Wire-arc directed energy deposition of advanced titanium alloys

Description

Wire-arc directed energy deposition has been under development in the past years and is presently established for various applications and materials. Among these, titanium alloys have been in focus since resource and cost savings are very much pronounced for this alloy class. In comparison to conventional processing technologies, wire-arc directed energy deposition is capable of reducing the buy-to-fly ratio significantly from typically above 5 to below 2. Ti-6Al-4V is the most widely used alloy in general and, thus, the most widely studied alloy for wire-arc directed energy deposition. Numerous reports are available outlining the processability and the resultant ranges of properties. However, certain applications require higher mechanical properties either at room temperature or in the elevated temperature regimes. Therefore, this presentation reports on findings in three different alloy systems, namely Ti-10V-2Fe-3Al – a near-β alloy, Ti-15V-3Cr-3Sn-3Al – a metastable β alloy, and Ti-6Al-2Sn-4Zr-2Mo – a near-α alloy. Each of these alloys was deposited using wire-arc directed energy deposition in combination with different post-deposition heat treatments. The presentation will expand upon their processing behaviour and obtained microstructural characteristics and mechanical properties and outline potentials for future applications.
