Title (EN) HIGH-TEMPERATURE AXLE BEARING FORMED FROM NI3(SI,TI) INTERMETALLIC COMPOUND ALLOY AND METHOD FOR PRODUCING SAME
(FR) PALIER D'AXE TENANT AUX TEMPÉRATURES ÉLEVÉES FORMÉ À PARTIR D'UN ALLIAGE COMPOSITE INTERMÉTALLIQUE NI3(SI, TI) ET SON PROCÉDÉ DE FABRICATION
(JA) Ni3(Si,Ti)系金属間化合物合金で形成された高温用軸受及びその製造方法
Abstract: front page image
(EN)Disclosed is an axle bearing that has an excellent lifespan at high temperatures. The high-temperature axle bearing is characterized by being formed from a Ni3(Si,Ti) intermetallic compound alloy, which has a Vickers hardness of 210-280 at 800°C, and which has 25-500 ppm by mass of B with respect to the total mass of the composition of 100% of the atoms, including Ni as the primary component and 7.5-12.5% Si atoms, 4.5-10.5% Ti atoms, 0-3% Nb atoms, and 0-3% Cr atoms.
(FR)L'invention porte sur un palier d'axe qui a une excellente durée de vie aux températures élevées. Le palier d'axe tenant aux températures élevées est caractérisé par le fait qu'il est formé d'un alliage composite intermétallique Ni3(Si, Ti) qui a une dureté Vickers de 210-280 à 800°C, et qui a 25-500 ppm en masse de B par rapport à la masse totale de la composition de 100 % des atomes, comprenant Ni comme composant primaire et 7,5-12,5 % d'atomes de Si, 4,5-10,5 % d'atomes de Ti, 0-3 % d'atomes de Nb et 0-3 % d'atomes de Cr.
(JA) 高温で優れた寿命を備える軸受を提供する。 この発明によれば,Niを主成分とし且つSi:7.5~12.5原子%,Ti:4.5~10.5原子%,Nb:0~3原子%,Cr:0~3原子%を含む合計100原子%の組成の合計重量に対してB:25~500重量ppmを含み、800℃におけるビッカース硬さが210~280であるNi3(Si,Ti)系金属間化合物合金で形成されたことを特徴とする高温用軸受が提供される。
