  • Patent number: 8840735
    Abstract: Fatigue damage resistant metal or metal alloy wires have a submicron-scale or nanograin microstructure that demonstrates improved fatigue damage resistance properties, and methods for manufacturing such wires. The present method may be used to form a wire having a nanograin microstructure characterized by a mean grain size that is 500 nm or less, in which the wire demonstrates improved fatigue damage resistance. Wire manufactured in accordance with the present process may show improvement in one or more other material properties, such as ultimate strength, unloading plateau strength, permanent set, ductility, and recoverable strain, for example. Wire manufactured in accordance with the present process is suitable for use in a medical device, or other high end application.

    Abstract: An electrical steel sheet has a component composition including, by mass %, C: 0.007% or less, Si: 4% to 10%, and Mn: 0.005% to 1.0%, the balance being Fe and incidental impurities, as well as a sheet thickness within a range of 0.01 mm or more to 0.10 mm or less, and a profile roughness. Pa of 1.0 ?m or less. The electrical steel sheet exhibits excellent iron loss properties whereby the magnetic property is free from deterioration, and degradation of the stacking factor can be avoided, even when the steel sheet with a thickness of 0.10 mm or less has been subjected to siliconizing treatment to increase the Si content in the steel.

  • Publication number: 20140220373
    Abstract: A composite dual blackened copper foil includes a copper foil and two blackened layers. The copper foil has a shiny side and a matte side. The blackened layers are formed on the shiny and matte sides respectively. The blackened layers are formed alloy by electroplating in a plating bath consisting essentially of copper, cobalt, nickel, manganese, magnesium and sodium ions. A rough layer is selectively formed between the blackened layer and the shiny side as well as the matte side. Both side of the copper foil is spotless, powder free, and good in etching quality. The copper foil is effective at blocking electromagnetic wave, near infrared, undesired light and the like. The copper foil exhibits strong light absorption and is applicable to direct gas laser drilling. A method of manufacturing the composite dual blackened copper foil is also provided.
