Influence of stacking faults and alloy composition on irradiation induced amorphization of ZrCr{sub 2}, ZrFe{sub 2} and Zr{sub 3}(Fe{sub 1-x},Ni{sub x})
Description:
These Zr-based intermetallics were irradiated with high-energy electrons at the ANL HVEM/Tandem facility. Although ZrCr{sub 2} and ZrFe{sub 2} have the same Laves phase C15 fcc crystal structure, their critical temperatures for amorphization under electron irradiation were 180 and 80 K, showing that Cr substitution for Fe in the sublattice had a marked effect on annealing. The low temperature dose to amorphization was higher in ZrFe{sub 2} than in ZrCr{sub 2} by a factor of two. Presence of a h…
