Abstract

Tensile tests of the alloyed 60S2А spring steel were carried out under the action of gaseous hydrogen of increased parameters: temperature 400°С and pressure 6 MPa. True fracture diagrams of 60S2А steel were constructed for different hydrogenation time. To determine the value of local deformation, the method of optical-digital correlation of images on the surface of the sample and special software were used. It was established that with increasing hydrogenation time, the destructive stresses and deformations decrease according to a linear law.
