通过自制电场固溶所需的高压电场源，利用 MULTISIM 软件对自制电场源中电容器的充电过程进行模拟，并采用万用表测出电场源输出的电压值为5.2 kV ；研究7050铝合金在不同固溶电场强度下的时效成形，考察普通固溶处理＋时效成形和电场固溶处理＋时效成形后合金的回弹率以及力学性能的差异。结果表明，与普通固溶处理相比，电场固溶处理能够进一步提高过饱和固溶体的浓度，时效成形过程中会促进应力松弛，使合金的回弹率降低；同时，过饱和固溶体浓度的提高还会促进时效成形过程中第二相的析出，从而改善合金的力学性能，使合金的延伸率有较大幅度的提高，而抗拉强度基本不变。

In this paper ,the electric field solution needed high voltage electric field source was self-made ,electric source of capaci-tor charging process was simulated by MULTISIM software ,using the multimeter to measure electric field source output voltage is 5.2kV.The age forming of 7050 aluminum alloy subjected to different the electric field solution was investigated , The differ-ence of springback and mechanical properies after treatment with solid solution and without electric field was also studied.Results show that ,compared with solid solution treatment ,electric field solid solution treatment can further improve the concentration of the supersaturated solid solution , the stress relaxation will be promoted during the age forming process , resulting in reduced springback ratio ;and the improvement of supersaturated solid solution concentration also will promote forming the second phase precipitation in the process of age forming so as to improve the mechanical properties of alloy ,which will madee alloy elongation greatly improved ,while the tensile strength basically remain unchanged.
