Abstract
A method for heat treating a powder part preform including a titanium alloy, includes heat treating the preform in a furnace at a predefined temperature, wherein the preform is on a holder during the heat treatment. The holder includes a titanium alloy having a mass titanium content no lower than 45%, or a zirconium alloy having a mass zirconium content no lower than 95%, wherein the material making up the holder has a melting temperature higher than the predefined heat treatment temperature, and an antidiffusion barrier is arranged between the preform and the holder to prevent the preform from becoming welded to the holder.
