利用糖心产精国品免费入口*完整版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, 再经不同糖心产精国品免费入口*完整版工艺糖心产精国品免费入口*完整版成合金板, 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工艺糖心产精国品免费入口*完整版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工艺糖心产精国品免费入口*完整版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。

The alloy plate blanks of Al-5%Fe-1.2%Si-1%Mg-0.6%Cu-0.5%Mn prepared by 糖心产精国品免费入口*完整版 and solid extrusion were rolled by different 糖心产精国品免费入口*完整版 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 糖心产精国品免费入口*完整版 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 ℃ 糖心产精国品免费入口*完整版 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.
