    摘要： There is provided an austenitic stainless steel which is corrosion-resistant in an environment of neutron irradiation, and can suppress stress corrosion cracking and embrittlement. At least one kind of additive selected from Ti more than 0.2 % by weight up to 0.6 %, Zr more than 0.2 % up to 1.14%, Hf more than 0.2% up to 2.24 %, V more than 0.2 % up to 0.64 %, Nb more than 0.5 % up to 1.17 % and Ta more than 0.5 % up to 2.27 % is added to austenitic stainless steel containing Cr, Ni and so on, and said at least one additive exists in a solid-solution state. Further, the steel has a wholly austenitic structure substantially free of carbide. In order to maintain the irradiation-induced segregation prevention effected by the addition element, the C content is limited to 0.01 to 0.008 %, and the N content is limited to 0.001 to 0.1 %. The irradiation-induced segregation of the constituent elements, such as Cr and Ni, occurring in a grain boundary under irradiation, and the deterioration of the corrosion resistance of the material, as well as the embrittlement, can be prevented.

    摘要： It is an object of the present invention to provide a friction stir welding method and apparatus capable of maintaining a rotating tool and workpieces at a substantially constant geometrical relation for arbitrary curved surfaces having a three-dimensional shape, as well as a welded structure obtained thereby.
    The present invention resides in a friction stir welding method comprising joining workpieces while setting rotational angles of two rotational axes of a rotating tool which the two rotational axes are rotatable in intersecting directions or perpendicularly intersecting directions independently of rotation of the rotating tool, detecting a normal line direction with respect to joint surfaces of the workpieces and a tangential direction of a joint line, and joining the workpieces in three-dimensional directions while setting, on the basis of the detected normal line direction and tangential direction, an angle relative to a normal line direction, as well as a tangential direction, at a tip end of the rotating tool, and also resides in a friction stir welding apparatus using the said method.
