摘要

Microstructural evolution of infrared brazed Ti_(5o)Ni_(50) shape memory alloy and Ti-15-3 using BAg-8 and Ticusil? active braze alloys is performed in the study. Only Ticusil? active braze readily wets both Ti_(50) Ni_(50) and Ti-15-3 substrates. The wettability of Ag-Cu braze on Ti_(50) Ni_(50) substrate is improved by adding 4. 5wt% Ti into the braze alloy. The brazed Ti_(50)Ni_(50)/BAg-8/Ti-15-3 joint is mainly comprised of Ag-rich matrix and Cu-Ti intermetallics. The formation of interfacial Cu-(Ni)-Ti intermetallic phases is attributed to the wetting of both substrates. The brazed Ti_(50)Ni_(50)/ Ticusil?/Ti-15-3 joint shows more vigorous reaction among filler metal and both substrates, resulting in forming huge amount of Cu-Ni-Ti intermetallic compounds in the joint.
