Ultrauniform, strong, and ductile 3D-printed titanium alloy through bifunctional alloy design

Science, Journal Year: 2024, Volume and Issue: 383(6683), P. 639 - 645

Published: Feb. 8, 2024

Coarse columnar grains and heterogeneously distributed phases commonly form in metallic alloys produced by three-dimensional (3D) printing are often considered undesirable because they can impart nonuniform inferior mechanical properties. We demonstrate a design strategy to unlock consistent enhanced properties directly from 3D printing. Using Ti-5Al-5Mo-5V-3Cr as model alloy, we show that adding molybdenum (Mo) nanoparticles promotes grain refinement during solidification suppresses the formation of phase heterogeneities solid-state thermal cycling. The microstructural change bifunctional additive results uniform simultaneous enhancement both strength ductility. how this alloy be modified single component address unfavorable microstructures, providing pathway achieve desirable characteristics
