Abstract

A method of producing articles and forgings that have a coefficient of thermal expansion not exceeding 2 x 10-6/ºC in the range of -150 to + 150ºC and a tensile strength load of at least 750 MN/m2 at 20ºC, characterized by forming a melt of an alloy containing, by weight, 31.8 to 38.75% nickel, 5 to 9% cobalt, not more than 0.05% carbon and 1 to 2.5% of titanium without combining, the rest being iron, apart from impurities, with the conditions that: (a)% Ni +% Co -3.7 (% Ti) = 33.5 to 35.5 (b)% Ni-3.7 (% Ti)> 0.47 (% Fe) and (c)% Co &g; 2 (% Ti) +1, cast the melt, forge the cast alloy into a shaped article, and treat by forging and maturing the forged article.
