Abstract:

6XXX series aluminum alloy is a kind of light alloy with excellent comprehensive properties of medium and high strength, easy forming, corrosion resistance,good energy absorption effect, and so on. It is also an important material for the development of automotive lightweight technology. It is very important to clarify the strengthening mechanism and control method of 6XXX series aluminum alloy from the perspective of composition-process-structure�瞤roperty relationships, so as to broaden the application range of aluminum alloy in the automotive field of our country. This paper summarizes the application of 6XXX series aluminum alloy in automobile, introduces the main strengthening mechanisms of 6XXX series aluminum alloy, and focuses on the aging process progress of 6XXX series aluminum alloy and the evolution law of precipitated phase in the aging process. The effects of microalloying elements such as Cu, Cr, Mn, Sn, Sc, Zr and Ce on the microstructures and mechanical properties of 6XXX series aluminum alloys are briefly discussed. Finally, the development of 6XXX series aluminum alloy with better comprehensive properties is prospected.
