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......
