Includes bibliographical references (leaves 110-111). === The focus of this study was the use of powder metallurgy to produce low cost titanium with comparative mechanical properties to wrought titanium. The objectives of this investigation was to produce sintered titanium compacts that represented metal made by the Direct Powder Rolling method. The critical strain (ɛC) required to induce recrystallization following deformation was determined by hot compressing wrought titanium samples. Finally sintered titanium samples were hot compressed at ɛC and the changes to the microstructure, porosity and mechanical properties was assessed.
