摘　　要：采用热轧复合的方法,将纯铝板包覆在镁合金铸轧板坯表面,多道次大压下轧制工艺制备出了镁铝复合板,研究了轧制温度、道次压下量及热处理工艺对复合板组织和力学性能的影响。结果表明当轧制温度为400℃,道次加工率为30%～35%时,镁、铝板材可以实现良好的复合；随着复合板材热处理温度的提高,复合界面脆化程度增大,板材力学性能下降。Pure aluminum plate was coated on magnesium alloy casting slab surface. Magnesium aluminum composite plate was prepared by composite method of hot rolling （the rolling technology of multi-pass and big reduction）. The influences of rolling temperature, pass reduction and heat treatment process on microstructure and mechanical properties of clad sheet were studied. The results show that the magnesium sheet and aluminum sheet can achieve excellent bonding at the rolling temperature of 400℃ and pass reduction rate of 30%-35%; the brittleness increases on the composite interface, and the mechanical properties of sheet descend with the increase of heat treatment temperature of the composite plate.
