摘要:

镁/铝叠层复合板作为一种新型的叠层复合材料,利用爆炸+轧制的工艺方法生产镁/铝叠层复合板能够充分发挥镁合金和铝合金的性能优势。应用ABAQUS有限元分析软件对镁/铝爆炸复合板在不同热轧工艺下的热轧过程进行模拟,分析了轧制过程中温度、压下率对复合板宽展、等效应变及翘曲程度的影响。模拟结果表明:复合板宽展随温度的升高而略微降低,随轧制压下率的增大而增大;轧制过程中金属主要沿轧制方向进行流动,最大宽展率为3.5%;从复合板头部到尾部,节点的等效应力先升高、再维持水平、最后下降,界面最大等效应变随压下率的增加由0.164增大至0.523;轧制过程中,界面处金属温度高于两侧金属温度,轧制结束后温度由350 ℃降至237 ℃;轧制温度为350 ℃、轧制压下率为30%时,轧制效果最好。

The magnesium/aluminum laminated composite plate is a new kind of laminated composite material, and it can be produced by explosion+rolling method so as to play the advantages of magnesium alloy and aluminum alloy performance fully. The hot rolling process of Mg/Al explosive welding composite plate under different hot rolling parameters was simulated by finite element analysis ABAQUS software, and the influences of rolling temperature and reduction ratio on the broadening of plate, equivalent strain and degree of warping were analyzed. Simulation results show that the broadening of composite plate decreases slightly with the increases of temperature, and increases with the increase of rolling reduction ratio. However, during rolling process the metal mainly flows along the rolling direction, and the maximum broadening rate of composite plate is 3.5%. From the head to the end of the composite plate, the equivalent stress of the joint first increases, then maintains the level and finally falls down, and the maximum equivalent strain at interface is increased from 0.164 to 0.523 with increasing rolling reduction. Thus, the temperature at interfacial metal is higher than both sides of composite plate in the process of rolling, at the end of rolling the temperature falls down from 350 ℃ to 237 ℃. The optimum rolling quality can be obtained when rolled at 350 ℃ with rolling reduction by 30%.
