Description
Summary:The effect of crystallographic texture on the mechanical failure characteristics of a low-carbon steel was investigated. The technique adopted was the direction of propagation of the main crack in impact bend tests. The steel was produced by control rolling technology. The effects of plastic deformation on the texture of fracture surface layer during impact bend testing were tested by the corresponding inverse pole figures. For low-carbon low-alloy steels the crystallographic texture and its heterogeneity lead to the anisotropy of impact toughness. The crystallographic texture determines the direction of propagation of failure and fractographic special features of fracture surfaces in crack propagation.
