The corrosion behavior of high stiffness NiTiCo shape memory alloys was systematically investigated in the present study including straight wires, wire formed stents, and laser cut stents. It was found that the corrosion behavior of NiTiCo alloys is comparable to that of binary NiTi. This is attributed to the small amount of cobalt used in the ternary alloy. Additionally, the corrosion resistan...

Remarks on the existence for the one{dimensional Fr emond model of shape memory alloys Abstract. In this paper we outline a rigorous proof of the existence of solutions to one{dimensional initial{boundary value problems for the general and complete version of the Fr emond thermo{ mechanical model applying to shape memory alloys.

The three-point-bending shape memory properties, microstructure, and magnetic properties of Fe40.95Ni28Co17Al11.5Ta2.5B0.05 (at.%) alloys were investigated. results showed a martensitic transformation in the samples that aged at 700 °C for 6 12 h under applied fields 0.05 7 Tesla. start temperature increased from −113 to −97 as aging times h. Increasing Tesla, temperatures higher temperature. B...

We show that in metamagnetic shape memory alloys exhibiting a magnetostructural first order phase transition the direct transition from ferromagnetic austenite to nonmagnetic martensite is isothermal. In contrast to the direct transformation, the reverse one nonmagnetic martensite–ferromagnetic austenite is athermal, just as are athermal both direct and reverse martensitic transformations in co...
