DETERMINATION OF 30,000 HOUR CREEP DATA ON STRUCTURAL SHEET MATERIALS.
Abstract
Studies indicated that 650 exposure of AM350 material in the SCT condition and 550 exposure of Ti-8Al-1Mo-1V material in the 1450 F annealed conditions, at stresses calculated to produce 0.5% creep deformation in 30,000 hr, could only be realized at stress levels exceeding the yield strength. Since hyper-yield strength stresses are highly undesirable in terms of long-term load-carrying applications, an exposure stress of 67,000 psi was selected for the 30,000 hr tests. This stress level represents the probable maximum design stress that the vehicle, traveling at speeds approaching Mach 3, will require. (Author)
