namely milling of a blend of silver and graphite powder particles in one case and milling of only elemental silver powder in the other. The study revealed that somewhat inferior properties are obtained for the AgC bulk solids prepared from powders synthesized by the former approach.The Al6061 powder and graphene were ball milled at different milling times. The composites were then synthesized by hot compaction in the semi-solid regime of the Al6061. A three point bending test was performed to characterize the mechanical properties of the composite. The ball milled powder and the fracture surfaces of the com-As a first step,
