摘要
采用正交试验法研究了热轧复合工艺（包括加热温度、保温时间、热轧复合总加工率和道次加工率分配方式）对界面结合强度的影响，并应用金相显微镜及扫描电镜（ＳＥＭ）分析了界面的结合特性，确定了高阻尼铝合金层压板热轧复合的较优工艺：热轧复合加热温度３５０℃，保温时间１ｈ，总轧制加工率７５％，第一、二道次加工率之和为３５％左右。
The hot roll bonding is a key procedure to produce high damping laminate aluminium alloy sheets. The influences of hot roll bonding technologies involving heating temperature, holding time, total reduction ratio and reduction ratio per operation on interfacial bonding strength of various layers in the composite were studied by means of orthogonal test method. The interfacial characteristics between various bonding layers were analysed with metalloscope and scanning electron microscope. The optimum technologies for manufacturing hot roll bonding high damping laminate aluminium alloy sheets were determined, that is, heating temperature 350 ℃, holding time 1 h, total reduction ratio 75%, summary reduction ratio of the first and second operations 35%.
