Abstract
An extension of a previously developed method for predicting creep and long-term strength is presented. The method is based on known information concerning the behavior of a pre-tested specimen (a leader specimen or prototype) under conditions of viscous material failure and is eventually generalized to the case of exposure to an aggressive environment—hydrogen charging of metallic specimens and structural components with varying degrees of introduced hydrogen. The advantages of the developed method over more complex known models are noted. Results of the calculation of creep and long-term strength for hydrogen-charged specimens made of VT6 alloy at a temperature of 600 ∘C are presented. The research results demonstrate that the developed method not only allows us to predict the creep and longterm strength curves but even enables to plan the optimal experiments to obtain a series of creep curves under constant stress.
