摘要：
The diffusion reaction in the system of Co/Al and Mn/Al was researched with OM, SEM and X-ray diffraction methods. The specimen of Co/Al and Mn/Al was prepared through powder metallurgy technology. The experiment was analyzed according to the TFDC model. The results showed that, due to the adhesive energy of Co crystal was larger than that of Al crystal, Al atoms may diffuse into Co crystal in Co/Al system, and the intermetallic compounds CoAl and Co2Al5 were formed, and the former was more than the latter. The composition of CoAl was closer to Al than that of Co2Al5. In Mn/Al system, due to the adhesive energy of Al crystal was larger than that of Mn crystal, Mn atoms may diffuse into Al crystal, and the intermetallic compounds Mn5Al8, Mn22 Al78, MnAl6 were formed. The quantity of MnAl6 was larger than others, and its composition was closer to that of Al.
