Vliv vibračního zpracování na mechanické vlastnosti, strukturu a zbytková napětí svarů konstrukčních ocelí

Abstract

The master thesis within the study of Materials Engineering - Progressive Engineering Materials is focused on the research of the influence of vibration treatment on residual stresses, structure and mechanical properties in the weld area. The thesis compares the states of the materials S355J2+N and 15 128.5 without post-welding treatment, after vibration treatment and after stress relief annealing. The aim of the work is to determine whether the vibration treatment can replace the stress relief annealing.
