✦ Synopsis

The creep and creep rupture behaviour of a phenolic-alumina particulate composite was determined in an aqueous environment. Flexural creep tests were carried out in which the loading-point displacement was measured as a function of applied stress and time. The material exhibits power-law creep behaviour in which the steady-state creep rate is a power function of the initial applied elastic stress. The creep exponent was found to be 5.3. The creep rupture behaviour can be explained using a modified Monkman-Grant relationship which provides a failure criterion that is independent of applied stress and stress state.

Composites of alumina reinforced with SiC whiskers have been creep tested in bending and in compression at 1200-1400 Β°C in an air ambient. The flexural creep data follow a power law constitutive relation with two distinct stress exponents that depend on the level of applied stress. Crept specimens w

The sintering of particulate composites consisting of a polycrystalline zinc oxide matrix with 10 vol% zirconia inclusions of two different sizes (3 and 14 gm) was investigated at a constant heating rate of 4~ min -1 under an applied stress of ~ 300 kPa. The presence of the inclusions produced a dec
