Radiation-induced changes in electrical conductivity of a wide range of copper alloys

摘要

A wide variety of radiation-induced changes in electrical conductivity was observed in a series of irradiation experiments conducted on copper alloys in FFTF/MOTA. The behavior of each alloy was found to depend on the alloy composition, starting state, irradiation temperature, and the sometimes complex interaction of three radiation-driven processes. These processes are transmutation, void swelling, and solute redistribution. The objective of this effort is to identify those copper alloys that offer promise as high heat flux materials for fusion application. 13 refs., 4 figs., 2 tabs.
