摘要
采用冷轧复合法制备钛/钢层状复合板,研究轧制压下率、轧制道次、表面粗糙度、原材料状态和轧制速率对钛/钢层状复合板界面结合强度的影响。结果表明:界面作用力和轧制力对界面的作用时间是影响钛/钢层状复合板界面结合强度的主要因素。轧制压下率、表面粗糙度和原材料状态通过影响界面作用力来影响钛/钢层状复合板的界面结合强度;轧制速率通过影响轧制力对界面的作用时间来影响钛/钢层状复合板的界面结合强度;钛/钢层状复合板的冷轧复合效果与轧制道次无关,只有单道次轧制压下率超过临界轧制压下率时,才能实现冷轧复合。
Titanium/steel laminated composite plates were prepared by cold rolling method.The effects of rolling reduction,rolling speed,surface roughness,state of raw material and rolling pass on the interfacial bonding strength of titanium/steel laminated composite plates were studied.The results show that the interfacial action force and action time of rolling force on the interface are the main parameters affecting the interfacial bonding strength of titanium/steel laminated composite plates.The rolling reduction,surface roughness and state of raw material affect the interfacial bonding strength of titanium/steel laminated composite plate through affecting the interfacial action force.The rolling speed affects the interfacial bonding strength of titanium/steel laminated composite plate through affecting the action time of rolling force on the interface.Whether the titanium/steel laminated composite plate can be cold roll bonded or not has nothing to do with the number of rolling passes,only when the rolling reduction of single pass exceeds the critical rolling reduction can the cold roll bonded be realized.
