(JA) TiAl合金体の水素化脱水素化方法及びTiAl合金粉末の製造方法
Abstract: front page image
(EN) According to the present invention, a powder of a TiAl alloy is adequately produced. A hydrogenation-dehydrogenation method for a TiAl alloy according to the present invention comprises: a hydrogenation step wherein a TiAl alloy is hydrogenated in an environment where the temperature is set to a temperature at which phase transformation to the β phase starts or higher; and a dehydrogenation step wherein the hydrogenated TiAl alloy is dehydrogenated.
(FR) Selon la présente invention, une poudre d'alliage TiAl est produite de manière adéquate. Un procédé d'hydrogénation-déshydrogénation pour un alliage TiAl selon la présente invention comprend : une étape d'hydrogénation dans laquelle un alliage TiAl est hydrogéné dans un environnement où la température est réglée à une température à laquelle une transformation de phase à la phase ß commence ou plus; et une étape de déshydrogénation dans laquelle l'alliage TiAl hydrogéné est déshydrogéné.
(JA) TiAl合金の粉末を適切に製造する。TiAl合金体の水素化脱水素化方法は、TiAl合金体を、β相への相変態が開始する温度以上である設定温度の環境下で水素化処理する水素化処理ステップと、前記水素化処理を行ったTiAl合金体を、脱水素化処理する脱水素化処理ステップと、を有する。
