Cyclic Flexural Deformation of Thick Steel Sheet

Аннотация

The influence of cyclic flexural deformation of thick low-alloy and carbon steel sheet on its structure and mechanical properties is investigated over a broad temperature range. In plastic flexure, the deformational amplitude is 1–6%. Permissible parameter ranges corresponding to the best mechanical properties of the steel, without irreversible structural damage, are selected. Strengthening treatment for thick steel sheet is developed, and permissible parameter ranges are proposed.
