Microstructure of alumina-zirconia composite was successively controlled using nanopowder and fibrous monolithic process. The microstructure was examined by back scattered electron microscope (BSEM) and Transmission electron microscope (TEM). As the passes of extrusion increase, the aligned size the A12O3 and ZrO2 particles were homogeneously reduced in accordance with equation of Dn-1R1/2, where D is an initial diameter of the feed rod and R is an extrusion ratio. The calculated and measured data agreed well. The Al2O3 fibers of about 4-6 μm were distributed within the monoclinic (m-) ZrO2 matrix with an average thickness of about less than 2μm after four pass.
