Al-3Fe alloy was prepared by the method of continuous rheo-extrusion, and the effect of rolling deformation on the microstructure and the property of the rheo-extruded Al-3Fe alloy was studied by means of scanning electron microscope (SEM), transmission electron microscopy (TEM) and tensile test. The rheo-extruded pure Al was also prepared for comparison. The results showed that the rolling deformation could further refine the grain size of the rheo-extruded Al-Fe alloy, and reduce the size of the Al-Fe phase. Due to the present of nanosized and sub-micron sized Al₃Fe phase, the strength of rheo-extruded Al-Fe alloy is significantly higher than that of rheo-extruded pure Al, and this advantage has been maintained during subsequently rolling deformation. Moreover, the strength and the elongation are simultaneously increased when the rolling reduction exceeds 60% for Al-Fe alloy and pure Al. Both of Al-Fe alloy and pure Al have the best comprehensive mechanical property when the rolling reduction reaches 90%. The main contribution is attributed to the grain refinement and the formation of high fraction substructure.

采用连续流变挤压法制备Al-3Fe合金，并通过扫描电子显微镜（SEM），透射电子学研究了轧制变形对流变挤压Al-3Fe合金组织和性能的影响。显微镜（TEM）和拉伸试验。还制备了流变挤出的纯铝用于比较。结果表明，轧制变形可以进一步细化流变挤压的Al-Fe合金的晶粒尺寸，并减小Al-Fe相的尺寸。由于存在纳米级和亚微米级的Al ₃相对于流变挤压的纯铝，Fe相的强度明显高于流变挤压的Al-Fe合金，并且在随后的轧制变形过程中保持了这一优势。此外，当Al-Fe合金和纯Al的压下率超过60％时，强度和伸长率同时增加。当压下率达到90％时，Al-Fe合金和纯Al都具有最佳的综合机械性能。主要贡献在于晶粒细化和高分数子结构的形成。
