Microstructure and properties of graphite-reinforced ...
In this study, copper matrix composites reinforced with graphite (5, 10, 15 wt%) were produced using powder metallurgy process. Milled powders were compacted under 637 MPa pressure to produce cylindrical specimens of approximate dimension of 10 mm diameter and 30 mm length. Cylindrical specimens were sintered under vacuum at 900, 950, 1000 °C for 2 h holding time at …
