内容記述 | "Recent computational and experimental studies have confirmed that high energy cascades produce clustered defects of both vacancy- and interstitial-types as well as isolated point defects. However, the production probability, configuration, stability and other characteristics of the cascade clusters are not well understood in spite of the fact that clustered defect production would substantially affect the irradiation-induced microstructures and the consequent property changes in a certain range of temperatures and displacement rates. In this work, a model of point defect and cluster evolution in irradiated materials under cascade damage conditions was developed by combining the conventional reaction rate theory and the results from the latest molecular dynamics simulation studies. This paper provides a description of the model and a model-based fundamental investigation of the influence of configuration, production efficiency and the initial size distribution of cascade-produced vacancy clusters. In addition, using the model, issues on characterizing cascade-induced defect production by microstructural analysis will be discussed. In particular, the determination of cascade vacancy cluster configuration, surviving defect production efficiency and cascade-interaction volume is attempted by analyzing the temperature dependence of swelling rate and loop growth rate in austenitic steels and model alloys." | |||||
