With the advantages of respective component materials

metal laminates can achieve comprehensive performance that cannot be satisfied by a single metal

which are one of the most important metal structural materials in recent years and have been widely used in the fields of aerospace

defense and military industry

transportation

and equipment manufacturing. Rolling method is one of the main preparation methods of metal laminates

and has the advantages of stable and continuous production. In this paper

the research progress of metal laminates roll bonding process at home and abroad is reviewed

and the currently recognized metal laminates roll bonding hypotheses including mechanical meshing theory and metal bonding theory are discussed. The advantages

disadvantages

and application scope of hot rolling

cold rolling

differential temperature rolling

accumulative rolling

asymmetrical rolling

and other bonding processes are classified and summarized. The characteristics of metal laminates roll bonding technologies are analyzed by theoretical analysis of slab method

stream function method

and upper bound method. Aiming at the connection problem of the interface to be bonded in numerical simulation

the interface processing models such as bonding model and common node model are briefly described. The bonding criteria of the fixed value or functional relationship of stress field

strain field

and velocity field are summarized. Based on the shortcomings of the current roll bonding process

the internationally pioneered corrugated-flat rolling (CFR) process proposed by the research team is introduced

which has low residual stress

good shape

and high bonding strength. Besides

the prospect of the future research emphases of roll bonding process is put forward.
