| Abstract Scope |
Heterogeneous materials have been of recent interest due their enhanced mechanical response (namely, the excellent combinations of strength and ductility). Of less interest has been the stability of the gradient grain structures outside of ambient conditions, and there for a strong opportunity exists to explore the effects of temperature, mechanical load and radiation on the microstructural evolution in these unique systems. In this study, we will report our results on gradient heterogeneous copper produced by mechanical attrition in a SPEX mill, where the heterostructure is imparted by impacting media. Results on the stability after isochronal annealing, mechanical and wear properties, and radiation will be presented and compared with the current literature. These results will forecast the ability of heterostructured materials to be used in environments outside of static, ambient conditions. |
