Abstract
Alloying. Alloying process in mechanical alloying (MA) and reaction behavior in heating of Ni-Cu solid solution were analized. Alloying was occured in lower temperature and shorter time in accordance with the progress of MA, ie. the state of mixing Ni and Cu became higher. Resultant phase in MA and heat treatment was the same as the phase occured only in HA, but activation energy tended to decrease as the increasing time of MA. We concluded that non-equillibrium mixing phases that cannot be occured in conventional way can be formed in combination with MA and beat treatment.
