| Abstract Scope |
A longstanding goal of structural materials research has been the promotion of strength and ductility without compromising one for the other. Usually this requires the activation of multiple deformation mechanisms in parallel and/or in series – mechanisms such as precipitation strengthening, deformation-induced twinning and phase transformation induced plasticity. High-entropy alloys (HEAs) with the face-centered cubic (fcc) structure can exhibit extensive tensile ductility and excellent toughness, but their room-temperature strength tends to be low. In this presentation, we will demonstrate strategies that utilize computational thermodynamics and kinetics to design alloys with multiple deformation mechanisms for sustainable work hardening, thereby to simultaneously achieve higher strength and better ductility. |
