The influence of structure, sensitization and corrosion on the fatigue properties of austenitic steel

Abstract

The article will be focused on examining and comparing the influence of structure, sensitization and corrosion on the fatigue properties of austenitic stainless steel. The methodology of the experiment includes fatigue tests of samples attacked by intercrystalline corrosion. Therefore, the test samples were subjected to heat treatment for sensitization. Then these samples were subjected to long-term exposure in an aggressive corrosion solution. Experiments deal with microstructural material analysis, fractographic analysis, mechanical and fatigue tests.
