| Abstract Scope |
The compositional complexity underlying high entropy alloys (HEAs) presents exciting opportunities for tuning properties, accompanied by significant complexity in their synthesis, processing, and recycling. Advances in synthesis and recycling pathways to reduce carbon emissions and energy are necessary to enable sustainable industrial use of HEAs. In this work, we propose a single-step reaction pathway to produce HEAs directly from oxide precursors by utilizing mechanochemical reactions from ball milling to trigger metallothermic reduction in a molten phase. The reduction mechanisms will be demonstrated in a binary oxide-metal system, accompanied by discussion of a variety of HEAs synthesized by this reaction pathway. This approach enables alloy synthesis with remarkably low energy consumption while unlocking new alloy design opportunities. |
