Furthermore, cold rolling tests and microstructural analysis have been realized in order to allow a detailed discussion of the obtained SFE-values. The results of this Investigation indicate that the stacking fault energy of the austenite phase within the duplex stainless steel Is lower than those of single-phase austenitic stainless steels. This is justified by the chemical composition; mainly by the Cr and Ni alloying contents. Nevertheless, work hardening of the austenite during cold deformation is not as accentuated as expected by the low SFE-values, because at higher deformation levels the deformation mainly occurs within the ferrite phase. Abstractde Mit Hilfe transmissionselektronenmikroskopischer Untersuchungen wurde die Stapelfehlerenergie innerhalb der Austenitphase des ferritisch-austenitischen Duplex-Stahls W.-Nr.: 1.4462 ermittelt. Um eine detaillierte Diskussion der Meßwerte durchführen zu können, wurden Kaltwalzversuche und metallographische Gefügeanalysen durchgeführt. Die Ergebnisse dieser Arbeit weisen auf eine im Vergleich zu einphasigen nichtrostenden austenitischen Stählen geringere Stapelfehlerenergie der untersuchten Austenitphase hin. Die Erklärung liegt In der chemischen Zusammensetzung dieser Austenitphase; hauptsächlich in deren Chrom- und Nickelgehalte. Daß dennoch die Verfestigungsrate dieser Austenitphase während der Kaltumformung des Duplex-Verbundes niedriger ist als anhand des niedrigen SFE-Wertes vermutet, liegt an der zunehmenden Konzentration der Verformung Innerhalb der Ferritphase bei höheren Umformgraden.
