Characterization of Al-Cu-Graphite nanocomposite prepared by powder metallurgy and mechanical alloying

Al-Cu composite has good mechanical properties and corrosion resistance but lower toughness and ductility which limits them at high temperature application. Al-Cu could reinforced with graphite (C) to overcome the problem by producing Al(C) or Cu(C) solid solutions. In this study, the effect of mill...
