Nanoparticle functionalization technique solves this problem by decorating high-strength unweldable alloy powders with specially selected nanoparticles.

“The way metallurgy used to be done was by farming the periodic table for alloying elements and testing mostly with trial and error. The point of using informatics software was to do a selective approach to the nucleation theory we knew to find the materials with the exact properties we needed.

Once we told them what to look for, their big data analysis narrowed the field of available materials from hundreds of thousands to a select few. We went from a haystack to a handful of possible needles.”

 

 

This opens up a topic for discussion regarding ways to recycle used additive metal powders that have become contaminated by sputtering and oxidation during use. Reprocessing powders to take advantage of this discovery may present a cost effective to improve materials normally considered unusable in advanced additive manufacturing.
