Definitions
- the invention relates to the technical field of alloy sheets aluminum of the AlMg type and more particularly an alloy 5083 or 5086 according to standard EN 573-3, intended for welded constructions such as fixed tanks or mobile and in particular road transport tanks or railways of solid or liquid materials.
- the aim of the present invention is therefore to improve this trade-off between elongation and breaking strength while ensuring satisfactory corrosion resistance and manufacturing range as simple and reliable as possible.
- Japanese patent application JP 06-212373 shows examples of AlMgMn alloy sheets presenting a good compromise between elongation and strength but manufacturing by hot rolling requires minimum exit temperature of the rolling mill at 450 ° C., which requires a rate of fast manufacturing and minimal lubrication and does not allow therefore not a reliable and economical manufacture of bands.
- Japanese patent application JP 06-93365 also shows AlMgMn alloy sheets with mechanical characteristics meeting the intended objective, but their manufacture intervene a complicated and expensive range, comprising a hot rolling followed by intermediate annealing, warm rolling and final annealing.
- the invention relates to a fusion-welded sheet construction of AlMg alloy with thickness> 2mm, as defined in the claims 1 and 12, as well as its use according to claims 10, 11, 21 and 22.
- the zinc content is preferably between 0.07 and 0.2%.
- the iron content is between 0.20 and 0.45% and more than half the manganese content.
- the sheets according to the invention are produced by semi-continuous casting, preferably without final annealing and by hot rolling with a temperature of outlet of the rolling mill between 300 and 370 ° C, and preferably between 320 and 360 ° C.
- Magnesium provides good resistance mechanical, but too high a content decreases the resistance to corrosion, which would limit the use of tanks made with such alloys.
- Manganese improves tensile strength, but a too high content leads to a decrease in elongation.
- an addition of chromium provided that it does not exceed 0.15%, makes it possible to increase both the elongation A and the resistance to corrosion, and an addition of copper of less than 0.25% leads to an increase in R m .
- the iron content must be below 0.45% in order to avoid the formation of primary phases, the presence of which results in an unacceptable deterioration of the mechanical characteristics of the sheet.
- the applicant has surprisingly demonstrated that it is advantageous to choose an iron content close to 0.45%, because during casting, almost all of the iron forms eutectic precipitates of the AlMnFe type. It is noted, which is contrary to what is usually observed, that a large fraction of these eutectic precipitates improves the ductility of the sheet and that it is desirable that this fraction is at least 0.7%.
- the fraction of manganese dispersoids in the final sheet must remain low, and below 1.5 times the fraction of eutectics, which is expressed by the relationship Fe> 0.5Mn.
- the volume fractions of eutectic precipitates and dispersoids are measured by the surface fractions calculated on micrographs by well known metallographic techniques, for example by scanning electron microscopy and image analysis on a polished section of a sheet sample. This possibility of choosing an iron content which is not too low makes it possible to choose a less pure and therefore less expensive base metal, while having good mechanical characteristics.
- the composition according to the invention it is possible to obtain sheets of thickness> 2 mm having a breaking strength R m > 275 MPa, an elongation A> 17.5% and a product A x R m > 6500, by rolling without final annealing at a temperature> 250 ° C, and, more particularly, by hot rolling and in large width, for example> 2200 mm.
- the temperature at the outlet of the hot rolling mill is less than 400 ° C., and preferably at 370 ° C. or even at 350 ° C.
- the sheets according to the invention can be used for welded constructions, such as fixed tanks or mobile, for example rail or road tanks, but also road and rail transport containers and / or maritime, as well as welded and / or forged wheels for automobile or truck.
- These sheets can be welded by all the means usually used for this type of alloy, in particular by butt welding using a MIG process or TIG and with a chamfer of the order of 45 ° on approximately the 2/3 of the thickness. It is beneficial for all of these applications, to be able to have very wide sheets, in particular of width greater than 2200 mm.
- Alloys 0 to 4 and 13 have a composition outside the invention (alloy 0 representing a composition of 5083), the others alloys a composition according to the invention.
- MIG welding tests carried out by MIG butt welding with a 45 ° chamfer on 2/3 of the thickness have shown a weldability similar to that of sheets of alloys 5083 and 5086 of usual composition.

Description
Cette possibilité de choisir une teneur en fer pas trop basse permet de choisir un métal de base moins pur et donc moins cher, tout en ayant de bonnes caractéristiques mécaniques.
