研究了异温轧制复合工艺制度对钢和铝复合板初结合强度的影响。结果表明，轧制变形程度和铝层加热温度都是影响复合板初结合强度的主要因素。利用扫描电镜观察分析复合界面形貌，并对微区成分分析证明，异温轧制复合有不同于室温固相复合的结合机制。 The effect of different temperature rolling process on the initial bond strength of steel and aluminum composite plate was studied. The results show that both the degree of rolling deformation and the heating temperature of the aluminum layer are the main factors affecting the initial bond strength of the composite plate. Scanning electron microscopy (SEM) was used to analyze the morphology of the composite interface. The analysis of the microstructure showed that the bonding mechanism was different from that of room temperature solid phase composite in allothermal rolling.
