研究了经冷轧复合的高频电缆用铜／铝复合带材在退火过程中界面组织的演变规律。结果表明：随着退火温度的升高，在退火过程中铜／铝复合带冶金结合界面组织的生成和生长速度加快；随时间的延长，组织演变过程的4个阶段为孕育期、局部区域形成岛状新生相、扩散层发生横向→纵向→横向生长、新金属间化合物形成和扩散层增厚。
Interface microstructure evolution of cold rolled Cu/Al laminate belt during annealing was studied. The results show that the velocity of generation and growth of the Cu/Al laminate belt metallurgical interface microstructure during annealing was quickly with increasing the annealing temperature. The evolution progress constituted of four stages, which were the incubation period, the island-like new born phase in some area, the transvers→longitudinal→transvers growth of diffusion layer, the formation of a new intermetallic compound and thickening of diffusion layer.
