Einfluss einer aufgeprägten Spannung auf die isotherme, perlitische und bainitische Umwandlung des Wälzlagerstahls 100Cr6

Abstract: Kurzfassung Eine optimale Simulation von Wärmebehandlungsprozessen setzt voraus, dass die notwendigen Stoffwerte zur Beschreibung der Phasentransformation zur Verfügung stehen. Während der Wärmebehandlung entstehen umwandlungs- und thermisch bedingte Spannungen, die das Umwandlungsverhalten beeinflussen. Das Zusammenwirken zwischen Phasenumwandlung und inneren Spannungen ist Gegenstand der vorliegenden Untersuchung. Für die isotherme, perlitische und bainitische Umwandlung des Wälzlagerstahls 10… Show more

“…For testing strategies of proposals we refer to [25]. The Greenwood-Johnson parameters j i depend approximately linearly on temperature and differ essentially in different PT [24]. Moreover, a slight dependence on stress and its direction can be observed [2].…”

“…Assuming that l does not depend on p, the right-hand side Formula (4) is independent of phase transformations. Often the elastic part is neglected, especially for a constant stress S during phase changes [14,15], e. g.…”

Again, the model is kept simple here, see [13,14] for more complex models, including back stress e.g., discussion and literature.…”
