Abstract
A method of producing an Al—Mg—Si-based aluminum alloy forged product, includes a solution heat treatment step of performing a solution heat treatment for heating the forged product obtained in the forging step at a temperature rising rate of 5.0° C./min or more from 20° C. to 500° C. and holding the forged product at 530° C. to 560° C. for 0.3 hours to 3 hours, a quench treatment step of quenching the forged product in a water tank by bringing an entire surface of the forged product into contact with quenching water within 5 seconds to 60 seconds after the solution heat treatment step for more than 5 minutes and not more than 40 minutes, and an aging treatment step of performing an aging treatment by heating the forged product after the quench treatment step at a temperature of 180° C. to 220° C. for 0.5 hours to 1.5 hours.
