Abstract
Creep test was carried out on solid solution aluminum alloys to study the effect of solute atoms on deformation behavior and creep property at high temperatures. Two kinds of aluminum alloys, A5083 and A6061 were tested. We obtained the experiment equation, t_f = λσ^<-m> for the relation between the applied stress and creep life. The exponent, m was constant independent of the temperature. For A6061 alloy, the contraction creep was observed at lower applied stress. The behavior was expected to be due to the interaction of solute atoms, Mg and Si.
