    Abstract: A composite soft magnetic material having low magnetostriction and high magnetic flux density contains: pure iron-based composite soft magnetic powder particles that are subjected to an insulating treatment by a Mg-containing insulating film or a phosphate film; and Fe—Si alloy powder particles including 11%-16% by mass of Si. A ratio of an amount of the Fe—Si alloy powder particles to a total amount is in a range of 10%-60% by mass. A method for producing the composite soft magnetic material comprises the steps of: mixing a pure iron-based composite soft magnetic powder, and the Fe—Si alloy powder in such a manner that a ratio of the Fe—Si alloy powder to a total amount is in a range of 10%-60%; subjecting a resultant mixture to compression molding; and subjecting a resultant molded body to a baking treatment in a non-oxidizing atmosphere.

  • Publication number: 20130098203
    Abstract: A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. The deformation working is typically performed at a yield strength that is adjusted by way of selecting a working temperature at which the yield strength is approximately less than the omniaxial crush strength of the included ceramic microballoons. This deformation causes at least work hardening and grain refinement in the matrix metal.

  • Patent number: 8404356
    Abstract: A contact material which provides improved wear resistance as well as reduced adhesion utilizing the features of an intermetallic compound having an ordered phase, with the intention of (i) improving the seizure resistance and/or wear resistance of an implement bearing which slides under low-speed, high-surface-pressure conditions and is susceptible to lubricant starvation; (ii) preventing abnormal noises; and (iii) achieving prolonged greasing intervals. The contact material contains 10% by volume or more a metallic alloy phase having such a composition range that causes an order-disorder transition. The metallic alloy phase is a Fe base alloy phase containing one or more elements selected from the group consisting of Al, Si, Co and Ni.
