摘要：

It is suggested that a model-based analysis of the relationship between microstructure and properties and relatively simple properties, such as tensile data and fracture/failure parameters is one useful component in the overall effort to predict structural response in fusion reactor environments. The approach is applied to modeling yield strength changes in irradiated stainless steel with apparent success. Further analysis of ductility data may suggest significant changes in fracture mechanisms in highly irradiated stainless steel. Finally, a simple micromechanical model is used to estimate changes in fracture toughness; while there is not sufficient confirmatory data, the calculations indicate a substantial reduction in toughness due to irradiation. © 1979.
