Powder pre mixture of SnO2 and silver was tumbler-ball milled to investigate the influence of milling effect on the phase separation between oxide phase and matrix phase during heat treatment of mechanical alloyed oxide dispersided metal matrix composite particles. The milled powder for period milling time was heat treated in the air atmosphere, and the microstructure and phase formation during heat treatment were monitored by X-ray diffraction analysis(XRD), optical microscopy, SEM, EPMA and DTA. The cross section area ratio of the pure silver to total particle of the heat treated composite particles was measured with heat treatment temperature as function of milling time and volume fraction of SnO2, using image analysis system. The separation between dispersion phase, SnO2, and matrix phase, silver, was occurred when heat treated over the critical temperature of the composite particle milled over the period milling time. It considered that the separation phenomenon between dispersion phase and matrix phase during heat treatment was caused by mass transfer started by the release of internal energy which stored in the composite particle during mechanical alloying.
