title = "Low cost titanium near-net-shape manufacturing using armstrong process{\textregistered} CP-Ti and Ti-6Al-4V powders",
abstract = "Near-net-shape manufacturing using powder metallurgy (PM) technology and consolidation processes can significantly reduce material waste and cost during component fabrication. This study summarizes our recent efforts to evaluate near-net-shape consolidation processes utilizing commercially pure titanium (CP-Ti) and Ti-6Al-4V alloy powders made by the Armstrong Process{\textregistered} technology. Milling of the powders was systematically investigated and the impact on the particle size distribution, tap density, and the chemistry were evaluated. Press-and-sinter processing of the milled powders was also evaluated in terms of theoretical density as a function of pressure. The response from Armstrong Process{\textregistered} powder in press-and-sinter processing was compared with that obtained from conventional hydride-dehydride (HDH) powders. Near-net-shape components which were fabricated by pressing and sintering, cold isostatic pressing (CIP), hot isostatic pressing (HIP), and pneumatic isostatic forging (PIF), were shown to achieve full consolidation with more than 99.6% of the theoretical density after the final processing step. Properties of the PM materials after the consolidation process were characterized and compared to those of conventional wrought materials.",
