to various microstructure features. The Zn- and Al-rich phases exist in the middle brazing seam regions. However, two interface layers, CuZn3 and Al2Cu are formed on the Cu side when the Al content... the microstructure of the filler metals and the morphology of the brazing interface, respectively. Shear tests were conducted using a universal tensile test machine. The microhardness distribution......
