OSTI ID:4653096
The phenomena associated with the fracture of ceramic oxides are studied. The nature of strength and failure in MgO and Al/sub 2/O/sub 3/ is described for various environments and temperatures. Topics covered include: strain effects in bending, internal friction in mono- and polycrystalline ceramics, surface and fracture energy of precracked plates, fracture mechanisms, effects of impurities on the porosity of ceramics, high-temperature deformation, dislocation studies in polycrystalline ceramic materials, effects of polyaxial stresses on fracture behavior, influence of surface treatment on strength of oxides, residual stresses in oxide ceramics, effects of grain size and porosity on transverse bend strength, and hot extrusion of alumina and magnesia.
