Embodiment 1
[0039] For the α-Mg single-phase Mg-Li alloy, its composition and mass percentage are Li: 5.0%, Al: 1.0%, and the total amount of unavoidable impurities such as Fe, Cu, Ni, Mn, Si is less than 0.03%, The balance is Mg. For the β-Li single-phase Mg-Li alloy, its composition and mass percentage are: Li: 12.0%, Al: 1.0%, and the total amount of unavoidable impurities such as Fe, Cu, Ni, Mn, Si, etc. is less than 0.03% , the balance being Mg. The initial thickness of the plates is 2mm.
[0040] The cumulative rolling and annealing process of α / β magnesium-lithium alloy composite plate:
[0041] (a) Cut the two magnesium-lithium alloy plates into two pieces of equal size. Firstly, the surface is cleaned, that is, it is cleaned with dilute hydrochloric acid to remove large oil stains on the surface of the alloy; then polished with fine sandpaper to remove oxides on the surface of the alloy; then cleaned with acetone to further remove oil stains on the surface of the alloy; finall...
