The experiments produced respectively al clad plate by impact & cold press methods under normal temperature . this paper studied the rules of sawtooth distortion , inspected the fibre structure and bond strength of samples , found technics parameters of produce clad plate and analyzed their infections on bond strength 分别利用冲击法和静压法在常温下制备了覆al复合钢板，研究了这两种复合钢板的锯齿变形规律，检测界面显微组织和结合强度，找到制备复合钢板的工艺参数，并分析其对复合钢板结合的影响。
The results indicate that if the value of press stress is over certain figure , press stress and al plate ’ s thickness have little influence on sawtooth distortion for the same kind of sawtooth ; sawtooth distortion is well - regulated under static press , while it is irregular under impact press . bottom coating make great influence on bond strength of samples which can improve the value remarkably ; bonding mechanism of clad steel is mechanism of mechanical effect that sawtooth which is hooked occludes with al plate 结果表明：同种齿型，当压应力大于一定的值时，压应力和覆板的厚度对齿形的变化影响不大；静压下齿形变化比较规则，锯齿顶端向一侧弯曲成钩状；冲压下齿形比较凌乱，锯齿的顶端没有明显的变形；后处理对试样的结合强度影响很大，打底试样由于粘结层的作用，结合强度较高；机械作用机制是复合钢板的主要复合机理，锯齿弯曲成钩状和铝板形成机械咬合。
The tests produced al clad plate by the method of static simulating rolling . this paper analyzed sawtooth distortion under different al plate ’ s thickness , static simulating rolling , impact and static stress ; inspected the fibre structure and bond strength of samples , summarized the rules of rolling 模拟静态等辊径等辊速冷扎制备了覆al复合钢板，分析了不同al厚度、静态轧制、冲击和静压对锯齿变形的影响、锯齿变形规律，检测了试样的显微组织和结合强度，总结了轧制变形规律。
