Structure and functional properties of heat-and thermomechanically treated Ti-Ni-Nb-based alloys with a wide martensitic hysteresis. I. Ti-Ni-Nb ternary alloys

Shape-memory NiTi–Nb foams

“…28) of such alloys used liquid processing approaches, such as arc-or induction-melting followed by casting. Although previous studies of these NiTi-Nb alloys have focused on the shape-memory properties for coupling/joint applications, [29][30][31][32][33] or more recently, on hydrogen dissolution and diffusion in membranes for hydrogen purification, [34][35][36] biomedical implant applications (such as stents 37,38 ) are another promising use for these alloys. In fact, a NiTi-Nb alloy with Ti 44 Ni 47 Nb 9 composition prepared by arc-melting was found to develop passive oxide layers imparting high corrosion resistance when tested in simulate body fluid.…”
