A high-temperature nanostructured Cu-Ta-Li alloy with complexion-stabilized precipitates

{{output}}
We present a bulk nanocrystalline copper alloy that can operate at near-melting temperatures with minimal coarsening and creep deformation. The thermal stability of the Cu-3Ta-0.5Li atomic % (at %) alloy is attributed to coherent, ordered L12 Cu3Li precipitate... ...
