  • Material including beryllium intermetallic compound and having excellent high-temperature property applied to nuclear fusion reactor
    Patent number: 7560069
    Abstract: A material for a nuclear fusion reactor of the present invention contains intermetallic compounds of beryllium with Ti, V, Zr, Nb, Ta, Mo, W or Y. The beryllium intermetallic compounds are mixed with another metal or intermetallic compound. The material is preferably applied to blankets and facing members which are exposed to neutrons and heat generated by plasma of the nuclear fusion reactor.
    Type: Grant
    Filed: September 30, 2004
    Date of Patent: July 14, 2009
    Assignee: NGK Insulators, Ltd.
    Inventors: Hiroshi Kawamura, Munenori Uchida, Minoru Uda, Yoshio Ito

  • Method for vertically and continuously casting beryllium copper alloys
    Patent number: 5090472
    Abstract: A casting nozzle is first arranged in a melt of the beryllium copper alloy in a mold. This casting nozzle has a flow rate-regulating mechanism which is arranged in the melt in the mold and capable of regulating the flow rate of the melt to be poured into the mold. The nozzle is opened in the melt inside the mold. A melt is poured into the mold through the nozzle, and continuously cast in a casting temperature range from a liquidus temperature of the beryllium copper alloy to a temperature higher than the liquidus temperature by 50.degree. C. Thereby, the beryllium copper alloy having a crystalline structure consisting essentially of isometric crystals can be obtained.
