Titanium (Ti) alloys are attractive candidates for aerospace structural applications due to their high specific strength and retention of mechanical properties up to temperatures of ~500 degree C. However, their susceptibility to contamination in the molten state necessitates use of solid state processing methods, such as Linear/Translational Friction Welding (LFW/TFW). In this work, micro-mesoscale characterization of similar and dissimilar alpha+beta-Ti welded joints is presented. Evidence of static and dynamic recrystallization has been observed, which are attributed to process variables such as temperature, strain, and strain-rate. These parameters are systematically studied to establish structure-property relationships using Scanning Electron Microscopy (SEM) combined with Electron Back Scattered Diffraction (EBSD) techniques.
