Abstract
The improved high temperature softening resistance of Alloy 688 and modified 688 is obtained by the addition of niobium to the alloys. These particular alloy systems not only exhibit resistance to high temperature softening, but also exhibit improved stress corrosion and stress relaxation resistance properties. All of these properties are attained without any loss in the high strength properties of the base alloy systems.
