20090165899 | COPPER BASE ROLLED ALLOY AND MANUFACTURING METHOD THEREFOR - A copper base rolled alloy has a copper base alloy composition containing 0.05 percent by mass or more, and 10 percent by mass or less of at least one type of element selected from Be, Mg, Al, Si, P, Ti, Cr, Mn, Fe, Co, Ni, Zr, and Sn, wherein the X-ray diffraction intensity ratio I(111)/I(200) of (hkl)plane measured with respect to a rolled surface is 2.0 or more. | 07-02-2009 |
20100009212 | METAL SHEET ROLLING METHOD AND ROLLED SHEET MANUFACTURED BY METAL SHEET ROLLING METHOD - The present invention provides a metal sheet rolling method of rolling a metal sheet with a pair of rolls, as well as a rolled sheet manufactured by the metal sheet rolling method. In the metal sheet rolling method, respective interfaces between the pair of rolls and the metal sheet have mutually different frictions. Additionally at least one of the interfaces may be lubricated by a procedure other than lubrication by coating of a liquid lubricant agent. Alternatively at least one of the interfaces may be subjected to surface treatment by a procedure other than lubrication, or otherwise the pair of rolls may be made of mutually different materials. | 01-14-2010 |

20120145438 | COPPER ALLOY FOIL, FLEXIBLE PRINTED CIRCUIT BOARD USING THE SAME, AND METHOD FOR PRODUCING COPPER ALLOY FOIL - The zirconium content of the alloy composition of a copper alloy foil of the present invention is 3.0 to 7.0 atomic percent, and the copper alloy foil includes copper matrix phases and composite phases composed of copper-zirconium compound phases and copper phases. As shown in FIG. | 06-14-2012 |
20120148441 | COPPER ALLOY WIRE AND METHOD FOR PRODUCING THE SAME - The zirconium content of the alloy composition of a copper alloy wire is 3.0 to 7.0 atomic percent; and the copper alloy wire includes copper matrix phases and composite phases composed of copper-zirconium compound phases and copper phases. The copper matrix phases and the composite phases form a matrix phase-composite phase fibrous structure and are arranged alternately parallel to an axial direction as viewed in a cross-section parallel to the axial direction and including a central axis. The copper-zirconium compound phases and the copper phases in the composite phases also form a composite phase inner fibrous structure and are arranged alternately parallel to the axial direction at a phase pitch of 50 nm or less as viewed in the above cross-section. This double fibrous structure presumably makes the copper alloy wire densely fibrous to provide a strengthening mechanism similar to the rule of mixture for fiber-reinforced composite materials. | 06-14-2012 |
20130000792 | HEAT TREATMENT METHOD AND HEAT TREATMENT APPARATUS - A heat treatment method according to the present invention includes a preliminary-state-generating step of heat-treating an alloy that undergoes multiple-step transformation with temperature by bringing the alloy in contact with a contact-type heating element for 0.01 sec or more and 3.0 sec or less, the contact-type heating element being adjusted to a particular temperature within a preliminary-state-generating temperature region determined on the basis of a first temperature related to a particular first transformation of the alloy and a second temperature, which is higher than the first temperature, related to a particular second transformation of the alloy so as to generate a preliminary state in the alloy. | 01-03-2013 |
20140079891 | METHOD FOR TREATING Cu THIN SHEET - A method for treating a Cu thin sheet is provided. The method comprises the steps of: supplying a slurry in which a diffusion bonding aid (DBA), such as Ni powder, and a reinforcing material (RM), such as a carbide base metal compound, are dispersed in a solvent to a predetermined portion on a Cu or Cu base alloy thin sheet, drying the supplied slurry, and applying a laser to induce melting, solidification, and fixation, so as to form a buildup layer. In the method, the weight ratio of DBA to RM is specified to be 80:20 to 50:50, and the median diameters D | 03-20-2014 |
