Abstract

An alloy having a zero or very low coefficient of linear thermal expansion consists of about 46-70 per cent of iron, 23-53 per cent of nickel, and less than 34 per cent of cobalt, with or without less than 2 per cent of one or more of the elements manganese, silicon, aluminium, titanium, vanadium, magnesium, or carbon, or less than 4,5 per cent of chromium. The alloy may be improved by being quenched from about 1000 DEG C. or worked, or both, after which it may be treated to about 100 DEG C., cooled and aged at atmospheric temperature for several months.
