Safety-related parts and components from metastable austenitic steel, such as pipes in light water reactors of nuclear power plants, are subjected to certain operational thermal, mechanical and medial loads, which can reduce their lifetime considerably. The aim of the research project is a process-oriented analysis of different fatigue mechanisms by means of various non-destructive testing and electrochemical measurement techniques to develop a design concept for determining the maximum service life of fatigue and corrosion fatigue stressed materials and components.

Duration: 2017 until 2023
