ABSTRACT An ultra‐high as‐deposited tensile strength of 1408 MPa—the highest reported value for laser‐directed energy deposition (L‐DED) fabricated Ti2AlNb alloy—is achieved in this study. The as‐deposited microstructure consists of coarse B2 grains with a high density of fine acicular O phase precipitates within the grains, along with a brittle α2 ...

Geometry‐Encoded Programmable Mechanics in Single‐Material Dual‐Phase Metamaterials
Inspired by the unique soft‐hard heterogeneous architecture of nacre, this study proposes a novel class of dual‐phase (DP) metamaterials. The DP metamaterials exhibit programmable nonlinear mechanical responses, tailored failure processes, and enhanced energy absorption by systematically varying the spatial coding patterns of soft‐hard unit cells ...

X‐ray computed tomography reveals how process‐induced defects evolve from green to sintered states in Fused Filament Fabrication (FFF)‐manufactured 17‐4PH stainless steel. Internal porosity, weakest cross‐sections, and fracture locations show strong correlation with tensile performance, demonstrating the potential of computed tomography (CT)‐based ...

CORROSION EVALUATION OF LPBF-MANUFACTURED DUPLEX STAINLESS STEEL
In this study, the effect of as built and heat-treated additively manufactured 2507 super duplex stainless steel (SDSS) on electrochemical corrosion performance was examined. The corrosion was studied by Tafel polarization and electrochemical impedance spectroscopy (EIS) methods in a 3.5% NaCl solution.
