Abstract (en)

[origin: WO0107673A1] The invention relates to iron-nickel alloys with creep resistance and low thermal expansion, which contain ( % by mass) no more than about 0.2 % C, no more than 0.3 % Mn, no more than 0,3 % Si, from 0.05 to 3.0 % Al, 0.1 to 3.0 % Ti, no more than 1.0 % Nb, from 39.0 to 45.0 % Ni, wherein the rest is composed of iron and impurities that can be generated during the fabrication process. The inventive alloys have a thermal expansion coefficient <6.0 x 10<-6>/K in a temperature range between 20 and 100 DEG C.
