Study of Microstructure Formation of Carbon Steel Under High-Speed and Multicycle Hot Plastic Compressive Deformation Using A Gleeble 3500 Unit

  • Published:
Metal Science and Heat Treatment Aims and scope

Features of deformation regimes and mechanisms of microstructure formation in low-carbon steel 20 are studied using high-speed and multicycle hot plastic deformation methods in a Gleeble 3500 unit. Energy-force and temperature-speed regimes are established providing preparation of an ultrafine-grained structure with grain size of 150 – 1250 nm, similar to that achieved with higher degrees of cold plastic deformation. Specimen microhardness is determined.
