    Abstract:

    In order to explore a new rapid prototyping technique using TC4 alloying sheet as molding material, the laminated forming samples were prepared with self-made Ti-based rapidly solidified brazing ribbons by means of high frequency induction brazing technology. The tensile strength and interfacial microstructure of the brazed joints were examined and analyzed. The results shows that the tensile strength of the amorphous forming sample is higher than TC4, while the crystalline one is lower than TC4, both of the brazed joints consist of (Ti,Zr)2(Cu,Ni)+(Ti,Zr)ss eutectic, Zr-rich solid solution of a-Ti. The tensile fracture shows that the fractures in the joints is brittle with herringbone.
