Abstract
(EN)
The present invention is a conductive material comprising 10 to 70% by mass inclusive of Ag, 30 to 90% by mass inclusive of Pd, more than 5% by mass and 45% by mass or less of Ni and unavoidable impurities, wherein the ratio of the Ni content (% by mass) to the Ag content (% by mass) (i.e., (Ni (% by mass)/Ag (% by mass)), is 0.1 to 5.0 inclusive, and the metal structure is composed of an Ag-Pd alloy phase and a Pd-Ni alloy phase wherein the volume ratio of the Pd-Ni alloy phase is 18 to 80% by volume inclusive. In the present invention, the alloy is strengthened as a whole by controlling the amount of the Pd-Ni alloy phase generated as a separate phase while adding a high concentration of Ni to the Ag-Pd alloy intentionally. The alloy has satisfactory processability, and is improved in a rigidity modulus and recrystallization properties compared with the conventional alloys.

La présente invention est un matériau conducteur comprenant de 10 à 70 % en masse inclus d'Ag, de 30 à 90 % en masse inclus de Pd, plus de 5 % en masse et 45 % en masse ou moins de Ni et des impuretés inévitables, le rapport de la teneur en Ni (% en masse) vis-à-vis de la teneur en Ag (% en masse) (c'est-à-dire, (Ni (% en masse)/Ag (% en masse)), est de 0,1 à 5,0 inclus, et la structure métallique est composée d'une phase d'alliage Ag-Pd et d'une phase d'alliage Pd-Ni, le rapport volumique de la phase d'alliage Pd-Ni étant de 18 à 80 % en volume inclus. Dans la présente invention, l'alliage est renforcé dans son ensemble par la régulation de la quantité de la phase d'alliage Pd-Ni générée en tant que phase séparée tout en ajoutant intentionnellement une concentration élevée de Ni à l'alliage Ag-Pd. L'alliage présente une aptitude au traitement satisfaisante, et est amélioré en termes de module de rigidité et de propriétés de recristallisation par rapport aux alliages classiques.

本発明は、10質量%以上70質量%以下のAgと、30質量%以上90質量%以下のPdと、5質量%超45質量%以下のNiと、不可避不純物からなる導電材料であって、Ni含有量(質量%)とAg含有量(質量%)の比率(Ni(質量%)/Ag(質量%))が0.1以上5.0以下であり、金属組織において、AgPd合金相とPdNi合金相とからなり、前記PdNi合金相の体積率が18体積%以上80体積%以下である導電材料である。本発明は、AgPd合金に敢えて高濃度のNiを添加しつつ、分離相として生成するPdNi合金相の量を制御することで、合金全体の強化を図っている。この合金は、加工性も良好であり、更に、従来合金よりも剛性率と再結晶特性が改善されている。
