"Creep in an Al-8.5Fe-1.3V-1.7Si (8009Al type) alloy dispersion strengthened with fine Al-12(Fe,V)(3)Si phase particles at temperatures 798-848 K is not associated with a true threshold and the same holds for the Alloy reinforced with alumina short fibres. While the true activation energy of creep in the Alloy is higher than the activation enthalpy of lattice self-diffusion in aluminium due to the energy of athermal detachment of dislocations from dispersed particles, this is not the case of the Composite. The true activation energy of creep in the latter is anomalously low and the creep behaviour cannot be described by the creep equation that holds for the Alloy, but contains the factor by which the flow stress in the dispersion strengthened matrix is reduced due to load transfer. Nevertheless, the creep strength of the Composite is, at the certain conditions at least, by a factor up to six orders of magnitude higher than that of the Alloy. This creep strength increment due to alumina short fibre rein" . . "42" .
