Laser additive manufactured Ti-6Al-4V parts have been tested by Lockheed Martin Aeronautics. This research effort has been geared towards comparing LAM Ti-6-4 with other titanium product forms, demonstrating that LAM airframe parts can be fabricated, and compiling a LAM mechanical properties database. This effort has been primarily funded through the Metals Affordability Initiative. Acquired mechanical properties consist of tensile, shear, bearing, compression, fracture toughness, fatigue, crack growth, and stress corrosion cracking. These results will be summarized along with discussions on what steps remain to make LAM a viable process within the aerospace community.
