Abstract
A method for fabricating an article from an aluminum alloy is provided. The method includes providing an aluminum alloy containing at least 0.04 wt % Sc, at least 0.5 wt % Mn, at least 0.5 wt % Zr, at least 0.05 wt % Mg, and at least 90 wt % Al; casting the alloy into a sheet; subjecting the cast alloy to a thermal cycle which includes raising the temperature of the alloy along a first temperature gradient, holding the temperature of the alloy at a temperature T for a period of time t, and reducing the temperature of the alloy along a second temperature gradient; and utilizing the sheet in a brazing operation.
