Vlastnosti martenzitické antikorozní oceli před a po cyklickém zatěžování

Abstract

The main goal of this work is the analysis of stainless steel focused on martensitic stainless steel. Firstly, dividing and application of stainless steels and alloys are described in the work. Afterwards it is focused on cyclical and material tests. In the experimental part comparison of basic mechanical properties of martensitic stainless steel before and after cyclic loading was carried out, which proved that material was not strengthened after loading and only plasticity was increased. Metallographic evaluation of samples revealed fatigue crack which resulted from cyclic loading.
