Self-diffusion in the hexagonal structure of Zirconium and Hafnium. Computer simulation studies

Abstract

Self-diffusion by vacancy mechanism is studied in two metals of hexagonal close packed structure, namely Hafnium and Zirconium. Computer simulation techniques are used together with many-body potentials of the embedded atom type. Defect properties are calculated at 0 K by molecular static while molecular dynamic is used to explore a wide temperature range. © 2005.
