Micromechanic of Al{sub 2}O{sub 3} matrix composites toughened by metallic phases
- Univ. di Trento, Mesiano (Italy). Dept. di Ingegneria dei Materiali
Ceramic materials toughened by dispersion of a ductile metallic phase can be a solution for high temperature applications where corrosion and mechanical resistance are requested in severe conditions. Alumina based composites are studied for this purpose from the micromechanic point of view; combining the microstructure characterization with numerical simulations a better study Dan design of these materials can be performed. Al{sub 2}O{sub 3} reinforced with Ni second phase composites were prepared and characterized by SEM, TEM and XRD techniques; the measured mechanical properties were compared with numerical simulation based on the microstructure analysis and the results can be used to design a better microstructure. In particular, using some microstructure characteristics as design parameters, the mechanical properties of the composite can be optimized by numerical simulations.
