Titanium alloy Ti5553 (Ti-5Al-5Mo-5V-3Cr) is an excellent candidate for structural applications and additive manufacturing processes. Ti5553 is a heat treatable metastable beta titanium-alloy desirable for structural applications due to the high strength and low density. This relatively new β-stabilized alloy provides strength, ductility, fatigue resistance, and toughness advantages over other alloys. Work described here is part of a larger effort to develop strength models across strain rates for additively manufactured materials of interest to the NNSA complex. Electron Backscatter Diffraction characterization of Ti5553 microstructures produced powder bed fusion are used to study the impact of heat treatment on microstructure, mechanical properties, and dynamic performance. The difference in material response to deformation is discussed in the context of morphological and textural differences in as-built, β-solution treated, and β-solution treated and aged material. Development of damage under dynamic testing conditions is also discussed in relation to microstructural differences among these material flavors.
