| titleOfInvention | The manufacturing method of aluminum alloy die forgings |
| abstract | The manufacturing method of aluminum alloy die forgings, it is related to a kind of manufacturing method of AL-Cu-Mg alloy die forgings.The present invention is to provide for a kind of manufacturing method of overlength super large-scale aluminium alloy propeller blade aluminum alloy die forgings, to improve intensity, wearability, corrosion resistance and the fracture toughness of propeller blade, blade service life is made to increase.This method is as follows：One, the heating of aluminium alloy cast ingot；Two, wedge type blank；Three, forging；Four, by forging lose elution fat, in acid tank in and whiten, quenching and preserving heat, single-stage aging are to get aluminum alloy die forgings.A kind of overlength super large-scale aluminium alloy propeller blade forging part produced by the present invention not only meets standard requirement, and improve the performance of propeller blade, the features such as improving intensity, wearability, corrosion resistance and the fracture toughness of military propeller blade, improve the service life of propeller blade. |
