| Abstract: | It is experimentally established that air-tested samples of degraded material showed tooth flow that disappears for tests in hydrogen. The main feature inherent in the studied materials are metastable and presence of more or less pronounced time- and temperature-dependent processes of structural relaxation, which reduces the total free energy of a thermodynamic system. The values of fracture toughness minimize the square deviation of experimentally obtained values drift from the theoretical curve corresponding to the exponential relaxation function. |
| Description: | The extraction method and determined the content of active hydrogen diffusion in samples of steel 45, which undergoes an intensive selection during the first 6 h. after saturation (maximum concentration is 2.8 ppm) were improved. The residual hydrogen content was determined by infrared desorption of fusion of the sample. Tested in air samples from a degraded material showed tooth flow, which disappears for tests in hydrogen. |
