Title: Progress report on the influence of test temperature and grain boundary chemistry on the fracture behavior of ITER copper alloys

Abstract

This collaborative study was initiated to determine mechanical properties at elevated temperatures of various copper alloys by University of Illinois and Pacific Northwestern National Lab (PNNL) with support of OMG Americas, Inc. and Brush Wellman, Inc. This report includes current experimental results on notch tensile tests and pre-cracked bend bar tests on these materials at room temperature, 200 and 300 C. The elevated temperature tests were performed in vacuum and indicate that a decrease in fracture resistance with increasing temperature, as seen in previous investigations. While the causes for the decreases in fracture resistance are still not clear, the current results indicate that environmental effects are likely less important in the process than formerly assumed.
