【 摘 要 】

It was prepared that Cu20Fe80alloys using the mechanical alloying and cold pressing and the microwave sintering. The microstructure and the phase composition of Cu20Fe80alloy were analyzed by SEM and XRD, respectively. The density and hardness of the alloys were measured. The evolution rule of microwave of Cu20Fe80alloy was investigated during the microwave sintering. The results have shown that the powder milling structure of Cu20Fe80alloy is a flake layer which is refined and the mechanical alloying enhanced with increasing milling time; The microstructure of the Cu20Fe80alloy powder blank cold pressed is lamellar which gradually become dense, the density increases and the formability is improved with the increase of cold compressive strength; The microstructure of the Cu20Fe80alloys sintering was lamellar that the voids decreased and the grain boundaries were gradually obvious and the density increased and the hardness increased with the increase of cold compression strength and the milling time the best milling time was 4h.
