The invention discloses a heat treatment method for aluminum alloy forcing shaping and an aluminum alloy section for aviation, and relates to the technical field of aluminum alloy machining. The heattreatment method for aluminum alloy forcing shaping provided by the embodiment comprises the following steps that an aluminum alloy cast rod is extruded to obtain an extruded section; an aluminum alloy forcing shaping device is adopted to enable the extruded section to be fixed to be linear, then quenching treatment is carried out, and a quenched section is obtained; stretching treatment and bending treatment are carried out on the quenched section, and a shaped section is obtained; and aging treatment is carried out on the shaped section. According to the method, the problem that the aluminumalloy subjected to quenching can bend and deform can be effectively solved; and the prepared aluminum alloy section for the aviation is good in straightness and meets the requirement of the aviationuse.
