Abstract
Permanent magnets are made of alloy steel containing 10-30 per cent of nickel, 4,5-30 of cobalt and 8,1-15,0 of titanium which is quenched from a temperature between 1100 DEG C. and the solidus point down to a temperature of 450-850 DEG C. and is then annealed. The alloy may first be quenched down to a temperature above the annealing temperature (400-800 DEG C.), gradually cooled to that temperature and then annealed by being maintained at this temperature for 1/2 to 6 hours before being cooled to room temperature. The alloy also may be quenched from a temperature of 1100-1300 DEG C. down to 550-750 DEG C. in a metal or salt bath, held there until it is annealed, and then cooled or may only be held in the bath long enough to acquire the temperature of the latter when it is slowly cooled to room temperature and then annealed at 650-680 DEG C. The treatment of an alloy containing 16 per cent of nickel, 28 of cobalt, 12 of titanium, 4,5 of aluminium and the rest iron, is referred to.
