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.

Description
Dans ce domaine, les travaux de recherche se sont surtout concentrés sur la conduite de l'opération de soudage elle-même. De plus, on a cherché, par des traitements thermomécaniques appropriés, à améliorer la tenue à la corrosion de la pièce.
La demande de brevet japonais JP 06-212373 propose, pour minimiser la réduction de la résistance mécanique due au soudage, d'utiliser un alliage contenant de 1,0 à 2,0% de Mn, de 3,0 à 6,0% de Mg et moins de 0,15% de fer. Mais, l'utilisation d'un alliage avec une teneur aussi élevée en manganèse conduit à un abaissement de la résistance à la fatigue et de la tenacité.
L'invention a pour objet des constructions soudées en alliage AlMgMn de composition (en poids %):
- Fe < 0,20
- Si < 0,25
- Zn < 0,40
- Cr < 0,25
- Cu < 0,20
- Ti < 0,20
- Zr < 0,20
avec la relation: Mn + 2Zn > 0,8
ce produit présentant dans la zone soudée une dureté > 80, HV.
Cet ensemble de propriétés est obtenu par la combinaison d'une basse teneur en fer, < 0,20%, et même 0,15%, et d'une teneur en manganèse et en zinc telle que Mn + 2Zn > 0,8%. La teneur en Mn doit être > 0,72%, et de préférence > 0,8%, pour avoir des caractéristiques mécaniques suffisantes, mais ne doit pas dépasser pour autant 1%, si on veut éviter une dégradation de la ténacité et de la résistance à la fatigue. L'addition de zinc en combinaison avec le manganèse s'est révélée avoir un effet bénéfique sur les caractéristiques mécaniques des tôles et des joints soudés. Toutefois, il vaut mieux ne pas dépasser 0,4%, car on peut alors rencontrer des problèmes au soudage.
Les tôles selon l'invention sont le plus souvent d'épaisseur supérieure à 1,5 mm. Pour les épaisseurs supérieures à 2,5 mm, elles peuvent être obtenues directement par laminage à chaud, sans nécessité d'un laminage à froid ultérieur, et, de plus, ces tôles laminées à chaud présentent à la découpe une distorsion plus faible que les tôles laminées à froid.
Les produits selon l'invention présentent une résistance à la corrosion aussi bonne que les alliages habituels à même teneur en magnésium, par exemple le 5083 de composition courante, largement utilisé dans la construction navale.
Les compositions étaient les suivantes (% en poids):
| Réf | 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 |
On a mesuré la résistance mécanique des joints soudés à partir de ces tôles dans les conditions suivantes: soudage MIG bout à bout continu automatique, avec un chanfrein symétrique de pente 45° par rapport à la verticale sur une épaisseur de 4 mm et fil d'apport en alliage 5183.
Les caractéristiques mécaniques (résistance à la rupture Rm, limite élastique R0,2) ont été obtenues par traction sur des éprouvettes normalisées par l'organisme norvégien de contrôle DNV pour la construction navale, de longueur 140 mm, de largeur 35 mm, le cordon de soudure de largeur 15 mm étant au centre et la longueur de la partie étroite de l'éprouvette étant de 27 mm, soit la somme de la largeur du cordon et de 2 fois l'épaisseur (15 + 12 mm).
On a mesuré également les fractions volumiques de dispersoïdes au manganèse.
Les résultats sont les suivants (en MPa pour les résistances et % pour les fractions):
| Réf. | Rm | R0,2 | 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 |

| 11 | 315 | 153 | 1,6 |
| 12 | 315 | 151 | 1,5 |
Les résultats ont été les suivants:
| Réf. | 106 cycles | 107 cycles | ΔK |
| 0 | 220 | 200 | 22 |
| 1 | 235 | 205 | 22 |
