摘　　要：为了研究5083铝合金板材的超塑气胀成形性能,通过单向拉伸实验测试了5083合金在485℃、505℃、525℃温度下的应力-应变曲线,对不同温度条件下的材料显微组织进行了分析,并通过Abaqus有限元模拟软件对工艺路线进行优化,确定了锥筒形零件的超塑成形工艺路线,试制了5083铝合金锥筒形零件。试验结果表明,在温度485℃条件下对5083铝合金薄板进行超塑气胀成形,锥筒零件成形结果良好,最大减薄率为50%。In order to research superplastic forming performance of 5083 aluminum alloy sheet,experiments on tensile properties of 5083 aluminum alloys under different temperature of 485℃,505℃,525℃were carried out with the static material test system,the mechanical properties and microstructure of the high temperature were studied by microstructure analysis,thus the best process route of superplastic forming was established.The superplastic forming process of 5038 aluminum alloy part was simulated using Abaqus software,and the superplastic forming experiment was conducted.Tests showed that the bulging process under the temperature of 485℃will conduct a better forming part and the Maximum thinning ratio can reach to 50%.
