Medium carbon steel prior to subjecting severe plastic deformation was thermomechanically treated in order to modified the initial grain size and morphology of cementite particles. The further structure modification of the steel was obtained during the equal channel angular pressing at increased temperature using the effective strain 3. The thermal stability qnd mechanical properties of the deformed steel were related to ultrafine grained structure development.

Štruktúra stredneuhlíkovej ocele bola spracovaná pred aplikáciou extrémnej deformácie s využitím kanálového pretláčania pomocou aplikácie temomechanického spracovania. Výsledkom a cieľom tohto spracovania bolo získanie jemnejšej štruktúry ocele s modifikovaným cementitom pred následnou aplikáciou extrémnej deformácie. Stabilita štruktúry vytvorenej ultrajemnej bola overená v podmienkach zvýšenej teplote extrémnej deformácie.
