Current alloys used in Additive Manufacturing (AM) were originally designed to be processed via traditional metallurgy paths such as forging, and have different microstructures and properties when put through AM processes. Additionally, heat treating AM-built alloys according to standard industry practice causes material performance issues.

New material chemistries designed specifically for AM processing and the subsequent thermal processing steps tailored for the unique microstructures must be developed to enable AM components to reach enhanced performance.

Integrated Computational Materials Engineering technologies allows for the optimization of legacy alloys and design of entirely new alloys tailored specifically for AM, and also to optimize post-build heat treatments across a variety of alloy systems including Al, Ti, Ni, Cu, W, Fe and stainless steel.

This talk will provide technical updates and component design opportunities based on several ongoing projects where properties are being demonstrated in powder and wire AM, including: (i) a Ti new alloy with increased strength over traditional Ti-6-4, (ii) high performance Ferrium C64 gear steel for gear applications (iii) new, printable, high strength aluminum alloys for use at room temperature and temperatures up to 325°C and (iv) stainless steel and ultra high strength steels.
