Titanium and its alloys have exclusive usage as structural materials in many challenging aerospace, defense, and automotive applications because of their light weight, high corrosion resistance, and high strength at both room temperature and elevated temperatures. With microstructure refinement and design of structural hierarchy, further improvement can be achieved in strength to weight ratios, energy absorption, and thermal/vibrational damping. The present work entails titanium alloys fabricated by spark plasma sintering with various feedstock materials, thermal gradients, and controlled pressure, which result in radially distributed porosity and grain size ranging from nanometers to microns. These strategic pore and grain size distributions allow for minimal impact on fracture mechanics while simultaneously improving specific strength, impact toughness, and wear resistance. Mechanical properties are characterized at multiple length scales including macroscale compression testing, microhardness testing, and nanoindentation at both ambient and elevated temperatures. Results show significant enhancement compared to the fully dense counterparts.
