摘要：

Transient　liquid　phase　diffusion　bonding　(TLP-DB)　of　TiNi　shape　memory　alloy　(SMA)　to　stainless　steel　was　performed　with　AgCu　foil　as　interlayer.　The　effect　of　bonding　temperature,　holding　time　and　bonding　pressure　was　also　investigated.　The　results　showed　that　the　maximum　shear　strength　of　the　joint　was　obtained　for　the　specimens　joined　at　860C　for　60　minutes　with　a　specific　pressure　of　0.05　MPa.　Through　scanning　electron　microscopy　(SEM)　and　X-ray　diffractometry　(XRD)　test,　the　element　distribution　and　phase　composition　of　the　joint　welded　under　the　optimum　process　parameters　were　investigated.　It　indicated　that　the　joint　property　was　significantly　influenced　by　the　formation　of　intermetallics　TiNi2,　TiFe　and　Ti3Ni4　etc.
