Mechanical properties of the high-entropy alloy Au-Cu-Ni-Pd-Pt — •Felix Thiel1, Jens Freudenberger1,2, and Kornelius Nielsch1 — 1IFW Dresden, Helmholtzstr. 20, 01069, Dresden, Deutschland — 2TU Bergakademie Freiberg, Insitut für Werkstoffwissenschaft, Gustav-Zeuner-Str. 5, 09599, Freiberg, Deutschland
High Entropy Alloys (HEAs) show outstanding mechanical and physical properties, which would not have been expected upon their simple crystal structure and the fact that they are single phased. The Au-Cu-Ni-Pd-Pt system and their including subsystems show crystallization into the same Cu-type crystal structure within the whole concentration range. Therefore, this system is unique and particularly suitable to study the alloying effect on the properties within a large concentration range without the necessity of considering other phases. The present study shows the effect of alloying a multi-component solid solution on the properties of medium and high entropy alloys in this system. In particular, effects such as solid solution hardening and work hardening are assessed.
