Title (EN) HOT STAMP MEMBER
(FR) ÉLÉMENT D'ESTAMPAGE À CHAUD
(JA) ホットスタンプ部材
Abstract:
(EN) The hot stamp member according to the present invention comprises a steel material, an Al-Fe intermetallic compound layer formed on the steel material, and an oxide film layer formed on the Al-Fe intermetallic compound layer. The oxide film layer includes: one or more group A elements selected from the group consisting of Be, Mg, Ca, Sr, Ba, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn; Al; oxygen; and impurities. The ratio of the group A element(s) excluding the oxygen in the oxide film layer is 0.01-80 at%, and the thickness t of the oxide film layer is 0.1-10.0 μm. When the group A element(s) in the oxide film layer is measured in the thickness direction from the surface of the oxide film layer by using GDS, the maximum value of the detected intensity of the group A element(s) in the range of 1/3 times the thickness t from the surface is 3.0 times or more of the average value of the detected intensity of the group A element(s) in the range from 2/3 times the thickness t to the thickness t.
(FR) Selon la présente invention, un élément d'estampage à chaud comprend un matériau d'acier, une couche de composé intermétallique Al-Fe formée sur le matériau d'acier, et une couche de type film d'oxyde formée sur la couche de composé intermétallique Al-Fe. La couche de type film d'oxyde comprend : au moins un élément du groupe A choisi dans le groupe constitué par Be, Mg, Ca, Sr, Ba, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu et Zn ; Al ; oxygène ; et des impuretés. Le rapport d'éléments du groupe A, à l'exclusion de l'oxygène dans la couche de type film d'oxyde, est de 0,01 à 80 %, et l'épaisseur t de la couche de type film d'oxyde est de 0,1 à 10,0 µm. Lorsque le (les) élément(s) du groupe A, dans la couche de type film d'oxyde, est (sont) mesuré(s), dans le sens de l'épaisseur à partir de la surface de la couche de type film d'oxyde, à l'aide de GDS, la valeur maximale de l'intensité détectée de (des) élément(s) du groupe A dans la plage de 1/3 fois l'épaisseur t à partir de la surface est de 3,0 fois ou plus la valeur moyenne de l'intensité détectée de (des) élément(s) du groupe A dans la plage de 2/3 fois l'épaisseur t par rapport à l'épaisseur t.
(JA) このホットスタンプ部材は、鋼材と、前記鋼材上に形成されたAl-Fe金属間化合物層と、前記Al-Fe金属間化合物層上に形成された酸化膜層と、を有し、前記酸化膜層が、Be、Mg、Ca、Sr、Ba、Sc、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Znからなる群から選択される1種または2種以上のA群元素と、Alと、酸素と、不純物とからなり、前記酸化膜層中の前記酸素を除く前記A群元素の比率が0.01原子%以上、80原子%以下であり、前記酸化膜層の厚みtが0.1~10.0μmであり、GDSを用いて、前記酸化膜層の表面から厚み方向に、前記酸化膜層中のA群元素を測定した場合に、前記表面から前記厚みtの1/3倍までの範囲における前記A群元素の検出強度の最大値が、前記厚みtの2/3倍からtまでの範囲における前記A群元素の検出強度の平均値の、3.0倍以上である。
