Abstract:
(EN) Provided is a forged aluminum alloy material which contains an excess of Si, which exhibits increased strength due to containing therein a large quantity of a strength-increasing element such as Cu or Mn, and by which high strength and high toughness can be stably obtained even if the forged aluminum alloy material is reduced in thickness, and also provided is a method for producing the same. A forged aluminum alloy material constituted from an aluminum alloy which contains prescribed quantities of Mg, Si, Cu, Fe, Ti and B and further contains prescribed quantities of one or more elements selected from among Mn, Cr and Zr, with the remainder comprising Al and unavoidable impurities, wherein the electrical conductivity at 20°C, as measured on the surface of the forged aluminum alloy material, is greater than 42.5% IACS but not more than 46.0% IACS, and the forged aluminum alloy material has a 0.2% proof stress of 360 MPa or higher and a Charpy impact value of 6 J/cm2 or higher.
(FR) Matériau d'alliage d'aluminium forgé contenant un excès de Si, qui présente une résistance accrue parce qu'il contient une grande quantité d'un élément augmentant la résistance, tel que du Cu ou Mn, et par lequel une résistance et une dureté élevées peuvent être obtenues de manière stable même si le matériau d'alliage d'aluminium forgé est réduit en épaisseur. L'invention concerne également un procédé de production dudit matériau. Un matériau d'alliage d'aluminium forgé constitué d'un alliage d'aluminium qui contient des quantités prescrites de Mg, Si, Cu, Fe, Ti et B et contient en outre une quantité déterminée d'un ou de plusieurs éléments choisis parmi Mn, Cr et Zr, avec le reste comprenant de l'Al et des impuretés inévitables. Sa conductivité électrique à 20 °C, telle que mesurée sur la surface du matériau d'alliage d'aluminium forgé, est supérieure à 42,5 % IACS mais n'excède pas 46,0 % IACS et le matériau d'alliage d'aluminium forgé a une limite d'élasticité à 0,2% de 360 MPa ou plus et une valeur de résilience Charpy à 6 J/cm2 ou plus.
(JA)  Siを過剰に含み、CuやMnなどの高強度化元素の含有量を多くして高強度化させ、かつ薄肉化されたアルミニウム合金鍛造材であっても、高強度と、高靭性が安定して得られるアルミニウム合金鍛造材およびその製造方法を提供する。Mg、Si、Cu、Fe、TiおよびBを所定量含み、更に、Mn、CrおよびZrの一種または二種以上を所定量含み、残部がAlおよび不可避的不純物からなるアルミニウム合金から構成されるアルミニウム合金鍛造材であって、アルミニウム合金鍛造材の表面で測定した20℃での導電率が42.5IACS%を超え46.0IACS%以下であり、アルミニウム合金鍛造材の0.2%耐力が360MPa以上であり、かつ、シャルピー衝撃値が6J/cm以上であることを特徴とする。
