The principle of affi ne similarity of the primary curves of deformation or fracture of a single family is used to formulate the hypothesis of a unique curve in application to long-time strength and models of longevity and models of longevity are analyzed using an exponential-power law representation. The possibilities of predicting the long-time strength of high-temperature steel and alloys on the basis of the longevity law introduced are checked on long-time experiments.
