Notes:
In this paper, X-ray diffraction (XRD), differential scanning calorimetry (DSC) andsintering process were used to characterize Cu-Fe compound powders milled for different times.The increment of defects and the change of granularity, grain size and crystal structure werediscussed. Mechanical Alloying (MA) influence on the sintering of Cu-Fe compound powders wasanalyzed. The results showed that, the refinement of the powders and the increment of defects suchas interface and dislocation induced the energy storage. The stored energy released in the sinteringprocess, which reduced the activation energy of vacancy and the activation energy of diffusion. Sothe sintering temperature was reduced and the structure, strength and hardness of specimens wereimproved
