AuCuNiPdPt as a benchmark for high entropy alloys — •Jens Freudenberger1,2, Felix Thiel1,3, Alexander Kauffmann4, Martin Heilmaier4, and Kornelius Nielsch1,31IFW Dresden — 2TU Bergakademie Freiberg — 3TU Dresden — 4Karlsruhe Institut für Technologie

The high entropy alloy AuCuNiPdPt appears single-phase and with the Cu-type structure. Additionally, non-stoichiometric alloys made from any of these elements with arbitary composition also crystallise single-phase with the Cu-type structure. Therefore, these alloys can be used to separate the material behaviour of the HEAs cleanly from that of single phase conventional alloys and to identify which issues are special for HEAs leading to their peculiar properties. The present study presents the mechanical behaviour and a microstructure analysis of AuCuNiPdPt.
