A New Ordered Transformation‐Induced Plasticity Enables Exceptional Strength and Ductility in a B2 Medium‐Entropy Alloy

Advanced Science, EarlyView.
A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Strengthening Constitutive Motifs in Isotropic Fibrous Hydrogel for Exceptional Damage Resistance

Advanced Science, EarlyView.
An orientation‐free strategy is reported for fabricating damage‐resistant hydrogels by strengthening constitutive motifs in isotropic fibrous (IF) networks. Through nonsolvent quenching followed by salting‐out, IF networks are generated and their multiscale constituents are subsequently reinforced, yielding dense and crystalline isotropic nanofiber ...
