Description
Technical Field
The invention relates to the technical field of aluminum alloy processing, in particular to a heat treatment method for forced shaping of aluminum alloy and an aluminum alloy profile for aviation.
Background
The current trend toward larger, faster, and longer-lived commercial aircraft has led aircraft manufacturers to place greater demands on the design and material properties of aircraft structural members through intense market competition. The design emphasis of aircraft has evolved from initial static strength designs to safe life designs, safe life/failure safety designs, safe life/damage tolerance designs, and durability/damage tolerance designs. With the upsizing of airplanes, the sizes of structural members of airplanes become larger correspondingly, the structural members are developed towards lighter, larger, higher performance, more reliable, longer service life and lower cost, and the whole structural members gradually replace assembly structures. Therefore, the requirements for the performance of the structural material, uniformity and dimensional accuracy thereof are increasingly high.
The 2-series alloy section is an aviation aircraft structural material widely applied, and at present, many researches on 2-series aluminum alloy materials are carried out, but most of the researches are focused on methods for improving the performance of the aluminum alloy: for example, (1) the alloy components are adjusted, including microalloying, optimizing the content of alloy elements, adding rare earth elements, reducing the content of impurities and the like; (2) improving the heat treatment system of the alloy, adjusting the microstructure of the alloy, and controlling the appearance, quantity and distribution of precipitated phases; (3) an advanced alloy preparation method is adopted. At present, the thermomechanical treatment is an effective method for changing the precipitation condition of the alloy, but after the 2-series alloy is subjected to solution quenching treatment, the bending deformation of the section can occur, because the reasonable quenching parameters are difficult to determine particularly for complex sections due to improper setting of the quenching water amount formula in the quenching process, and the stress concentration and the section deformation can be caused by nonuniform quenching. Although this problem can be properly solved by the subsequent stretch-straightening treatment, the deformation problem occurs after the profile is left for a while.
Therefore, the problem to be solved urgently at present is to search a heat treatment method for preventing the bending deformation of the aluminum alloy section in the quenching and aging processes so as to meet the size requirement of the aviation section.
