Abstract
Though roll bonding is used to manufacture clad sheets in industries, the bonding criterion of layers has not been fully understood. This paper proposes that same speeds and accelerations are necessary conditions for bonding. Al/Cu/Al stacked sheets were cold rolled and changes in layer speeds and bonding status were investigated. Cu layer entered the roll bite at higher speed than Al layers. In cases without bonding, Cu layer always moved at higher speed than Al layers. In cases bonding was attained, Al layers accelerated and caught up with the Cu layer, then the three layers moved at same speed for a certain distance, then they were bonded together.
