英文摘要	The diffusion phenomenon of element Cu in the joint is observed by means of SEM and EDS to study and discuss the diffuse effect and final production of element Cu in different brazing temperature and heat dwell time. The Al-Cu eutectic brazing metal is made to braze pure aluminium matrix in vacuum. The results indicate that the diffusion of element Cu is not complete at low brazing temperature and short dwell time. It comes into being the 6 phase (Al2Cu) which is the brittlest in all Al-Cu phase and forms serious segregation on the substrate' s grain boundary. Although enhancing the brazing temperature and dwell time could improve the diffuse ability of Cu, the exorbitant brazing temperature would cause the reappearance of the θ phase. It is important to choose the best technical parameter for getting the best quality joints.
