Effect of Severe Plastic Deformation and Hardening on the Properties and Failure Mechanisms of Constructional Steel


Article Preview

The influence of severe plastic deformation on structural materials has been actively studied in recent years. Undoubtedly is the positive influence of this method on strength characteristics of materials. In addition, it is very interesting to influence of the severe plastic deformation on the mechanisms of fracture. One of the most common methods of severe plastic deformation is equal-channel angular pressing (ECAP). In this paper, the influence of different modes of ECAP on the strength of structural steel was studied. Also, the destruction of steel at different test temperatures was studied in detail. It is shown that the ECAP increases the strength of steel almost twice, but the plasticity of steel is reduced, which leads to fragility. Quenching can remove the negative impact of the ECAP on toughness of the steel and will increase the impact strength several times.
