Abstract：The K17G cast Ni-base superalloy is the one of low density,high strength and good ductility.Due to the stability of microstructure and lack of harmful a-phase after prolonged aging at 750—950℃,its mechanical properties are slightly lowered only.Although the properties of samples cut and machined from turbine blades subjected also to prolonged aging were been some reduction, in comparison with those of standard precision-cast specimens,their tensile properties and ruptuce strength were still kept at rather high level. 收稿日期: 1987-01-18      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 王素坤 张炳大 胡壮麒 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I1/6 1 Piearcey B J,Smashey R W.Trans Metall Soc,1967;239:451 2 Collins H E,Quigg B J.ASM Trans Q,1968;61:139 3 Collins H E.ASM Trans Q,1969;62:82 4 Sabol G P,Stickler R.Phys Status Solidi,1969;35:11 No related articles found!
