Title (EN) METHOD FOR PRODUCING TURBINE VANE
(FR) PROCÉDÉ DE PRODUCTION D'AUBE DE TURBINE
(JA) タービン翼の製造方法
Abstract:
(EN) This method for producing turbine vane includes a brazing step in which, in a state in which the substrate of a turbine vane having a brazing material positioned thereupon is positioned within a predetermined furnace having a heater, the heater is operated to heat the substrate to a first temperature, thereby melting the brazing material and bonding the same to the substrate; an annealing step performed after the brazing step, in which the heater is stopped, thereby lowering the furnace temperature and cooling the substrate; and a solid solution treatment step performed after the annealing step, in which the substrate is heated to a second temperature lower than the first temperature, to improve the ductility of the substrate.
(FR) L'invention concerne un procédé de production d'aube de turbine comprenant une étape de brasage dans laquelle, dans un état dans lequel le substrat d'une aube de turbine dont un matériau de brasage est positionné sur ce dernier est positionné à l'intérieur d'un four prédéfini ayant un dispositif de chauffage, le dispositif de chauffage est utilisé pour chauffer le substrat à une première température, ce qui fait fondre le matériau de brasage et le lie au substrat ; une étape de recuit réalisée après l'étape de brasage, dans laquelle le dispositif de chauffage est arrêté, ce qui abaisse la température du four et refroidit le substrat ; et une étape de traitement de solution solide réalisée après l'étape de recuit, dans laquelle le substrat est chauffé à une seconde température inférieure à la première température, pour améliorer la ductilité du substrat.
(JA) ヒータを有する所定の加熱炉内にろう材が配置されたタービン翼の母材を配置した状態でヒータを作動させて第1温度で加熱し、ろう材を溶融させて母材に接合するろう付け処理を行うことと、ろう付け処理の後、ヒータを停止させることで炉内温度を低下させて母材を冷却する徐冷を行うことと、徐冷の後、母材を第1温度よりも低い第2温度で加熱して母材の延性を高める溶体化処理を行うこととを含む。
