Abstract
The weld zone in Hastelloy X nickel superalloy is thermal mechanically worked by cold working the weld zone to reduce its thickness by about 5-40%, and by annealing at 1120.degree.-1175.degree. C. for one hour to cause recrystallization. Low cycle fatigue properties of laser and gas tungsten arc weld zones are substantially increased.
