Abstract | Disclosed is a creep-resistant low-expansion iron-nickel alloy that is provided with increased mechanical resistance and contains 40 to 43 wt. % of Ni, a maximum of 0.1 wt. % of C, 2.0 to 3.5 wt. % of Ti, 0.1 to 1.5 wt. % of Al, 0.1 to 1.0 wt. % of Nb, 0.005 to 0.8 wt. % of Mn, 0.005 to 0.6 wt. % of Si, a maximum of 0.5 wt. % of Co, the remainder being composed of Fe and production-related impurities. Said alloy has a mean coefficient of thermal expansion < 5 x 10 -6/K in the temperature range of 20 to 200°C.
L'invention concerne un alliage fer-nickel résistant au fluage, à faible dilatation, présentant une résistance mécanique élevée et comportant les éléments suivants exprimés en % de la masse: Ni 40 à 43 %, C max. 0,1 %, Ti 2,0 à 3,5 % AI 0,1 à 1 ,5 %, Nb 0,1 à 1 ,0 %, Mn 0,005 à 0,8 %, Si 0,005 à 0,6 %, Co max. 0,5 %, le restant étant Fe et des impuretés dues à la production. Cet alliage présente, dans la plage de température allant de 20 à 200°C, un coefficient moyen de dilatation thermique < 5 x 10-6/K. |
