Description	A previous investigation of creep behavior in an Al-8.5Fe-1.3V-1.7Si (8009AI type) alloy processed by rapid solidification and strengthened with small incoherent Al-12 (Fe,V)(3)Si phase particles, is extended to temperatures ranging from 773 to 923 K using the isothermal constant-stress-creep test technique. While in the temperature interval 623-723 K the creep behavior of the alloy is associated with the true threshold stress, at 773-923 K the true threshold stress is absent: the apparent stress exponent of minimum creep strain rate, m,, decreases with decreasing applied stress. Assuming a temperature independent value of the relaxation factor k(R) characterizing the strength of attractive dislocation/Al-12(Fe,V)(3)Si particle interaction, an attempt is made to interpret the minimum creep strain rate behavior in terms of the Rosler-Arzt model. The structure factor C following from the fitting procedure differs from that calculated from the structure data by a factor in average equal to 60.
