ABSTRACT:
A composite zirconium alloy component that exhibits a reduced propensity for irradiation growth and enhanced corrosion resistance when in a radiation field. The component is formed to have an inner core and two oppositely-disposed outer layers that are metallurgically bonded to the inner core. The inner core and the outer layers are formed from two different zirconium alloys, with the inner core alloy contributing to the ability of the component to resist dimensional distortions as a result of irradiation growth, while the outer layer alloy contributes to the ability of the component to resist corrosion. As such, the alloys are combined within the component in a manner that exploits the different corrosion and irradiation-resistance properties of the alloys.
