摘　　要：利用TEM观察了1235超薄双零铝箔坯料中Al-Fe-Si第二相粒子在轧制过程中的演化行为。结果表明,随着轧制过程的进行,块状第二相粒子在轧制剪应力的作用下被拉长,同时在拉长的块状第二相粒子周围富集了许多从基体上脱落的球形小颗粒第二相粒子。导致第二相颗粒、溶解球化的主要原因是扩散引起的,高密度的位错及空位等晶体缺陷是第二相粒子回溶的主要通道。The evolution behavior of Al-Fe-Si secondary phase particles in 1235 ultra-thin double zero foil blank during rolling process was observed by TEM. The results show that bulk secondary phase particles are elongated under the shear stress during rolling process. Meanwhile many small spherical secondary phase particles are concentrated around the elongated bulk secondary phase particles. The major reason for secondary phase particles dissolution and spheroidizing is diffusion process. In addition, crystal defects such as high density dislocations and vacancies are the main channels of secondary phase particles dissolution.
