US Army Directive 2019-29 ("Enabling Readiness and Modernization through Advanced Manufacturing") envisions advanced manufacturing transforming battlefield logistics through on-demand fabrication of parts close to the point of need [1]. Towards this end goal, the Development Command - Army Research Laboratory (DEVCOM-ARL) is researching technologies that will make it possible for the warfighter to manufacture and/or repair components at the point of need with scrap materials on-hand, thus increasing operational readiness while reducing the military logistics footprint. The objective of this project was to show a proof-of-concept of additively manufacturing metal powder that was gas atomized in a Mobile Foundry housed within a shipping container from scrap rolled homogeneous armor (RHA) steel. The resultant alloy powder was subjected to laser powder bed fusion (LPBF), for builds that were tested metallurgically and ballistically. Cursory results showed that the additive manufactured builds from powder made from recycled RHA had a martensitic structure as stress-relieved, exhibited excellent mechanical properties, and improved ballistic properties versus this alloy in the wrought condition.
