Sintering behavior of alumina whisker reinforced zirconia ceramics in hot oscillatory pressing

Abstract Alumina whisker reinforced zirconia ceramic composite was prepared by both hot oscillatory pressing (HOP) and conventional (HP). The results show that compared with HP, HOP can significantly increase the final density densification rate of material. Analysis kinetics reveals predominant mechanism transits from grain boundary sliding in beginning to diffusion later stage. main effect oscillating pressure is process sliding. current study suggests a promising technique for densifying ceramics.
