Characteristics of Cu-Al2O3 composites of various starting particle size obtained by high-energy milling
The powder Cu-Al2O3 composites were produced 20wm01snus by high-energy milling.Various combinations of particle size and mixtures and approximately constant amount of Al2O3 were used as the starting materials.These powders were separately milled in air for up to 20 h in a planetary ball mill.The copper matrix was reinforced by internal oxidation an
