Commercial maraging alloys provide high strength and toughness by traditional precipitation strengthening mechanism. Here, the authors demonstrate a new strategy involving deformable precipitates and their dynamic phase transformation resulting in a twofold enhancement of strength and ductility.

Precipitation hardening, used as an effective strengthening strategy in various alloy systems, has been usually achieved by coherent precipitates. Here, the authors develop ultrastrong ductile alloys employing structurally dissimilar semicoherent precipitates by shear band-driven precipitation.

Unlike diffusion-mediated chemical short-range orders (SROs) in multi-principal element alloys, diffusionless SROs and their impact on alloys have been elusive. Here, the authors show the formation of strain-induced SROs by crystalline lattice defects, upon external loading at 77 K.

Strong and ductile materials with resistance to both corrosion and hydrogen embrittlement remain rare and yet are essential for hydrogen-propelled industries. Here, the authors show that a CoNiV medium-entropy alloy with face-centered cubic structure fulfils all the above criteria.
