The Effect of Sintering Temperature on the Mechanism of Metal Composite and Self Toughing and Toughening Si₃N₄ Ceramics Coupling

Abstract:

Fe-Mo/Si3N4 cermet powers are prepared by heterogeneous precipitation-thermal reduction process and sintered on normal pressure with Y2O3-MgO additives.The effect of sintering temperature on the phase composition, microstructure and mechanical properties are discussed. Result of study indicates: the rise of sintering temperature is beneficial to retention the metal phase and the generation of β-Si3N4 whisker. At the temperature of 1650°C, Y-Mg-Si-O-N glass phase is generated, At the temperature of 1700°C, whiskers-like β-Si3N4, good wettability phases on Si3N4 surface, and high toughness Fe phase appeared in Fe-Mo/Si3N4 cermets. It can effectively better the microstructures of Fe-Mo/Si3N4 cermets, and contribute to improve the material mechanical perperties. When the temperature rise to 1750°C, the maximum particle MoSi2 can destroy the microscopic structure, and decreases the density and mechanical properties of ceramics fast. The optimum sintering temperature is therefore about 1700°C.
