模压变形5052铝合金的显微组织与室温拉伸性能
Microstructure and Tensile Properties at Room Temperature of 5052 Aluminum Alloy Processed by Groove Pressing Deformation
摘 要
对5052铝合金板进行了多道次模压(GP)变形, 研究了GP变形道次对其显微组织和室温拉伸性能的影响。结果表明: 该铝合金的平均晶粒尺寸随GP变形道次的增加而减小, 4道次变形后平均晶粒尺寸由未变形的43.2 μm细化到约1.1 μm; 抗拉强度随GP变形道次的增加而单调递增, 伸长率则先快速下降后缓慢升高; 4道次GP变形能使5052铝合金在提高抗拉强度的同时保持良好的塑性。

Abstract
The 5052 aluminum alloy sheets were processed by the groove pressing (GP) deformation for multi-passes, and the effects of the GP deformation passes on the microstructure and tensile properties at room temperature were studied. The results show that the average grain size of the aluminum alloy decreased with the increase of the GP deformation passes. After deformation for four passes the average grain size was reduced from undeformed 43.2 μm to about 1.1 μm. The tensile strength monotonously increased with the increase of the GP deformation passes while the elongation first decreased rapidly then increased slowly. The process of GP deformation for four passes can improve the tensile strength and simultaneously maintained the good plasticity of the 5052 aluminum alloy.
