摘要：
Creep data of five dispersion-strengthened aluminum materials were analyzed by means of well known diffusion controlled slip creep mechanisms incorporating a threshold stress. It is shown that the threshold stress that has to be introduced into such mechanisms to fit the creep data is strongly temperature dependent. Such temperature dependence cannot be explained by the various models used in the literature.
