Abstract
Nickel-tin alloys containing 5-25 per cent of tin are improved by rapidly cooling from above 900 DEG C. and then annealing at 400-800 DEG C. In an example an alloy containing 15 per cent of tin is quenched from 1100 DEG C. and annealed for 1 hour at 700 DEG C. The Specification as open to inspection under Sect. 91 (3) (a) states that up to 40 per cent of one or more of the elements, aluminium, chromium, cobalt, copper, iron and manganese may be added to the nickel-tin alloys. This subject-matter does not appear in the Specification as accepted.
