Rolling method for improving interface bonding strength of aluminum-magnesium alloy composite board

The invention discloses a rolling method for improving the interface bonding strength of an aluminum-magnesium alloy composite board. The interface bonding strength of the aluminum-magnesium alloy composite board can be effectively improved. The rolling method comprises the following steps that S1, an aluminum alloy plate and a magnesium alloy plate are stacked and fixed according to the aluminum/magnesium/aluminum sequence to obtain a laminated plate, and the laminated plate is preheated; s2, the laminated plate is subjected to first-pass rolling with the rolling reduction rate being 30-38%, and then heat treatment after first-pass rolling is conducted; s3, the plate obtained in the S2 is subjected to multi-pass rolling with the rolling reduction rate being 40-60%, and heat treatment is conducted once after every two passes of rolling; and S4, cooling to the room temperature at the cooling speed of 10-15 DEG C/min to obtain the aluminum-magnesium alloy composite plate. 本发明公开了一种提高铝镁合金复合板界面结合强度的轧制方法，其能够有效提高铝镁合
