FIELD: metallurgy.
SUBSTANCE: invention relates to aluminum alloys used in automotive industry. Method of producing article from aluminum alloy involves forming a sheet from dispersion-hardening thermally treated aluminum alloy to obtain from aluminum alloy molded article having one or more parts; heating at least one part of molded article from aluminum alloy, having one or more parts, two or more times to heat treatment temperature from 250 to 300 °C at heating rate from 10 to 220 °C/s and maintaining each heat treatment temperature for 60 s or less, wherein at least one part of molded article from aluminum alloy contains dispersion-hardening thermally treated aluminum alloy.
EFFECT: invention is aimed at increasing strength of articles from thermally treated precipitation-hardening aluminum alloys.
