Paper Title:
Effect of Ball Milling on Mechanical Properties of Graphite/Copper Matrix Composites
  Abstract

3wt% graphite/copper matrix composites had been prepared after mechanical ball milling, pressing, vacuum hot pressed sintering and hot extrusion. With tensile test, hardness test and impact test, utilizing material testing machine, Vickers hardness tester, impact machine, optical microscope and scanning electron microscopy, effect of milling time on mechanical property of graphite/copper matrix composites had been investigated. The results show that after mechanical milling and hot extrusion, microstructure had been refined, distribution of graphite phase and cohesion between copper and graphite had been improved, mechanical locking force between copper matrix and graphite, tensile strength and hardness of composites had been increased. Elongation percentage and impact absorption work are less resulting from work-hardening during ball milling.
