effects of the brazing temperature on microstructure and shear strength of the joint were investigated. The diffusion zone is found at joint interface near Al base metal,which consists of Al–Zn–Sn solid... of the brazing temperature, the shear strength at the joint interface near Al base metal rises gradually. On the contrary, that of the joint interface near Mg base metal obviously decreases.关键词:......

powder in home-made technical hood. Effects of brazing temperature and holding time on the interface structure and shear strength of joints were analyzed. The experimental results show that the interface structure is Al2O3/Ni(Ⅰzone)/Al3Ni2 (Ⅱzone)/Al3Ni+Mg2Si(Ⅲ zone)/α(Al)+Mg2Si(Ⅳ zone)/5A05 when the brazing temperature is 570 ℃ and holding time is 15 min. The maximum shear strength of joints......
