Symposium Alloy Behavior and Design Across Length-Scales: An SMD Symposium Honoring Easo George
Presentation Title Solid Solution Hardening Effects on Thermal Stability and Mechanical Properties of Nanostructured Ni-enriched CrMnFeCoNi High Entropy Alloys
Author(s) Tom Keil, Enrico Bruder, Karsten Durst
On-Site Speaker (Planned) Karsten Durst
Abstract Scope This work focuses on the saturation grain size as well as grain growth and decomposition tendencies of Ni-enriched subsystems of the CrMnFeCoNi Cantor alloy (Ni20, Ni60, Ni92 and Ni100)) after heat treatment for RT to 900C with an emphasis on a transition from dilute solid solutions to high entropy alloys. The influence of solutes on the defect storage, microstructural stability and mechanical properties studied via Nanoindention will be discussed. After High Pressure Torsion saturation grain sizes in the nanometer regime are found for the HEA compositions, whereas the grain refinement scales with solid solution strengthening contribution. All alloys exhibit a two-stage coarsening behavior with marginal grain growth below a certain temperature and typical diffusion driven growth above, followed by decomposition tendencies for the HEA type alloys. Annealed alloys show a pronounced change in the pile-up behavior around nanoindentations, indicating a strong change in the work hardening behavior (Hardening via annealing).
