High-Temperature Low-Cycle Fatigue Experiments on Hastelloy X


Low-cycle fatigue behavior of Hastelloy X at elevated temperature is presented. We studied the effects of test temperature, cycle frequency, and stress temperature arrangement with special attention given to the minimum ductility (short-time tension test) at or near 1300 F. Isothermal fatigue data at 800, 1300, 1500, and 1800 F are presented along with strain controlled thermal fatigue data for temperature ranges of 600 to 1800, 800 to 1300, and 1800 to 1300 F. The method of universal slopes can be used to describe the fatigue behavior under elevated isothermal and cyclic thermal fatigue conditions. The thermal fatigue behavior determined from controlled strain tests can be applied to the thermal cycle behavior of bundles of thin tubes joined to a rigid plate.
