Vliv tepelného zpracování na strukturu a mechanické vlastnosti materiálů

Abstract

The aim of the bachelor's work was to show the effect of annealing modes at 810 and 850°C temperature in a pilot plant laboratory for strips rolled in operation. Heat treatment influence on mechanical properties and microstructure in comparison with a condition after hot rolling was compared. The theoretical part of the bachelor's work describes the particular methods of heat treatment with the influence upon material mechanical properties and microstructure. The practical part of the work presents and compares the real microstructure and the obtained mechanical properties of the samples made of 28Mn6 grade steel strips of 6mm thickness immediately after hot rolling and after normalizing at 810 and 850°C temperature with a specific heating period.
