摘要	The internal oxidation technology of Al in Cu-Al pre-alloyed powders is discussed. The results show that the reacting temperature is a key factor to determine the critical oxygen partial pressure. The maximum oxygen partial pressure increases with increasing temperature, so that a little higher temperature than that of ordinary reaction is helpful to reduce the difficulty of controlling internal oxidation. High energy milling has little influence on the internal oxidation thermodynamics, however, remarkable influence on the internal oxidation kinetics. When the Al content exceeds 0.5%, the heating parameters should be alternated based on Al content. It can be observed from the examinations of the samples that the spherical Al2O3 particles with an average diameter size of 2-5 mum and particles spacing of 5-10 mum are dispersed in the Cu matrix uniformly, when used the suitable processing parameters of internal oxidation.
