| Abstract: | A theoretical and experimental approach to prognosis of fatigue crack growth behavior and determination of the remaining resource of elements of constructions under the influence of temperature and hydrogen is discussed in the paper. Kinetic fatigue fracture diagrams of austenitic steel of 10Kh15N27T3V2MR were experimentally built and analytically described at different temperatures in a neutral environment and in hydrogen. The threshold and critical values of the stress intensity factor (SIF) were found. The durability of a turbine disk was evaluated. It is found that hydrogen reduced the remaining resource of this structural element almost by 2-3 times. |
