摘　　要：分别采用两道次轧制过程中中间退火和未中间退火两种工艺制备了Cu/Al复合板,研究了中间退火处理对复合板界面结合性能的影响。研究结果表明,两种工艺条件下制备的复合板界面均牢固结合,但采用中间退火处理工艺更有利于提升轧后Cu/Al复合板的结合强度。其中,采用未中间退火的两道次轧后复合板的剥离强度为28.29 MPa,而采用中间退火工艺的复合板剥离强度则达到了34.05 MPa。这是因为经过中间退火处理后进行二道次轧制制备的复合板界面由冶金结合区和物理结合区共同组成,协同作用强化了界面的结合性能。Cu/Al clad plate was prepared by intermediate annealing and non-intermediate annealing in two-pass rolling process,and the effect of intermediate annealing treatment on interface bonding properties of the clad plate was studied.The results show that the interfaces of Cu/Al clad plate prepared under the two processing conditions are firmly bonded,but the intermediate annealing process is more conducive to improving the bonding strength of the rolled Cu/Al clad plate.The peeling strength of the clad plate after two passes of rolling without intermediate annealing is 28.29 MPa,while the peeling strength of the clad plate after intermediate annealing is 34.05 MPa.This is because the interface of the clad plate prepared by two passes of rolling after intermediate annealing treatment is composed of metallurgical bonding zone and physical bonding zone,which synergistically strengthens the bonding properties of the interface.
