copper powder milling reformhaus-schaer

During milling the copper powder suffers repetitive welding and fracture allowing for the formation of new interfaces across all the different powders. Meanwhile the reinforcement phases are fragmented and their particles tend to become occluded by copper and trapped in the ductile particles.
