摘　　要：针对双辊铸轧工艺制备的铜铝复合板材,采用剥离试验和拉伸试验,对其力学性能进行了检测。采用扫描电镜、能谱分析仪和透射电镜等仪器对复合板界面层组织的微观形貌、结构和成分进行了分析。分析结果表明:铜铝复合板界面层的主要组成物为α-Al和Cu Al2。采用双辊铸轧工艺制备的铜铝复合板材,其剥离强度达到30 N/mm,其抗拉强度与延伸率介于同规格铜、铝板材之间。The Cu / Al composite plate was prepared by twin-roll casting. Peel testing and tensile testing were used to test mechanical properties of Cu / Al composite. The scanning electron microscope( SEM),energy dispersive spectrometer( EDS),transmission electron microscope( TEM) and other instruments were used to analyze the interface layer morphologies,structure and component. The analysis results show that the primary intermetallic compounds in the interface include α-Al and Cu Al2. The peel strength of the composite plate prepared by twin-roll casting can reach to 30 N / mm,and its tensile strength and elongation rate are between Al and Cu in the same size.
