Title (EN) FeNi ORDERED ALLOY AND METHOD FOR MANUFACTURING FeNi ORDERED ALLOY
(FR) ALLIAGE ORDONNÉ DE FER/NICKEL ET PROCÉDÉ DE FABRICATION D'UN ALLIAGE ORDONNÉ DE FER/NICKEL
(JA) FeNi規則合金およびFeNi規則合金の製造方法
Abstract:
(EN) Provided is a method for manufacturing FeNi ordered alloy with an L10 ordered structure. After nitriding a powder sample (100) of a FeNi disordered alloy set in a tubular furnace (10) with NH3 gas, denitrification in which nitrogen is removed from the nitrided FeNi disordered alloy is performed using H2 gas. As a result, a L10 FeNi ordered alloy with a degree of order S of at least 0.5 is obtained.
(FR) Cette invention concerne un procédé de fabrication d'un alliage ordonné de FeNi avec une structure ordonnée L10. Après nitruration un échantillon de poudre (100) d'un alliage désordonné de FeNi disposé dans un four tubulaire (10) avec du gaz de NH3, une dénitrification au cours de laquelle l'azote est éliminé de l'alliage désordonné de FeNi nitruré est effectuée au moyen d'un gaz H2. En conséquence, un alliage ordonné de FeNi L10 présenté un degré d'ordre S supérieur ou égal à 0,5 est obtenu.
(JA) L10型の規則構造を有するFeNi規則合金の製造方法を提供する。管状炉(10)に設置されたFeNi不規則合金の粉末試料(100)をNH3ガスで窒化する窒化処理を行った後、H2ガスによって、窒化処理されたFeNi不規則合金から窒素を除去する脱窒素処理を行う。これにより、規則度Sが0.5以上であるL10型のFeNi規則合金を得る。
