Description	Creep in an Al-8.5Fe-1.3V-1.7Si (8009Al type) alloy dispersion strengthened with fine Al12(Fe,V)3Si phase particles and reinforced with alumina short fibres ů Composite in the following ů is investigated at temperatures 648, 698 and 748 K. The results are compared with those obtained for the composite matrix 8009Al alloy (Alloy in the following) at the same temperatures. Both, the Alloy and the Composite, exhibit true threshold creep behaviour; the true threshold stress decreases rather strongly with increasing temperature. However, independently of temperature, it is about twice as high in the Composite than in the Alloy. This is explained employing the concept of the load transfer effect in the true threshold creep behaviour. The minimum creep strain rate in both the Alloy and the Composite is controlled by the lattice self-diffusion in the matrix. The true stress exponent of minimum creep strain rate in the Composite as well as in the Alloy is very close to 5. The results show that rather dramatic Creep in an Al-8.5Fe-1.3V-1.7Si (8009Al type) alloy dispersion strengthened with fine Al12(Fe,V)3Si phase particles and reinforced with alumina short fibres ů Composite in the following ů is investigated at temperatures 648, 698 and 748 K.
