Summary:The invention discloses a pre-strengthened aluminum alloy short-process hot forging forming technology. The technology comprises the steps that an aluminum alloy bar is prepared, wherein cast aluminum alloy is made into a blank; the blank is subjected to solution treatment and pre-strengthening treatment, and an aluminum alloy bar is obtained; the aluminum alloy bar is heated to the temperature close to the phase transformation point temperature, and heat preservation is conducted for a certain time; transferring the heated and insulated aluminum alloy blank into a forging die for forging and forming to obtain a forge piece; and cooling the forge piece, trimming the forge piece, and machining the forge piece to obtain the required aluminum alloy part. The method has the beneficial effects that the process route of aluminum alloy bar preparation, heat preservation treatment before forging and forging deformation is adopted. Original three-time heating is reduced to one-time heating, so that the aluminum alloy
