Effects of Annealing Treatment on Microstructure and Properties of Ultra-Fine Grains 1060 Commercially Pure Aluminum Processed by Accumulative Roll Bonding(ARB)

采用累积复合轧制(ARB)技术制备超细晶1060工业纯铝,研究了热处理对超细晶工业纯铝组织和性能的影响.结果显示,室温下1060工业纯铝经过ARB8道次轧制后,材料的晶粒尺寸由轧制前的38 μm细化至0.42μm,抗拉强度增加2.5倍,延伸率下降.ARB轧制后不同道次试样经150℃x 1 h热处理后,改善了材料层间界面的结合强度,使抗拉强度略有增加..ARB5道次轧制后试样在200℃以下热处理1 h,显微组织处于回复阶段,晶粒尺寸在0.478O.58μm范围内,机械性能稳定;在200℃以上热处理时,晶粒发生再结晶,晶粒长大,材料的性能恢复.
