A novel, two-step, solid-state method to produce complex geometry titanium parts was investigated by combining Cold Isostatic Pressing (CIP) with Field Assisted Sintering Technology (FAST). Hydride-dehydride powders of commercially pure and Ti-6Al-4V were CIP’ed into shaped compacts using silicone moulds, then further consolidated FAST, ZrO2 powder as a secondary pressing media. The final retai...
