Nickel-Base Super-Strength Alloys


The data on Inconel X-550 show a slight increase in relaxation strength with decreasing initial stress down to 50,000 psi at 1350 F. Even further decreases in initial stress would apparently cause additional increase in long-time relaxation strengths. The same trend is evident in the data for Waspaloy at both 1350 and 1500 F.
