Harnessing Bifunctional Nitrogen‐Dislocation Interactions for a Record Ultra‐Strong‐and‐Ductile Duplex Titanium Alloy

Harnessing Bifunctional Nitrogen‐Dislocation Interactions for a Record Ultra‐Strong‐and‐Ductile Duplex Titanium Alloy

Abstract Duplex (α+β) Ti alloys often manifest limited uniform elongation (εu) mainly originating from the lack of <c+a> dislocations for insufficient work hardening capability and semi‐coherent α/β interfaces for strain incompatibility. The strength–ductility trade‐off of duplex Ti alloys is...
