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.
compositions were as follows (% by weight): Ref. Mg Cu Mn Fe Cr Zn Ti Zr 0 4.40 ⁇ 0.01 0.50 0.27 0.09 0.01 0.01 1 4.68 ⁇ 0.01 0.72 0.12 0.05 ⁇ 0.01 0.01 2 4.56 ⁇ 0.01 0.83 0.12 0.13 0.01 0.01 3 4.60 ⁇ 0.01 0.85 0.17 0.10 0.16 0.01 4 4.62 ⁇ 0.01 0.96 0.10 0.05 0.02 0.01 5 4.80 0.09 0.80 0.11 0.03 0.02 0.01 6 4.72 ⁇ 0.01 0.87 0.13 0.03 0.02 0.01 0.11 7 4.88 0.05 0.78 0.16 0.02 0.01 0.09 8 4.92 0.06 0.94 0.08 0.02 0.19 0.01 9 4.69 ⁇ 0.01 0.72 0.07 0.02 0.10 0.01 10 4.71 ⁇ 0.01 0.82 0.06 0.02 ⁇ 0.01 0.01 11 4.73 ⁇ 0.01 0.95 0.17 0.03 ⁇ 0.01 0.01 12 4.70 ⁇ 0.01 0.92 0.22 0.03 0.01 0.01 0.01
the samples all have, after rolling, an elastic limit R 0.2 > 220 MPa in the direction L.
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 R m , elastic limit R 0.2 ) were obtained by traction on test pieces standardized by the Norwegian inspection body DNV for shipbuilding, 140 mm long, 35 mm wide, the weld bead 15 mm wide 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 results are as follows (in MPa for the resistances and% for the fractions): Ref. R m R 0.2 fractions 0 285 131 0.62 1 292 144 1.2 2 302 150 1.4 3 300 146 1.6 4 310 158 1.7 5 309 149 1.4 6 305 155 1.5 7 315 166 1.3 8 318 164 1.9 9 310 153 1.5 10 312 150 1.5 11 315 153 1.6 12 315 151 1.5
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.
