As Metal Additive Manufacturing (AM) continues to gain acceptance in aerospace and defense applications, the need for the production of high quality material with excellent, repeatable mechanical properties continues to increase. In aerospace, aluminum and titanium alloys are in high demand due to their high strength to weight ratio, resistance to oxidation and corrosion, and relative formability. Both aluminum and titanium alloys are in production in metal AM applications, but usage has generally been limited by a number of factors, including the lack of availability of alloys equivalent to common wrought or cast designations; knowledge of suitable heat-treatment and post-processing parameters; lack of industry standards; and ability to control process parameters to manufacture parts to a high process capability. This presentation will describe some of the recent advances in these areas, including new alloys, improved process controls, better heat treatments, and new standard methods for quality assurance. Applications able to take advantage of these improvements will be highlighted, as will future directions for these materials.
