A critical property of nickel-based superalloys is their resistance to fatigue-crack propagation, particularly at service temperatures. Many nickel-based superalloys are subject to formation of cracks or incipient cracks, either in fabrication or in use, and that the cracks can actually propagate or grow while under stress during the use in.
