Publication number: 20100297469Abstract: This invention provides a configuration of a joint that allows a satisfactory welded joint to be formed with reduced deformation of the joint region when two-face structures (panels) are friction-welded end to end. The panels 31, 32 each have two substantially parallel plates 33, 34 and a third member 35 connecting the two plates 33, 34. The end portions of the plates 33, 34 of one panel 32 are friction-welded to the end portions of the plates 33, 34 of the other panel 32. At least one of the panels has a plate 36 at its end for connecting the plates 33 and 34 and has a rigidity to support a pressing force produced during the friction welding.Type: ApplicationFiled: July 28, 2010Publication date: November 25, 2010Inventors: Kinya Aota, Tsuyoshi Takenaka, Yasuo Ishimaru

Publication number: 20100047110Abstract: A Ni-base superalloy of the present invention essentially includes, by weight %, Co: 9 to 11%, Cr: 9 to 12%, Mo: up to 1%, W: 6 to 9%, Al: 4 to 5%, Ti: 4 to 5%, Nb: up to 1%, Ta: up to 3%, Hf: 0.5 to 2.5%, Re: up to 3%, C: 0.05 to 0.15%, B: 0.005 to 0.015%, Zr: up to 0.05%, and the balance of Ni and inevitable impurities. This alloy, as a component material of an industrial gas turbine, has an excellent resistance to corrosion at high temperatures to deal with low-quality fuel and a resistance to oxidation at high temperatures and high-temperature strength to deal with improvement in thermal efficiency due to high-temperature demands and can ensure a high yield at a casting process.Type: ApplicationFiled: September 8, 2009Publication date: February 25, 2010Applicants: Kawasaki Jukogyo Kabushiki Kaisha, Independent Administrative Institution National Institute for Materials ScienceInventors: Masahiro Sato, Tsuyoshi Takenaka, Seiya Nitta, Toshiharu Kobayashi, Yutaka Koizumi, Hiroshi Harada
