Abstract

Alloys resistant to mechanical stress and chemical action comprise iron, cobalt or an iron cobalt alloy and 2 to about 10 per cent of thorium. One or more elements which improve the properties of the alloys without modifying the action of the thorium may be added in a total proportion of about 20 per cent to the alloys. Examples of such additions are chromium up to 20 per cent, tungsten up to 20 manganese up to 20, titanium 0,1-12, molybdenum up to 15, aluminium up to 12 or silicon up to 15. The alloys are prepared by melting in a high vacuum to prevent oxidation and the formation of other impurities. The Specification as open to inspection under Sect. 91, refers to alloys containing nickel, copper or nickel-copper or nickel-iron and thorium, and also the addition of chromium to iron-nickel-thorium alloy, the thorium content being up to 50 per cent. This subject-matter does not appear in the Specification as accepted.
