Patent number: 4710243Abstract: A wear-resistant alloy of high permeability having an effective permeabil 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.degree. C., and cooling the heated alloy from a temperature which is not less than an order-disorder transformation point (about 600.degree. 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.Type: GrantFiled: July 29, 1985Date of Patent: December 1, 1987Assignee: The Foundation: The Research Institute of Electric and Magnetic AlloysInventors: Hakaru Masumoto, Yuetsu Murakami

Patent number: 4485153Abstract: Conductive thick film pigment-coated surfaces which possess desirable conductivity and solderability characteristics are formed from an alloy comprising a mixture of a nonnoble conductive metal, a noble metal and at least one oxidizable material. The oxidizable material is present in the alloy in an amount in the range of from about 5% to about 25% by weight, the nonnoble metal in an amount in the range of from about 94% to about 60% by weight and the noble metal in an amount in the range of from about 1% to about 15% by weight of the alloy. The desired product is prepared by admixing a nonnoble metal, an oxidizable material and a noble metal, arc-melting the mixture to form an alloy, grinding the arc-melted alloy to a powdered form, admixing the powder with the carrier binder, depositing said admixture on an inert surface, firing the admixture and surface in an oxygen-containing atmosphere at a temperature in the range of from about 500.degree. to about 950.degree.
