Abstract (en)
[origin: CA3037115A1] The invention relates to a method for producing a hot-worked product made of an aluminium alloy composed, in wt%, of Mg: 3.8-4.2; Mn: 0.3-0.8 and preferably 0.5-0.7, Sc: 0.1-0.3; Zn: 0.1-0.4; Ti: 0.01-0.05; Zr: 0.07-0.15; Cr: <0.01; Fe: <0.15; Si <0.1; wherein the homogenisation is carried out at a temperature of between 370°C and 450°C, for between 2 and 50 hours, such that the equivalent time at 400°C is between 5 and 100 hours, and the hot deformation is carried out at an initial temperature of between 350°C and 450°C. The invention also relates to hot-worked products obtained by the method according to the invention, in particular sheets with a thickness of less than 12mm. The products according to the invention are advantageous as they offer a better compromise in terms of mechanical strength, toughness and hot-formability.
