Vliv tepelného zpracování na deformaci výkovku z oceli 30MnB5

Abstract

the forging after quenching and tempering in water. Theoretical part of this Thesis is devoted to specifying characteristics of given steel. Then it is focused on the influence of the heat treatment and on previous technological operations, on their structure relating introduced stress that causes the deformation of the product. In the practical part I will aim at the specific forging of the steel 30MnB5 where it is not succeeded to keep the required flatness after heat treatment with using contemporary technologies. Analysing these methods, I will try to suggest and experimentally examine and find the solving of limiting the origin of deformation.
