Abstract
Forged welded (damascus) steels are produced by traditional methods and mostly used in the design of decorative tools. These steels are well-known for their good mechanical properties. The process for making forged welded (damascus) steel consists of stacking alternating sheets of different kinds of steel on top of each other and then forge welding them together. In this study, the steels 1075 and 15N20 were used for the forging and folding procedure. The effect of fold numbers on the microstructure and mechanical behavior were investigated. The steel consisted of both materials, 54 and 250 layers, respectively, produced by forge welding. The pattern layers are homogeneous and regular, but after the process sections with up to 54 pattern layers were irregular. Steel 1075 has a pearlitic microstructure, while steel 15N20 has a ferritic microstructure. The impact toughness and tensile strength of the folded steels improved with increasing the number of folds.
Kurzfassung
Schmiedegeschweißte Damaszener Stähle werden nach traditionellen Verfahren hergestellt und überwiegend für die Herstellung dekorativer Werkzeuge genutzt. Diese Stähle sind sehr bekannt für ihre guten mechanischen Eigenschaften. Der Prozess für die Herstellung von Schmiedeschweißungen bzw. Damaszener Stählen besteht aus dem Aufeinanderstapeln verschiedener Bleche unterschiedlicher Art und dem anschließenden Zusammenschmiedeschweißen. Für die diesem Beitrag zugrunde liegende Studie wurden die Stähle 1075 und 15N20 für den entsprechenden Schmied- und Faltprozess verwendet. Es wurden die Auswirkungen der Anzahl der Faltungen auf die Mikrostruktur und das mechanische Verhalten untersucht. Der so entstandene Stahl bestand aus beiden Materialien, 54 bzw. 250 Lagen, die durch Schmiedeschweißen hergestellt wurden. Die Musterlagen waren homogen und gleichmäßig verteilt, aber nach dem Schmiedeschweißen gab es Bereiche mit bis zu 54 Lagen, die ungleichmäßig waren. Der gefaltete Stahl 1075 hat eine perlitische Mikrostruktur, während der Stahl 15N20 ein ferritisches Gefüge aufweist. Die Kerbschlagzähigkeit und die Zugfestigkeit der gefalteten Stähle verbesserte sich mit zunehmender Anzahl von Faltungen.
