Definitions

  • the invention relates to the field of rolled or wire, such as sheets, profiles, wires or tubes, of alloy aluminum of the type AlMgMn to Mg> 3% by weight, intended for welded constructions with a high elastic limit, good resistance to fatigue and good toughness for structural applications, such as, for example, boats, industrial vehicles or frames welded bicycles.
  • the invention also relates to the use of these welded constructions for the shipbuilding, manufacturing of industrial vehicles and bicycle frames.
  • compositions for minor addition elements in particular iron, manganese and zinc, leading to a set of interesting properties. combining static mechanical characteristics, toughness, fatigue resistance, corrosion resistance and cutting deformation, this set of properties being particularly well suited to the use of these alloys for shipbuilding, commercial vehicles or welded cycle frames.
  • This set of properties is obtained by the combination of a low iron content, ⁇ 0.20%, and even 0.15%, and a manganese and zinc content such as Mn + 2Zn> 0.8% .
  • the Mn content must be> 0.72%, and preferably> 0.8%, to have sufficient mechanical characteristics, but must not exceed 1%, if we want to avoid degradation of the toughness and the resistance to fatigue.
  • the addition of zinc in combination with manganese has been shown to have a beneficial effect on the mechanical properties of the sheets and welded joints. However, it is better not to exceed 0.4%, as this can cause problems with welding.
  • Magnesium is maintained> 4.3% because it has a favorable effect on elastic limit and resistance to fatigue, but above 5% corrosion resistance is less good.
  • the addition of Cu and Cr are also favorable at the elastic limit, but Cr is preferably kept ⁇ 0.15% to maintain good resistance to fatigue.
  • the mechanical resistance of the sheets depends both on the content of magnesium in solid solution and dispersoids in manganese. It was found that the volume fraction of these dispersoids, which is linked to the iron and manganese contents, should preferably be kept above 1.2%. This volume fraction is calculated from the average of surface fractions measured on polished sections produced in the 3 directions (length, width and thickness) by scanning electron microscopy and image analysis.
  • the products according to the invention can be products rolled or spun such as hot rolled or cold, wires, profiles or tubes spun possibly re-stretched.
  • the sheets according to the invention assembled by butt welding using a MIG or TIG process and with a chamfer of the order of 45 ° over approximately 2/3 of the thickness, are present in the area welded an elastic limit R 0.2 which can be at least 25 MPa higher than that of a conventional alloy having the same magnesium content, ie a gain of the order of 20%.
  • the mechanical resistance of the welded joints was measured from these sheets under the following conditions: automatic continuous butt MIG welding, with a symmetrical chamfer of slope 45 ° relative to the vertical over a thickness of 4 mm and wire 5183 alloy intake.
  • the mechanical characteristics (tensile strength Rm, elastic limit R 0.2 ) were obtained by traction on test pieces standardized by the Norwegian inspection body DNV for shipbuilding, length 140 mm, width 35 mm, the weld bead of width 15 mm being in the center and the length of the narrow part of the test piece being 27 mm, ie the sum of the width of the bead and twice the thickness (15 + 12 mm).
  • the volume fractions of manganese dispersoids were also measured.
  • the elastic limit of the welded samples according to the present invention refers to an increase between 15 and 35 MPa.
  • the sheets according to the invention have a fatigue resistance at least as good as that of sheets in classic 5083.
