Ti-6Al-4V and CP Ti powders have been consolidated into sheet, plate and bar shapes using the near net shape powder metallurgical processes of cold roll compaction and CIP. Mechanical properties and microstructures developed in roll compacted sheet after processing to full density through cold rolling and sintering steps are discussed. Shapes formed in CIP have been taken to full density with a single PIF (pneumatic isostatic forging) step. Microstructures obtained following PIF and after subsequent heat treatment are presented.
