Total Hip Arthroplasty, THA, is a commonly available surgical procedure which is capable of providing a once arthritis stricken patient with a new range of motion they could not have benefited from before the procedure. In the past decades since the introduction of the first Total Artificial Hip, TAH, the design of the hip has progressed from glass, wood and ivory to more sophisticated materials such as titanium and cobalt-chrome alloys which are commonly used today. However, there is still room for improvement in the areas of mechanical properties, fixation and biocompatibility to name a few. This project involves the development of a novel, mechanically alloyed Titanium Aluminide for the purpose of human implant applications; the aims being improved properties including a lower elastic modulus and higher damping capacity for optimal performance, function and longevity. In this work the mechanically alloyed powder was characterized as a function of milling times and annealing temperatures using a Transmission Electron Microscope, Scanning Electron Microscope, and X-Ray Diffractometer. The data will be utilized in future work to optimize values of milling parameters to achieve amorphization or produce microcrystallites and fine crystal structures.
