摘要：

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 delta-phase in the Cu-13.5 at. % In alloy partially dissolved and additionally enriched the Cu(In) solid solution. (C) 2014 Elsevier B.V. All rights reserved.
