Abstract

Zirconium alloys undergo structural changes under various types of irradiation. This is particularly the case for intermetallic precipitates such as Zr₂(Fe,Ni), Zr(Fe,Cr)₂ in Zircaloys and Zr(Fe,V)₂ in Zr-Fe-V alloy: under irradiation those phases are subject to a crystalline-to-amorphous transformation. Experimental results obtained with electron and ion irradiations are presented. With both types of irradiations, the dose to amorphization increases with the irradiation temperature and diverges when a critical temperature is reached. The relative stabilities of the four types of precipitates studied appear to be reversed for low and high irradiation temperatures.
