摘要： 采用异步轧制复合工艺制备了铜/铝双金属复合板,分析了轧制工艺参数对复合板变形行为的影响,结合轧制变形区金属受力状态探讨了复合过程中的金属变形及流动规律.结果表明:异步轧制变形区内界面摩擦剪切作用直接影响母材的受力状态,共同变形区内双金属间的搓轧作用对金属流动及结合效果影响最大.异步速比越大,硬质金属变形越大.总压下率增大时,组元金属压下率均呈正比关系增加,且软、硬两种金属的压下率差值越来越小.

Abstract: The effect of roll bonding parameters on deformation distribution of Cu/Al bimetal clad sheets fabricated by asymmetrical roll bonding was investigated. The stress state of the deformation zone was developed and used to analyze metal flow during the roll bonding process. The deformation proportion of hard component metal in the whole clad sheet increased as asynchronous speed ratio increased. Shear friction directly impacted the stress state of body metals, and cross shear had the most influence on metal flow and bonding strength. The reduction of both layers was directly proportional to total reduction, and the difference between hard and soft metals gradually diminished.
