| 摘 要： | 在室温、无润滑及总压下量相同的条件下,分别采用每道次两层叠轧和每道次三层叠轧的工艺对退火态AA1070工业纯铝板材进行了累积叠轧焊合试验,比较了最终板材界面焊合、织构和力学性能的差别。结果表明,与两层叠轧工艺相比,通过三层叠轧工艺所制备的板材金属层之间焊合状况更好,具有较强的剪切织构和轧制织构,表现出较高的伸长率和较低的抗拉强度,具有较好的综合力学性能。这些差别主要归结于三层叠轧条件下较大的道次压下量和有效剪切变形。

| Abstract: | In this study,an annealed commercial-purity aluminum sheet(AA1070) was subjected to accumulative roll-bonding(ARB) experiments at room temperature using two-layered initial strips and three-layered initial strips,respectively,with no lubrication and under the same total reduction.The differences of interface bonding,texture and mechanical properties between the final processed sheets in the two cases were investigated.The results show that the bonding between metal layers in the case of three-layered ARB is... |
