The microstructure of composites for ball milling time to 20 h is equiaxed grain, and when the ball milling time reaches 40 h, the microstructure transformed into lamellar grain. There is a small amount of equiaxed Cu in the composite for ball milling 40 h, all transformed into creeping Cu when the ball mill is 60 h.

Introduction: 'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A ball mill is a type of grinder which consists of a cylinder. It is used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. The cylinder rotates around a …
