Abstract
A method for heat treating a powder part preform including a titanium-based alloy, wherein the method includes the heat treatment of the preform in a furnace at a predetermined temperature, wherein the preform is on a holder during the heat treatment, wherein the holder includes a zirconium-based alloy having a zirconium content greater than or equal to 95% by weight, wherein the holder material has a melting temperature higher than the predefined temperature of the heat treatment, and wherein an anti-diffusion barrier is arranged between the preform and the holder in order to prevent welding of the preform to the holder.
