The formation of η-phase was promotedby increment of titanium content as well as by hot-working energy, and was re-tarded by the addition of aluminium, molybdenum and minute boron. when suchan alloy did contain certain amount of η-phase, its rupture strength and/or stress-rup-ture life were reduced although its ductility and hot-workability were increased. 收稿日期: 1979-02-18      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 葛云龙 张永昌 侯翠萍 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1979/V15/I2/197 [1] Beattie, H.
