The alloy was aged to achieve the combinations of strength and ductility. The strengthening mechanisms included transformation-induced plasticity, twinning-induced plasticity and precipitation strengthening. These multiple strengthening mechanisms can serve as a basis for alloy design and the improvement of the mechanical properties of alloys. (C) 2021 Acta Materialia Inc. Published by Elsevier Ltd.
