Hydrogen influence on fracture of sheet carbon steel
Source abstract
Abstract
Results of the researches of hydrogen influence on fracture of 65Γ sheet spring steel by several methods are presented. The distribution of deformation and topography of a hollow in front of the crack tip is determined, the stress intensity factor is calculated, fractographic analysis of a fracture surface and metallographic analysis of the morphology of crack distribution are carried out. The decrease of operation characteristics of the material as a result of hydrogen influence which becomes apparent in localization of plastic deformations and intensive delamination on the layers of rolling is established.
