Fatigue-crack growth tests were conducted on three heats of wrought material plus one heat of weldment at temperatures of 24, 316, 427, 538, and 593/sup 0/C. The effects of heat-to-heat variations, crack orientation, and thermal aging were studied. In addition, stress ratio effects were characterized at 427/sup 0/C. The J-integral technique was used to determine the ductile fracture toughness at room temperature. Both the multiple specimen and unloading compliance techniques were used, and differences between the two methods are discussed.
