Abstract:
The room temperature mechanical properties of Al2O3-SiC hot pressedcomposites containing 5-25 vol.% of three different SiC powders, in the shape of fine particles, platelets and short fibres, have been investigated. X-ray diffraction, optical microscopy and SEM were used for phase analysis and microstructural examination of the samples. The mechanical properties were related to the microstructural examination of the composites. The composite reinforced with 20 vol.% SiC platelet revealed the highest fracture toughness, 6.4 MPa.m"1"/2, and bending strength, 517 MPa. 2 figs., 3 tabs., 6 refs.
