Abstract
(EN) A dissimilar metal material joint structure 1 is mainly composed of a first joining material 3, a second joining material 5, a three-dimensional structural body 7, and the like. The three-dimensional structural body 7 is joined to the top of the first joining material 3. Spaces 9b in the three-dimensional structural body 7 are filled with the second joining material 5, so that the second joining material 5 is geometrically integrated with the three-dimensional structural body 7. As described above, the three-dimensional structural body 7 is joined to the first joining material 3 at an interface 11. The second joining material 5 is charged into the spaces 9b in the three-dimensional structural body 7 and is integrated with the three-dimensional structural body 7. The first joining material 3 and the second joining material 5 are joined together via the three-dimensional structural body 7. At this time, because the second joining material 5 is charged into the spaces 9b in the three-dimensional structural body 7, the second joining material 5 and the three-dimensional structural body 7 are strongly joined and integrated together by the anchor effect. Furthermore, the bonding (tensile) strength can be increased by inducing metallurgical reaction at the interface between the first joining material and the second joining material.
(FR) Une structure d'assemblage de matériaux métalliques dissemblables (1) est principalement composée d'un premier matériau de jonction (3), d'un second matériau de jonction (5), d'un corps structurel tridimensionnel (7) et analogues. Le corps structural tridimensionnel (7) est relié à la partie supérieure du premier matériau de jonction (3). Des espaces (9b) dans le corps structurel tridimensionnel (7) sont remplis avec le second matériau de jonction (5), de telle sorte que le second matériau de jonction (5) est géométriquement intégré au corps structurel tridimensionnel (7). Comme décrit ci-dessus, le corps structural tridimensionnel (7) est relié au premier matériau de jonction (3) au niveau d'une interface (11). Le second matériau de jonction (5) est chargé dans les espaces (9b) dans le corps structurel tridimensionnel (7) et est intégré au corps structurel tridimensionnel (7). Le premier matériau de jonction (3) et le second matériau de jonction (5) sont reliés l'un à l'autre par l'intermédiaire du corps structurel tridimensionnel (7). A ce moment, du fait que le second matériau de jonction (5) est chargé dans les espaces (9b) du corps structurel tridimensionnel (7), le second matériau de jonction (5) et le corps structurel tridimensionnel (7) sont solidement assemblés et intégrés ensemble par effet d'ancrage. En outre, la résistance de liaison (en traction) peut être augmentée par induction d'une réaction métallurgique au niveau de l'interface entre le premier matériau de jonction et le second matériau de jonction.
(JA) 異種金属材料接合構造物1は、主に、第1接合材3、第2接合材5及び三次元構造体7等から構成される。第1接合材3上には、三次元構造体7が接合される。三次元構造体7の空間部9bには、第2接合材5が充填されて、三次元構造体7と幾何学的に一体化する。前述したように、三次元構造体7は、第1接合材3と界面11で接合される。また、第2接合材5は、三次元構造体7の空間部9bに充填されて一体化する。第1接合材3と第2接合材5とは三次元構造体7を介して接合される。この際、第2接合材5は、三次元構造体7の空間部9bに充填されているため、アンカー効果によって強固に接合されて一体化される。また、第1の接合材と第2の接合材との界面の冶金的反応を起こすことにより、接合(引張)強度を向上させることができる。
