Embodiment Construction
[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0050] The present invention provides such as Figure 1-10 A heat treatment method for aluminum alloy deformation shown, comprising the following steps:
[0051] S1: solution treatment, placing the aluminum alloy workpiece in a salt bath furnace at 455±2°C for 1 hour, and then placing the aluminum alloy workpiece in a quenching device for rapid water cooling, and the water cooling transfer time is less than 10s;
[0052] S2: cold ro...
