  • FRICTION STIR WELDING METHOD
    Publication number: 20180207746
    Abstract: A friction stir welding method of welding first and second members to each other by rotating and pressing a friction stir tool into butt surfaces of the first and second members and moving the friction stir tool while rotating the friction stir tool, includes: a butt process of abutting the first and second members on each other, and abutting a side surface of a third member on side surfaces of the first and second members; an offset process of making a rotation center of the friction stir tool coincide with a position offset from the butt surfaces, and moving the friction stir tool to reach an inside of the third member; and a welding process of making the rotation center coincide with the butt surfaces, and moving the friction stir tool to reach the inside of the third member.

  • Three-metallic-component type composite nanometallic paste, method of bonding, and electronic component
    Patent number: 8497022
    Abstract: Provided is a composite nanometal paste which, when a layer of the paste interposed between upper and lower bodies is sintered in an inert gas under no load until the layer turns to a metal layer, attains a shear bond strength between the upper and lower bodies of 10 MPa or higher. The composite nanometal paste contains, as metallic components, composite metallic nanoparticles comprising metal cores with an average particle diameter of X (nm) and an organic coating layer formed around the circumference, metallic nanofiller particles having an average particle diameter of d (nm), and metallic filler particles having an average particle diameter of D (nm), and satisfies the first relation X<d<D and the second relation X<d<100 (nm).
