摘　　要：对3004变形铝合金进行了多向锻造和时效处理,分析了它的显微组织演变,研究了力学性能和点腐蚀行为。结果表明:多向锻造和时效处理后,合金的抗拉强度高且伸长率良好,抗点腐蚀能力也有所提高。The multi-directional forging and aging treatment of 3004 wrought aluminum alloy were carried out. Evolution of the microstructure was analyzed, and mechanical properties and pitting corrosion behavior were studied. The results show that the tensile strength of the alloy is higher and elongation is good, and the pitting corrosion resistance is also enhanced after the multi-directional forging and aging treatment.
