Shock compression and spall of additively manufactured Ti-5553 alloy

The advent of additive manufacturing (AM) has opened a wide range of possibilities for producing materials and parts using AM techniques that require much less time and cost than traditional manufacturing techniques. One alloy of interest is Ti5553 (Ti-5Al-5Mo-5V-3Cr). We have recently conducted shock compression and spall experiments on Ti5553 produced by an AM process and subjected to a series of heat treatments to cause varying amounts of the as-manufactured β-phase to convert to the α-phase. The results of these experiments and accompanying ambient pressure measurements indicate significant anisotropy in the as-manufactured material that decreases with subsequent heat treatment. The results of our experiments will be discussed in the context of previously published studies on this alloy.
