摘要	The creep behavior of an Al-8.5Fe-1.3V-1.7Si composite reinforced with beta-Si3N4 whiskers has been investigated at temperatures of 773 and 823 K. The results are characterized by a high stress exponent and high apparent creep activation energy. The creep data can be interpreted on the basis of the incorporation of a threshold stress and a load-transfer coefficient into the power-law creep equation. A good correlation exists between the normalized creep rate and normalized effective stress which demonstrates that the creep behavior of both the alloy and the composite is controlled by the matrix lattice self-diffusion in aluminum.
