The evolution of microstructure in the oxidative growth of Al2O3/Al alloy compeites was examined metallographically and analyzed by electron microprobe technique. The development of a nonprotective surface layer of MgO/MgAl2O4 allowed the continuous formation of an Al2O3-matrix composite containing an interpenetrating network of metal microchannels at 1373 K. The role of Mg in the composite growth process was discussed by means of the lg αo2-YMg phase diagram assuming that local equilibrium was established at the phase boundaries.
