Abstract:Al2O3/AC8A composites was prepared by squeezing casting with in-situ reaction technique. Thermodynamic and kinetic analysis indicates that the reactions in this system meet the requirement of thermodynamics. The main effecting aspects of speed are reaction temperature，the solution of melted aluminum and those object microcosmic moving state that could affect arranging functions.
