Tensile creep rupture behavior of alumina-based polycrystalline oxide fibers
Creators
Description
Creep rupture tests have been performed on single filaments of 'Fiber FP' Al2O3 at 1150-1250 C and 'PRD-166' Al2O3-ZrO2 at 1150-1300 C. It is noted that, under similar conditions of applied stress and temperature, Al2O3 fiber creep rates were up to four times greater than those of Al2O3-ZrO2. Experimental creep rates were found to be slower than those calculated via Coble's (1963) constitutive relationship and faster than the rate calculated with the interface reaction-controlled relation of Burton (1972). The creep of these fibers therefore appears to be controlled by an interface reaction-limited grain-boundary diffusional process. 12 refs
