Abstract:
(EN) Provided is a clock component including a titanium alloy, wherein the titanium alloy contains, in percent by mass, 1.0-3.5% of Al, 0.1-0.4% of Fe, 0.00-0.15% of O, 0.00-0.10% of C, 0.00-0.20% of Sn, and 0.00-0.15% of Si, the balance being Ti and unavoidable impurities. The average grain size of α-phase crystal grains is 15.0 μm or less, the average aspect ratio of the α-phase crystal grains is 1.0-3.0 (inclusive), and the variation coefficient of the number density of β-phase crystal grains dispersed in the α phase is 0.30 or less.
(FR) L'invention concerne un élément d'horloge comprenant un alliage de titane, l'alliage de titane contenant, en pourcentage en masse, de 1,0 à 3,5 % d'Al, de 0,1 à 0,4 % de Fe, de 0,00 à 0,15 % d'O, de 0,00 à 0,10 % de C, de 0,00 à 0,20 % de Sn, et de 0,00 à 0,15 % de Si, le complément étant constitué de Ti et d'impuretés inévitables. La granulométrie moyenne des grains cristallins en phase α est inférieure ou égale à 15,0 μm, le rapport de forme moyen des grains cristallins en phase α va de 1,0 à 3,0 (inclus), et le coefficient de variation de la densité du nombre de grains cristallins en phase β dispersés dans la phase α est inférieur ou égal à 0,30.
(JA) チタン合金を含む時計部品であって、前記チタン合金は、質量%で、Al:1.0~3.5%、Fe:0.1~0.4%、O:0.00~0.15%、C:0.00~0.10%、Sn:0.00~0.20%、Si:0.00~0.15%、及び残部:Ti及び不純物からなり、α相の結晶粒の平均粒径が15.0μm以下であり、α相の結晶粒の平均アスペクト比が1.0以上3.0以下であり、α相中に分散したβ相の結晶粒の数密度の変動係数が0.30以下である。
