EFFECTOF ENVIRONMENTONCREEP- RUPTURE PROPERTIES OF HASTELLOY 6 C. R. Kennedy' Revised design data obtained from creep tests of solution-annealed Hastelloy B sheet stock in various environments at 1300, 1500, and 1650°F ore summarized in Figs, 3.5.1, 3.5.2, and 3.5.3. The times to 0.5, 1, 2, 5, and 10% total strain at each temperature in the various environments are the same, and for stresses for which the rupture life is more than 300 hr the effect of environment is shown to be negligible. The creep curves obtained at 1500OF in air and in argon, shown in Fig, 3.5.4, appear to indicate that the better performance in air than in the other environments at stresses for which the rupture life is less than 'On assignment from Pratt 8, Whitney Aircraft. 3.5. MECHANICAL PROPERTIES STUDIES D. A. Douglas (0 20 50 400 200 TIME (hr) PERIOD ENDING JUNE 16, 1956 300 hr is caused by the ability of air to strengthen Hastelloy B during third-stage creep. For rupture lives longer than 300 hr there is considerably less third-stage creep because of the aging characteristics of the alloy, and, as seen in Figs. 3.5.1, 35.2, and 3.5.3, the effect of environ- ment diminishes. Design curves produced from limited data for solution-annealed Hastelloy B sheet tested at 1800OF in argon and in the fuel mixture (No. 30) NaF-ZrF,-UF, (50-46-4 mole %) are shown in Fig. 3.5.5. At 180OOF Hastelloy B does not age perceptibly and the amount of third- stage creep is great in tests at all stress levels. Thus the fuel dxture strengthens the alloy at all stress levels, Of the environments tested, only those which are "surface active" (produce a thin, tightly adherent film on the surface of the metal) affect the creep properties of the metal. It can be seen from Figs. 3.5.1, 3.5.2, 3.5.3, and 3.5.5 that, of the environments tested, only 500 tow 2 5FeRu ORNL-LR-DWG 14729 D 5000 10,Ooo Fig. 3.5.1.
