Abstract
Processing maps make it possible to predict the formability of alloys in a simple way. These processing maps are widely used by scientists and engineers as seen in the large amount of publications in the last decades. Yet, in the last years, some publications called into question the principles of the model used for calculating processing maps. Therefore, the goal of this study is to analyse the applicability and the meaning of the processing maps.
Zusammenfassung
„Processing maps“ bieten eine Möglichkeit, die Effizienz der Gefügeänderung sowie Instabilitäten, welche sich während eines Umformprozesses bilden, darzustellen. Diese „processing maps“ werden von vielen Forschern und von der Industrie verwendet, was sich in zahlreichen Veröffentlichungen wiederspiegelt. Demgegenüber wurden in den letzten Jahren einige Kontroversen bezüglich der thermodynamischen Grundlagen und deren Anwendung publiziert. Infolgedessen ergab sich das Ziel der vorliegenden Arbeit, das Konzept der „processing maps“ zu untersuchen.
