Title (EN) MOLDED PRODUCT MANUFACTURING METHOD AND MOLDED PRODUCT
(FR) PROCÉDÉ DE FABRICATION D'UN PRODUIT MOULÉ ET PRODUIT MOULÉ
(JA) 成形品の製造方法、及び成形品
Abstract:
(EN) Provided is a molded product manufacturing method in which a molded product is manufactured by applying, to a metal sheet which has a bcc structure and in which the surface of the metal sheet satisfies condition (a) or (b), a molding process whereby plane strain tensile deformation and biaxial tensile deformation occur and at least a portion of the metal sheet experiences a sheet thickness reduction of 10% to 30% inclusive. (a) The area fraction of crystal grains having a crystal orientation within 15° from the {001} plane, which is parallel to the surface of the metal sheet, is 0.20 to 0.35 inclusive. (b) The area fraction of crystal grains having a crystal orientation within 15° from the {001} plane, which is parallel to the surface of the metal sheet, is 0.45 or less, and the average crystal particle size of such crystal grains is 15 μm or smaller. Also provided is a molded product that satisfies condition (a) or (b).
(FR) L'invention concerne un procédé de fabrication d'un produit moulé selon lequel un produit moulé est fabriqué par l'application, sur une feuille métallique qui présente une structure cubique centrée et dans laquelle la surface de la feuille métallique satisfait la condition (a) ou (b), d'un processus de moulage par lequel une déformation de traction de contrainte plane et une déformation de traction biaxiale se produisent et au moins une partie de la feuille métallique subit une réduction d'épaisseur de feuille de 10 % à 30 % inclus. (a) La fraction surfacique des grains cristallins présentant une orientation cristalline dans les 15° à partir du plan {1}, qui est parallèle à la surface de la feuille métallique, est comprise entre 0,20 et 0,35 inclus. (b) La fraction surfacique des grains cristallins présentant une orientation cristalline dans les 15° à partir du plan {1}, qui est parallèle à la surface de la feuille métallique, est inférieure ou égale à 0,45 et la taille moyenne des particules cristallines de ces grains cristallins est inférieure ou égale à 15 µm. L'invention concerne également un produit moulé qui satisfait la condition (a) ou (b).
(JA) bcc構造を有し、金属板の表面において下記(a)又は(b)の条件を満たす金属板に対して、平面ひずみ引張変形および二軸引張変形が生じ、かつ前記金属板の少なくとも一部が板厚減少率10%以上30%以下となる成形加工を施し、成形品を製造する成形品の製造方法。(a)前記金属板の表面に平行な{001}面から15°以内の結晶方位を持つ結晶粒の面積分率が0.20以上0.35以下である。(b)前記金属板の表面に平行な{001}面から15°以内の結晶方位を持つ結晶粒の、面積分率が0.45以下かつ、平均結晶粒径が15μm以下である。また、上記(a)又は(b)の条件を満たす成形品である。
