Definitions

  • the thermally affected zone around the weld joint is in the annealed state (state O), with less mechanical characteristics, which does not allow to exploit fully, in welded constructions, the mechanical characteristics. of the material.
  • the certification and control bodies generally recommend that only the mechanical characteristics in state O be taken into account when sizing a structure.
  • German patent DE 2443443 (Siemens AG) claims a weldable aluminum alloy machine component containing, inter alia, 3.5 to 4.9% Mg and 0.5 to 1.5% Mn. No information is given the mechanical characteristics or the corrosion resistance of this product.
  • the European patent EP 0015799 (aines et Chantiers de Bretagne) discloses a weldable alloy containing among others 3.5 to 4.5% magnesium and 0.2 to 0.7% manganese for the manufacture of tubes for cryogenic application. This application does not pose the problem of thermal sensitization to corrosion, and the document does not mention the mechanical characteristics or other properties of use of the product.
  • the US patent US 3502448 (Aluminum Company of America) discloses an alloy containing, inter alia, 4 to 5.5% magnesium, 0.2 to 0.7% manganese, which conducts, by cold rolling, to thin sheets and thin strips to the manufacture of beverage can lids, provided that the relationship between the contents of Mg and Mn is consistent with a certain algebraic relationship.
  • This patent does not concern the field of welded mechanical engineering either.
  • the problem to which the present invention attempts to respond is therefore to provide rolled, drawn or drawn AlMgMn alloy products having, after welding, improved corrosion resistance and better resistance to the sensitizing effect of exposure to temperature. , while retaining good mechanical properties after welding, good resistance to fatigue and can be developed at the lowest cost.
  • the subject of the invention is thus an AlMgMn alloy product for welded mechanical construction of composition (% by weight): 5.0 ⁇ Mg ⁇ 6.5 0.2 ⁇ Mn ⁇ 1.0 Fe ⁇ 0.8 0.05 ⁇ Si ⁇ 0.6 0.2 ⁇ Zn ⁇ 1.3 optionally Cr at a content ⁇ 0.15 and / or one or more of the elements Cu, Ti, Ag, Zr, V, at a content ⁇ 0.3 each, the unavoidable impurities ⁇ 0.05 each and ⁇ 0.15 at total, remains aluminum, wherein the number of Mg 2 Si particles of size between 0.5 and 5 ⁇ m is between 150 and 2000 per mm 2 , and preferably between 300 and 1500 per mm 2 .
  • the eutectic phases Mg 2 Si the eutectic phases AlFeMnSi, the eutectic phases Al 6 (Mn, Fe) and AlFeCr, and the manganese dispersoids, of sub-micron size, which are found in the grain.
  • the number of "large" particles should represent only a small part of the total particles (size> 0.5 ⁇ m), typically less than 25%, and preferably , less than 20%.
  • the surface fraction of Mg 2 Si particles also measured by image analysis from optical microscopy, must be less than 1%, and preferably 0.8%.
  • Manganese improves the tensile strength and decreases the tendency of the metal to recrystallize, which is known to those skilled in the art. Below 0.2%, the present invention is of no industrial interest because the resistance to the pull is too weak. Above 1%, elongation at break, tenacity and fatigue resistance become too low for the intended applications.
  • the iron content does not have much influence in the context of the present invention; it should be less than 0.8% to avoid the formation of primary phases during casting, while for high manganese contents, it is preferable that it does not exceed 0.4%.
  • Examples 1 and 2 and Example 3 (resulting in a microstructure outside the invention) correspond to composition 1.
  • Examples 7 and 8, and Example 9 (resulting in a microstructure outside the invention) correspond to composition 3.
  • the number, the surface fraction and the size distribution of eutectic precipitates Mg 2 Si and AlFeMnSi were measured by image analysis.
  • samples were prepared by an automatic continuous butt MIG welding shipyard company, with a 45 ° symmetrical chamfer with respect to the vertical to a thickness of 6 mm, with wire alloying 5183. The welding was carried out parallel to the rolling direction.
