摘要

Tensile tests of the alloyed 60S2A spring steel were carried out under the action of gaseous hydrogen with increased parameters: temperature 400 °C, and pressure 6 MPa. The true fracture diagrams of 60S2A steel were plotted for different hydrogen charging times. The optical-digital image correlation method of the sample surface and special software were used to determine the value of local deformation. It was established that fracture stresses and strains decrease linearly with increasing hydrogenation time.
