    摘要： [Object] To provide a joining method for dissimilar metals which are magnesium alloy and steel and difficult to be metallurgically directly joined to each other while oxide film is present at a joining surface.
    [Solving means] In order to join magnesium alloy material 1 and steel plate 2 to each other, a galvanized steel plate to which Zn-Al-Mg alloy plating (a third material) is applied is used as the steel plate 2. When joining is made, ternary eutectic melting of Al-Mg-Zn is caused, so that it is discharged together with oxide film 1f and impurities from the joining interface while Al-Mg intermetallic compound such as Al 3 Mg 2 and Fe-Al intermetallic compound such as FeAl 3 are formed, thereby joining the newly generated surfaces of the magnesium alloy material 1 and the steel plate 2 to each other through a compound layer 3 containing these intermetallic compounds.

    摘要： The present invention provides a method for joining metal materials which can directly join the metal materials at least either one of which has an oxide film on the surface to each other, and can be performed in the air, at low temperature, under low pressure and at low cost. To join a first member 1 with at least a joining face made of Metal A to a second member 2 with at least a joining face made of Metal B, an insert 3 is interposed between the joining faces, and the members are heated while applying an opposing pressure, so that the insert 3 causes an eutectic reaction with both Metal A and Metal B, and the eutectic melt is discharged from the joining face along with oxide films 1 f and 2f of the Metal A and Metal B. The first and second members 1 and 2 are thus joined to each other.

    摘要： An inexpensive bonding method is provided with which it is possible to bond materials constituted of an aluminum-based metal to each other at a low temperature and a low pressure in the air while inhibiting deformation and without requiring the use of a flux and to minimize the influence on the base materials and on the periphery. Also provided are various bonded parts obtained by applying the bonding method. An insert material (2) comprising Zn as an element that undergoes a eutectic reaction with Al is interposed between two materials (1, 1) constituted of an aluminum-based metal. The two materials (1, 1) are heated, while being pressed against each other, to a temperature at which the eutectic reaction takes place, thereby generating, at the bonding interface between the two materials (1, 1), a melt due to the eutectic reaction with some of the Al contained in the base materials and discharging the Al oxide films (1a) from the bonding interface together with the melt. Thus, the two materials are bonded.
