Abstract : The objective of the contract effort was to 'ascertain the processing sequences and methods needed to produce precision forged structural and jet engine components from metal powder preforms of titanium alloys.' This objective was attained in that an economical powder production process (Hydride-Dehydride) was identified. A technique isostatic pressing followed by high temperature vacuum sintering was identified and a procedure established to consolidate the powders into complex forging preforms a configurations at about 85 to 90% theoretical density. The forging sequence to density these preforms to 100% theoretical density was established. (Author)
