摘要： PROBLEM TO BE SOLVED: To provide a joined body which is small in ΔT(=Tx-Tg) (Tx: crystallization temperature, Tg: glass point) and in which a joined surface is not crystallized in an amorphous metal or metal glass. SOLUTION: There is provided the amorphous metal joined body obtained by joining the amorphous metal having an irregular crystal structure by a thermal method or a method using plastic deformation. Particularly, the joined body has a nanocrystal precipitated in a joint portion. Also, the metal glass having an extensive supercooling liquid region and a distinct glass transition point is joined by the thermal method or the method using the plastic deformation.

摘要： PROBLEM TO BE SOLVED: To provide a joining method for aluminum base material by which the aluminum base materials are joined with high strength at low temperature without using a flux for removing an oxidized coating film, and the cost is reduced by eliminating the need of a flux cleaning stage after joining, and to provide a joining structure by the joining method.
SOLUTION: In the state that an intermediate material 3 composed of metallic glass containing an element, for example La, whose standard generated free energy of oxidation is smaller than aluminum and having the melting point lower than that of the materials to be joined is interposed between materials 1, 2 to be joined consisting of aluminum or an aluminum alloy, the intermediate material 3 is heated to the temperature to the melting point or above of the intermediate material 3 and the melting point or below of the materials 1, 2 to be joined, so that the materials 1, 2 to be joined are joined without using the flux.
