Alloy for single crystal technology. |
摘要 |
A single crystal casting of the following composition expressed as percent by weight:-… Co 9.3-10.0… Cr 6.4-6.8… Mo 0.5-0.7… W 6.2-6.6… Ta 6.3-6.7… Al 5.45-5.75… Ti 0.8-1.2… Hf 0.07-0.12… Re 2.8-3.2… Ni Bal. …<??>Such alloys exhibit exceptionally low steady state creep rates. …<??>Such single crystal nickel-base superalloy have very fime gamma prime after heat treatment in a temperature range permitting total gamma prime solutioning without incipient melting. A component of the heat treated alloy has exceptional resistance to creep under high temperature and stress, particularly in that part of the creep curve representing one percent or less elongation. |
