    Effect of Rolling Process on Rolled Sheet Surface Quality and Structure as well as Properties of Al-Fe Alloy Plate Blank Prepared by Electromagnetic Stirring and Solid-State Extrusion

    • 摘要: 利用电磁搅拌和固态挤压技术制备了Al-5%Fe-1.2%Si-1%Mg-0.6%Cu-0.5%Mn合金板坯, 再经不同轧制工艺轧制成合金板, 研究了其表面质量、显微组织及性能。结果表明: 在温度为460 ℃、6道次、道次压下量为2 mm工艺轧制的合金板表面质量最好; 富铁相的破碎效果随道次压下量的增大而变好; 采用温度为400 ℃、4道次、道次压下量为3 mm工艺轧制的合金板富铁相形态最圆整, 尺寸最小, 其室温下的抗拉强度和伸长率最高, 达到354.5 MPa和7.6%, 且在200~300 ℃热稳定性较好。

       

      Abstract: The alloy plate blanks of Al-5%Fe-1.2%Si-1%Mg-0.6%Cu-0.5%Mn prepared by electromagnetic stirring and solid extrusion were rolled by different rolling processes, and their surface quality, microstructure and properties were studied. The results show that the surface quality of the alloy sheet was best when the rolling temperature was 460 ℃ and reduction in six passes was 2 mm; the crushing effect of iron-rich phase became better with the increase of the pass reduction; the iron-rich phase of the alloy sheet with 400 ℃ rolling temperature and 3 mm reduction in four passes had best spherical shape and smallest size, and tensile strength at room temperature and elongation of the alloy sheet reached 354.5 MPa and 7.6% respectively, and its heat stability at 200-300 ℃ was better.
