Abstract

X ray diffraction analysis and optical and scanning electron microscopy were used to characterize high-energy ball milled prealloyed copper powder containing 2.5 wt% Aluminum. The lattice parameter of the copper powder was found to decrease due to the oxidation of the dissolved aluminum. The microhardness of the compact was 3.5 times greater after five hours of milling.
