Corrosion behavior depending on different stress conditions of metastable austenitic stainless steels

authored by: Kathrin Voges-Schwieger, Peter Wilk, Bernd Arno Behrens
Abstract: This paper deals with current results of investigations regarding martensitic phase transitions at temperatures well below room temperature. To characterize samples, the fractions of alpha'-martensite contents after the different tests are evaluated by means of eddy-current methods and metallographic examinations. Effects that lead to increasing corrosion resistance caused by martensite for those different test specimens, are assessed by means of Kesternich-tests according to DIN EN ISO 6988. As one result, the correlation between different martensite contents and their respective corrosion resistance in sulphur dioxide solutions (artificial industrial atmosphere) under consideration of different stress conditions will be presented. Additional results from further analyses depending on stress conditions e.g. tensile stress, plane strain stress, deep drawing or stretch forming will be introduced.
