Description

The characteristics of microstructural evolution due to particle radiation are predicted by computer simulation for a physics system which includes cascades, helium gas. Frenkel pairs bubbles interstitial clusters (or dislocation loops) and dislocation network. Nonequilibrium statistical concepts and method are used in this simulation. The simulation predicts the experimental results for irradiation with 600 MeV protons at the PIREX facility and also reveals the whole evolution process, as well as a fluctuation coefficient and its behavior. The calculated results, including bubble size distribution, interstitial cluster size distribution, helium concentration in matrix, bubble and interstitial cluster nucleation rate bubble and interstitial cluster growth rate and evolution process, are all reasonable when compared to experimental results.
