Data from: Ultra-uniform, strong and ductile 3D printed titanium alloy through bifunctional alloy design

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