Fabrication And Characterisation Of Copper Composites Reinforced With Transition Metal Carbides Via Mechanical Alloying

In this study, high-energy ball milling also called mechanical alloying (MA) was applied to synthesis in situ copper based composite. Cu, M (M=W or Ti) and graphite powder mixture were mechanically alloyed for various milling time in a planetary ball mill. The nominal composition was Cu-28.72wt%W-1....
