The mieroporosity of these alloys may be substantially eliminated by the HIP technique: 100—120 MPa for 3h at 1150℃. After HIP, these superalloys of dense and homogeneous structure were produced as compared with conventionally casting process. Their rupture properties under different temperatures and stresses, tensile properties under different temperatures and LCF lives under different stresses may be remarkably improved for the notched and/or unnotehed specimens, as well the scattering bands of rupture and tensile properties may be evidently narrowed down. 收稿日期: 1984-05-18      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 黄荣芳 唐亚俊 李英敖 郭建亭 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I5/414 1 Wlodek, S. t. , Trans.
