Abstract

•High-pressure torsion of Cu–In alloys with negative mixing enthalpy has been studied.•Six homogenized alloys with 2.3 to 13.5 at. % In were investigated.•Cu(In) supersaturated solid solutions did not decompose.•Moreover, the precipitates of δ-phase in the Cu–13.5 at. % In alloy partially dissolved.

High-pressure torsion of six homogenized Cu–In alloys (2.3 to 13.5 at. % In) with negative mixing enthalpy has been studied. The torsion torque reached a steady-state after 1–2 anvil rotations. Differently to the alloys with positive mixing enthalpy, the Cu(In) solid solution did not decompose. Moreover, the precipitates of δ-phase in the Cu–13.5 at. % In alloy partially dissolved and additionally enriched the Cu(In) solid solution.
