Description	The steady-state creep rate increases with testing temperature according to the Arrhenius equation and its increase with applied stress is mostly described by the power law. Combining both these laws by simple multiplication, the most often used equation describing the dependence of steady-state creep rate on both the variables in common is obtained. This equation contains apparent activation energy and stress sensitivity parameter like constants but most measurements show their dependence on some of the variables. An equation respecting these experimental facts and simultaneously also based of the Arrhenius equation and the power law is derived and verified using some published results of creep tests. It can be presented geometrically by hyperbolic paraboloid. Resulting from this equation, the dependence of yield stress on temperature and strain rate and also an equation describing the relaxation curves are deduced.
