Dynamic deformation of aluminium and copper at elevated temperatures
TL;DR: In this article, the authors investigated the rate sensitivity of two annealed face-centred cubic metals, aluminium and copper, at elevated temperatures to determine their rate sensitivity, and the results indicate that hot compression is a thermally-activated process.
