摘要：

We propose a numerical model for the evaluation of the influence of hydrogen on the subcritical growth of high-temperature creep cracks in metallic materials. The model is based on the first law of thermodynamics specifying the energy balance and the rates of changes in the energy components in a metallic body weakened by a macrocrack and subjected to the action of long-term static tension, high-temperature field, and hydrogen-containing media.
