Abstract:
(EN) A machine part (10) according to one embodiment of the present invention is formed from a titanium alloy. The titanium alloy contains a primary α phase and a secondary α phase. The area ratio of the primary α phase in the titanium alloy is 1% or more but less than 10%. The titanium alloy is a Ti-6Al-4V alloy.
(FR) Selon un mode de réalisation, la présente invention concerne une pièce de machine (10) à base d'un alliage de titane qui contient une phase α primaire et une phase α secondaire. La proportion en surface de la phase α primaire dans l'alliage de titane est de 1 % ou plus mais inférieure à 10 %. L'alliage de titane est un alliage Ti-6Al-4V.
(JA) 一実施形態に係る機械部品(10)は、チタン合金製である。チタン合金は、プライマリα相と、セカンダリα相とを含有する。チタン合金中におけるプライマリα相の面積率は、1パーセント以上10パーセント未満である。チタン合金は、Ti-6Al-4V合金である。
