Material properties of copper alloys containing arsenic, antimony, and bismuthJunk, Margrit 11 July 2009 (has links) (PDF)
This work deals with Early Bronze Age ingot torques, their composition, and material properties. The aim was to decide whether and how a choice of materials by composition or properties was possible during the Early Bronze Age. Early Bronze Age ingot torques were analysed and artefacts from several hoard finds and working stages were investigated metallographically. On the basis of these data the production technology was reconstructed. For the determination of mechanical and technological properties, reference alloys were produced and investigated. The production process was simulated by forging experiments. The investigations revealed that ingot torques were produced by a standardised technology, independent of their composition. The results of the material testing show that it is possible to distinguish the composition of the Early Bronze Age alloys by their mechanical and technological properties.
