    • On the Temperature-Dependence of Deformation-Induced Martensite Formation in AISI 304L Type Steel
    Authors: Egels, G.; Bussmann, M.; Benito, S.;  Advisor: -;  Co-Author: - (2023)

    In this study, the deformation-induced α-martensite formation in AISI 304L steel was investigated in the temperature range between 75 °C and − 196 °C in the light of the temperature-dependence of hydrogen embrittlement phenomena. For this purpose, tensile tests with in-situ and ex-situ magnetic measurement of the α-martensite volume content as a function of plastic strain were carried out. In addition, a theoretical assessment of the temperature-dependence of the austenite stability was undertaken, evaluating chemical and non-chemical driving force contributions to the martensitic γ → α transformation as proposed by Ghosh and Olson.
