Abstract[English]
A method (100) of obtaining a full-density sintered titanium component can include providing (110) a titanium component having a starting density of 92% or less. The titanium component can be heated to and held at a sintering temperature (120) under a sintering atmosphere containing hydrogen with a pressure during sintering less than 0.2 MPa. This can sinter (130) the titanium component to greater than 92% theoretical density forming a sintered component. The sintered component can be held (140) at a densification temperature while applying a gaseous pressure of 0.2 MPa to 100 MPa with a densification atmosphere, to hot isostatically press (HIP) the sintered component to full density having greater than 99.5% relative density to form the full-density sintered titanium component.[French]
Un procédé (100) selon l'invention d'obtention d'un composant de titane fritté à pleine densité peut comprendre la fourniture (110) d'un composant de titane ayant une densité de départ de 92% ou moins. Le composant de titane peut être chauffé et maintenu à une température de frittage (120) sous une atmosphère de frittage contenant de l'hydrogène avec une pression pendant le frittage inférieure à 0,2 MPa. Ceci peut fritter (130) le composant de titane à une densité théorique supérieure à 92%, formant un composant fritté. Le composant fritté peut être maintenu (140) à une température de densification tout en appliquant une pression gazeuse de 0,2 MPa à 100 MPa avec une atmosphère de densification, pour presser de manière isostatique à chaud (HIP) le composant fritté jusqu'à pleine densité ayant une densité relative supérieure à 99,5% pour former le composant de titane fritté à pleine densité.
