Abstract

Abstract A wear-resistant alloy of high permeability having an effective permeability of at least about 3,000 at 1 KHz, a saturation magnetic flux density of at least about 4,000 G, and a recrystallization texture of {110}<112>+{311}<112> is provided. The alloy is produced by cold working a forged or hot worked ingot of an alloy of a desired composition at a cold working ratio of at least about 50%, heating the cold worked alloy at a temperature which is below the m.p. of the alloy and not less than about 900 DEG C., and cooling the heated alloy from a temperature which is not less than an order-disorder transformation point (about 600 DEG C.) of the alloy. Alternatively, the alloy is produced by reheating the cooled alloy to a temperature which is not over than the order-disorder transformation point, and cooling the reheated alloy.
