Abstract The metallurgical process of the fillets formed during aluminum brazing has been discussed. The dissolve of base-metal into the liquid fillet metal was first beginning at its crystal boundaries, owing to the homogenization of the liquid phase, Si permeates into the boundaries. Meanwhile, Si in the liquid diffused into Al granules, thus the a-phase formed.
