Description	The creep behaviour of an Al-8.5Fe-1.3V-1.7Si-15SiCp composite in two temperature intervals, namely 623 to 723 K and 773 to 823 K is investigated using the isothermal constant stress creep test technique. The measured minimum creep strain rates cover six to seven orders of magnitude. Occasionally, this creep behaviour is compared with that of an unreinforced (matrix) Al-8.5Fe-1.3V-1.7Si (8009Al type) alloy. For the temperature interval 623 to 723 K the true threshold creep behaviour is characteristic. The true threshold stress decreases with increasing temperature more strongly than the shear modulus and is higher in the composite than in the matrix alloy. With the strong temperature dependence of the true threshold stress, extremely high values of the apparent activation energy and the apparent stress exponent are associated. However, the minimum creep strain rate is matrix lattice diffusion controlled and depends on the fifth power of the effective stress ( is the applied stress).
