高性能铜/铝复合排的制备及界面机理
Preparation of High-performance Cu-Al Composite Row and Its Interface Bonding Mechanism
摘要
Abstract
Cu-Al composite row was prepared by solid-liquid bonding method and cast-rolling technique. Different processes affecting interfacial strength were studied. The interface structure and bonding mechanism of Cu-Al composite row were analyzed. The results show that when the heat treatment temperature is 300℃, for lh, the interfacial bonding strength is the highest. The bonding strength increases after multiple thermal cycling. Energy Dispersive Spectroscopy(EDS) and X-ray Diffraction (XRD) analysis show that the interface diffusion layer generates the intermetallic compounds Al2Cu, AlCu and ALCu9, phase, which increase the interfacial hardness. Cu-Al composite row prepared by this method has excellent mechanical properties and electrical conductivity; the tensile strength reaches 98 MPa; the resistance rate is 0.0216 ×10-6Ω·m.关键词
