Creep experiments performed at low stresses for an alumina-SiC whisker-reinforced composite containing 6 vol.% whiskers agree with the deformation model presented schematically in the deformation map. This is, below the percolation limit creep is controlled by diffusional flow. The stress exponent evolution is consistent with the predictions that the flow under low stress is controlled by pure diffusion while under high stress, flow is controlled by accommodated grain-boundary sliding.
