The mechenical properties, surface topography and microstructure have been studied. A strong grain refinement and an age hardening response have been observed in the as-quenched and annealed specimens, respectively. The precipitates which are responsible for age hardening were identified to be Mo_2B(C16, BCT) in Mo-B alloys and Mo_2B and more stable ZrB_2(A_3) in Mo-Zr-B alloys. The alloys in which the borides are as strengthening phases possess very high strength and hardness, indicating the prospect of developing high strength Mo-base alloys by rapidly solidified techniques. 收稿日期: 1987-06-18      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 宁远涛 S.H.Whang 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I6/491 1 Whang S H, Giessen B C.
