Abstract : The report summarizes the findings of several investigations involving the influence of process variables on the production of shapes with specified geometry and controlled microstructure. The studies included: the extrusion consolidation of pre-alloyed metal powders (7075 Aluminum and Rene 95); a refinement of the analysis and application of the ring compression test; the use of hardness testing to evaluate the strength of hot deformed product; investigations of the effect of processing variables on extruded product and extrusion pressures; the fabrication of a heated die forging system and a preliminary investigations of lubricants; an analysis of some published flow stress data for Ti-6Al-4V; studies of grain growth in some titanium-base alloys and a comparison of grain boundary and sub-boundary strengthening in aluminum.
