Fabrication of Cu-graphite metal matrix composites by ball milling and spark plasma sintering

[Display omitted] •Graphite is used as a dispersoid to strengthen Cu.•Cu-graphite nanocomposites are fabricated by repeated two-stage processing cycles.•In each cycle, powders are ball milled and consolidated by spark plasma sintering.•Final nanocomposites exhibit a uniform dispersion of graphite na...
