Abstract
Infrared brazing Ti50Ni50 shape memory alloy using pure Au and Au-20Cu as the fillers has been investigated. The Au-rich and Au4Ti phases, and Au2TiNi, AuCu and Ni3Ti phases are formed in the brazed joints using Au filler and Au-20Cu filler, respectively. The bending test shows the shape memory effect of brazed joint using Au filler is superior to that using Au-20Cu filler because the detrimental AuCu and Ni3Ti phases exist in the latter case.
