The experimental material, dispersion strengthened aluminium with Al4C3 particles, was prepared by mechanical alloying of aluminium powder (<50 μm) with different types of carbon. Creep behaviour of the composite, based on aluminium matrix, reinforced by 4 vol% Al4C3, was studied at temperatures from 623 to 723 K by small punch testing with a constant force. The time dependence of the central deflection was registered and the minimum deflection rate was determined. The dependence of this quantity on the applied force can be described by a power function with relatively high value of the power. The dependence can be rationalized by an analysis in terms of the threshold concept. Analytical procedure for comparison of the threshold force in small punch experiments and threshold stress in conventional creep testing are given.
