Abstract

546,820. Heat-treating aluminium alloys. ALUMINUM CO. OF AMERICA. May 3, 1940, No. 8004. Convention date, May 26, 1939. [Classes 72 and 82 (i)] To restore the working properties of spontaneusly aged aluminium alloys which they possessed immediately after solution heating and quenching without destroying the capacity to again age spontaneously, the spontaneously aged alloys are subjected for a period between a few seconds and five minutes to a temperature of 225‹ C. or above, but below the temperature at which they are normally annealed, e.g. 300‹ C., and then rapidly cooled. The treatment of an alloy containing 3.95 per cent. of copper, 0.55 of manganese, 0.54 of magnesium, 0.51 of silicon and 0.45 of iron for minute in a salt bath having a temperature of 250‹ C. as well as an alloy containing 0.7 per cent. of silicon, 1.25 of magnesium and 0.25 of chromium are referred to.
