Abstract (en)
The invention relates to a method of manufacturing an AIMgSc-series aluminium alloy product, the method comprising the step of cooling said AIMgSc-series aluminium alloy product from a final annealing temperature to below 150°C, wherein the cooling in a first temperature range of about 250°C to about 200°C is at an equivalent time of more than 4 hours, and wherein the cooling in a second temperature range from about 200°C to about 150°C is at an equivalent time of more than 0.2 hours, and wherein the equivalent time (t(eq)) is defined asteq=∫exp−16000/Tdtexp−1600/Trefwherein T (in degrees Kelvin) indicates the temperature of the heat treatment, which changes over the time t (in hours) and T<sub>ref</sub>(in degrees Kelvin) is the reference temperature selected at 473K.
