“…It should be emphasized that W–Cu composites have to bear harsh wear processes and high-temperature loads in numerous service conditions [ 12 , 13 ]. Therefore, both wear resistance and high-temperature characteristic are essential indicators for high-end applications of W–Cu composites [ 14 ]. However, most studies to date have mainly focused on investigating the hardness and strength of W–Cu composites at room temperature [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”
