摘　　要：在室温条件下对1060工业纯铝进行7道次的累积叠轧焊轧制,将综合力学性能较好的ARB道次试样进行热处理实验研究,分析经过ARB剧烈塑性变形的金属材料在热处理条件下其微观组织与力学性能的变化。实验结果表明,ARB 5道次材料的综合力学性能较好,其抗拉强度为210 MPa,延伸率为9.3%。ARB 5道次试样在200℃以下温度条件下进行热处理,其拉伸性能稳定,显微组织处于回复阶段,超细晶材料组织和性能具有良好的稳定性。1060 industrial pure aluminum was rolled by cumulative roll welding for 7 passes at room temperature.The ARB pass samples with good mechanical properties were investigated by heat treatment experiments.The microstructure and mechanical properties of the metal materials with severe plastic deformation of ARB were analyzed under heat treatment conditions.The results show that the composite mechanical properties of ARB5 pass material are good,with the tensile strength of 210MPa and the elongation of 9.3%.The tensile properties of ARB5 pass specimens are stable and the microstructure is in the recovery stage after heat treatment at the temperature below 200℃.The microstructure and properties of the ultrafine grain material have good stability.
