Forging and heat treatment process for aero-engine aluminium alloy vane

The invention provides a forging and heat treatment process for an aero-engine aluminium alloy vane. Through the adoption of the process, the mechanical property of an Al-Cu-Mn-Zr-V-Ti vane forge piece can effectively improved so as to meet the technical requirements of design and application. The process comprises the following steps: firstly, heating and forging the Al-Cu-Mn-Zr-V-Ti vane blank to obtain an aluminium alloy vane forge piece and then performing heat treatment on the aluminium alloy vane forge piece. The treatment process is characterized in that heating and forging operation comprise the following steps: heating the aluminium alloy vane blank to 455-465 DEG C in a heating furnace, performing heat preservation for 4.5-5.5 hours, and placing the aluminium alloy vane blank on a press machine for die forging deformation so as to obtain the aluminium alloy vane forge piece, wherein the die forging deformation is controlled to be 20-60%.
