Abstract:
(EN) The present invention provides a copper alloy sheet having excellent press workability, a copper alloy sheet manufacturing method, and a connector that uses a copper alloy sheet. In a copper alloy sheet 1, a cross-section 10, which includes a rolling direction and a thickness direction, comprises a quadrilateral first region 11 that is partitioned off so as to have dimensions of 100 μm in the rolling direction and the sheet thickness in the thickness direction, and that is subdivided at 10 μm intervals in the rolling direction and in the thickness direction so as to be segmented into a plurality of square second regions 12, which are 10 μm to a side. When electronic backscatter diffraction (EBSD) is used to measure the average KAM value in inner second regions 14, which define the plurality of second regions 12 constituting the first region 11 other than the outer second regions 13 forming the four sides of the first region 11, the difference (Δθ) between the maximum and minimum average KAM values is 25° or less.
(FR) La présente invention concerne une feuille d'alliage de cuivre présentant une excellente aptitude au façonnage à la presse, un procédé de fabrication de feuille d'alliage de cuivre, et un connecteur faisant internvenir une feuille d'alliage de cuivre. Dans une feuille d'alliage de cuivre (1), une section transversale (10), qui comprend une direction de laminage et une direction d'épaisseur, comprend une première région quadrilatérale (11) qui est séparée de façon à avoir des dimensions de 100 µm dans la direction de laminage et l'épaisseur de feuille dans la direction de l'épaisseur, et qui est subdivisée à des intervalles de 10 µm dans la direction de laminage et dans la direction de l'épaisseur de façon à être segmentée en une pluralité de secondes régions carrées (12), qui ont 10 µm de côté. Lorsqu'une diffraction des électrons rétrodiffusés (EBSD) est utilisée pour mesurer la valeur KAM moyenne dans les secondes régions internes (14), qui définissent la pluralité de secondes régions (12) constituant la première région (11) autres que les secondes régions externes (13) formant les quatre côtés de la première région (11), la différence (Δθ) entre les valeurs de KAM moyenne maximale et minimale est de 25° ou moins.
(JA) プレス加工性に優れた銅合金板材及び銅合金板材の製造方法並びに銅合金材を用いたコネクタを提供すること。 圧延平行方向と板厚方向を含む断面10において、100μmの圧延平行方向寸法と、板厚寸法とで区画される四角形の第1領域11を、圧延平行方向と板厚方向に10μm間隔でさらに分割して、10μm四方となる複数の正方形の第2領域12に細分化し、第1領域11を構成する複数の第2領域12のうち、第1領域11の4辺を形成する外側第2領域13を除いた内側第2領域14のそれぞれで、電子後方散乱回折法(EBSD)によってKAMの平均値を測定したとき、測定したKAMの平均値の最大値と最小値の差(Δθ)が25°以下である銅合金板材1。
