An investigation on morphology and structure of Cu-Cr alloy powders prepared by mechanical milling and alloying

Cu and Cr powders were pre-milled separately, and then mechanically alloyed with as-received Cr and Cu powders respectively in a wet condition. The same experimental conditions were maintained for mechanical alloying of Cu and Cr without pre-milling. The morphology and structure of the powders during the fabrication process were studied.
