Characteristics of Cu-Al2O3 composites of various starting particle size obtained by high-energy milling
The powder Cu-Al2O3 composites were produced by high-energy milling.Various Anal 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 and mech
