hardness of the alloys increase with the increase of their W contents. However, the alloys of higher W contents have no more strengthened under the reduction beyond 15%. The room temperature tensile strength and hardness may be increased about 50% if it is of 93% W. Their microstructure markedly shows that the W grains are elongated along the longitudinal working direction. The cleavage failure across W grains becomes the main mode of fracture and the slip bands can be observed on them. The deformation feature and the mechanism of these biphase W alloys have been also discussed. Furthermore, it is suggested that the superior mechnical properties as a whole of the alloys may be produced by the vacuum annealing at the temperature between 800—1200℃. 收稿日期: 1983-06-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 朱桂森 刘铭成 甄振先 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I6/45 1 Krock, R.H.; Shepard, L.A., Trans.
