HRL Laboratories, LLC, continues its research push to advance the state of the art in additive manufacturing (AM) of high performance alloys. The HRL AM team’s new paper elucidates the fundamental physics behind HRL’s expertise, which enables significantly improved control of how 3D-printed metals melt and solidify. The paper, Grain refinement mechanisms in additively manufactured nano-functionalized aluminum, was published online in September 2020 ahead of the November print issue of the journal Acta Materialia.
HRL Laboratories has successfully demonstrated a scalable, water-based nanoassembly manufacturing technique with many possible uses, including growing powerful rare-earth-free magnets and infrared optical materials. The new method is a bench-top task and is scalable to industrial manufacturing volumes.
