Crack/particle interactions in alumina/silicon carbide nanocomposites have been investigated by scanning electron microscopy and transmission electron microscopy, with cracks induced by Vickers microindentation. Intergranular cracks are frequently de

Polycrystalline aluminas of tailored composition and grain size, prepared using liquid-phase sintering aids based on the Al2O3-CaO-SiO2 and Al2O3-MgO-SiO2 systems, have been indented at loads close to their critical fracture limit P*, using closely s

Designing with Structural Ceramics
The last 30 years have seen a steady development in the range of ceramic materials with potential for high temperature engineering applications: in the 60s, self-bonded silicon carbide and reaction-bonded silicon nitride; in the 70s, improved alumina

A review of understanding of the statistical variations in strength in terms of microstructural features shows that the situation is highly complex. Models will require a considerable increase in sophistication before reliable predictions of strength

The tensile failure strength of ceramic composites can be measured by tests in bending or in tension, but care must be exercised over the experimental conditions. The strength values obtained are dependent on the test method and specimen size. It is

There has been a steady development and use of fracture mechanics, for describing the strength of brittle materials, ever since its inception by Griffith (1920). Materials considered include glass, ceramics, cement, brittle polymers, brittle metals,

Research was conducted to measure the strength and its variability in polycrystalline alumina with a wide variety of high-density arrays of flaws. The flaw arrays were produced by grit-blasting the surface, processing samples with small (10 μm diame
