In this paper, the interface behavior in Liquid Phase Impact Diffusion Welding (LPIDW) of Aluminum Matrix Composite has been studied. Results show that by LPI diffusion welding, the interface state between reinforcement (SiC particle) and matrix is prominent, the harmful microstructure or brittle phase can be restrained from the welded joint. Moreover, dislocation density in both matrix and interface are higher than that of parent composite, the dislocation entwists each other intensively resulted in welding the composite successfully.

In this paper, a new method for welding aluminum matrix composites is mainly described. It is liquid-phase-impact (LPI) diffusion welding, which has gained China National Patent. The results show that by liquid-phase-impact diffusion welding, when the certain amount of liquid phase alloy appears, with effect of certain impact speed, the interface of matrix-reinforcement and reinforcement-reinforcement are joined perfectly. Because the welding time is very short, the harmful phase is avoided in welded area and bad effect on the interface between the aluminum matrix and reinforcement hasn’t caused, and the work efficiency has improved enormously. With the technique, particle reinforcement aluminum matrix composite SiCp/ZL101 has welded successfully, and joint strength is about 75% of the strength of composite (as-casted), deformation less than 3%.

Transient liquid-phase(TLP) bonding of SiC particle reinforced aluminum matrix composite(SiCp/Al MMCs) ,using Cu film, Cu foil, Ni foil and Cu/Ni/Cu multilayer foil interlayer, was investigated. The effect of surface status, interlayer species and bolding time on bonding microstructure and properties were also estimated by metallographic microscope, scanning electron microscopy (SEM), X ray diffraction and tensile testing machine. The results show that adding holding time can improve shear strength of joint. Better strength of joint can be obtained due to without the effect of oxide with Cu film as interlayer, when bonding at 853K for 120min under 2MPa pressure, the shear strength of bonded joints can obtain 169.1MPa, about 81.7 percentage of the strength of base material. Best strength of joint can be obtained with Cu/Ni/Cu multilayer foil as interlayer, when bonding at 923K for 120min under 2MPa pressure, the of bonded joints can obtain 189.6MPa, about 84.6 percentage of the strength of base material.
