Ultrahigh strength enabled by dual-scale L12 precipitation and back-stress strengthening in an LPBF-fabricated (CoCrNi)94Al3Ti3 medium-entropy alloy

Simultaneously achieving ultrahigh strength and useful tensile ductility in precipitation-strengthened medium-entropy alloys requires control over not only precipitate characteristics but also the recovery and recrystallization of metastable additively manufactured microstructure...
