This work reports on the use of graphite as dispersoid to strengthen Cu. Material processing involved two-stage cycles of ball milling and spark plasma sintering, respectively for the dispersion of graphite nanoparticles into nanostructured Cu and the formation of dense compacts with relatively large Cu grains. The 3 wt% of graphite allows progressive hardening and stiffening of the Cu-graphite composite, showing the potential of graphite as effective dispersoid upon suitable processing.

Abstract

This work reports on the use of graphite as dispersoid to strengthen Cu. Material processing involved two-stage cycles of ball milling and spark plasma sintering, respectively for the dispersion of graphite nanoparticles into nanostructured Cu and the formation of dense compacts with relatively large Cu grains. The 3 wt% of graphite allows progressive hardening and stiffening of the Cu-graphite composite, showing the potential of graphite as effective dispersoid upon suitable processing.
