[EN] Se ha medido la resistencia a flexión de los compuestos cerámicos eutécticos Al2O3-ZrO2 (Y2O3) y Al2O3-Y3Al5O12 procesados por la técnica de fusión zonal asistida por láser en el intervalo de temperaturas de 25ºC a 1427ºC. Se ha investigado el efecto de la microestructura, de las tensiones residuales y de la temperatura sobre la resistencia a flexión y los mecanismos de fractura asociados para cada material.
[ES] The flexure strength of directionally-solidified Al2O3-ZrO2(Y2O3) and Al2O3-Y3Al5O12 eutectic ceramic composites processed by the laser-heating floating zone method was studied from 25ºC to 1427ºC. The effect of microstructure, residual stresses and temperature on the flexure strength and the associated fracture mechanisms was assessed for each material.
Este proyecto de investigación ha sido financiado por el Ministerio de Ciencia y Tecnología con cargo a los proyectos MAT2000-1533-C01 y C02 y MAT2003-06085-C03-01.
