Molecular dynamics study of electron irradiation-induced amorphization of Ni-Zr intermetallic compounds
- Argonne National Lab., IL (United States); and others
The authors present the results of a systematic molecular dynamics simulation of the crystalline-to-amorphous transformation in the ordered intermetallic compounds of the Ni-Zr system, NiZr, NiZr{sub 2} and Ni{sub 3}Zr. Using embedded-atom potentials fitted to the equilibrium properties of these compounds, the simulation examines the relative importance of chemical disordering and point defect generation in inducing amorphization. Fundamental aspects of the amorphization process have been investigated in detail by monitoring the changes in the potential energy, volume, radial distribution function, structure factor and elastic constants as a function of irradiation dose. The results obtained are compared with recent experimental observations.
