Experimental nickel-base alloy exhibits exceptional low-cycle-fatigue strength in hydrogen. Alloy one of many intended to be produced by strategy of formulating compositions having potential for exceptional low-cycle-fatigue strength in air, casting these alloys into single crystals, and processing them in such ways that their microstructures contain minimal numbers of both sites favoring initiation of fatigue and sites having high surface energies for entrapment of, and infiltration by, hydrogen.
