The liquid-phase-impacting (LPI) diffusion welding mechanism and microstructure of welded joint of aluminum matrix composite SiCp/101A have been studied. It shows that by LPI diffusion welding, the interface state between SiC particle and matrix is prominent, the harmful microstructure or brittle phase can be restrained from the welded joint. Moreover, the density of dislocation in the matrix near the interface and in the matrix are all so higher than that of parent composite, the dislocation entwists each other intensively resulted in welding the composite successfully.
