To investigate the interfacial reaction of metal powder after absorbing microwave radiation, pure metal powder composed of five elements, Fe, Co, Ni, Cr, and Mn, was microwave heated at four temperature gradients of 500, 800, 1000, and 1200 °C. At 1200 °C, the powder particles diffused to form an alloy. Mechanical alloying of the mixed metal powder was performed for 5, 10, 24, and 48 h to observe the changes of the powder. The size of the alloy particles first increased, then decreased, and then increased again. The powder mechanically alloyed for 48 h was microwave heated at 700, 800, 900, 1000, and 1200 °C. The alloy only formed at 1200 °C.
