摘要: The invention belongs to the technical field of heat treatment aluminum alloys, and specifically relates an aging method for a high-zinc alloy containing scandium. comprises following steps: firstly, preserving scandium 3.5-4.5h at temperature 455-465 DEG C, then, 10s later after preservation, transferring into water room quenching 5min, further carrying out two-stage treatment: 5.5-6.5h 100-120 heating up 155-175 C in furnace 6-8h, finally cooling temperature, thereby obtaining subjected treatment. With provided by invention, hardness, tensile strength, yield strength elongation are all improved remarkably, application range industrial circle is extended.
