Structural and Textural Evolution during Cold Work in Ti-Rich Ni-Ti Shape Memory Alloy
The properties and cost have made the Nickel-Titanium (NiTi) shape memory alloys (SMA) attractive for a variety of applications wherein shape memory effect (SME) / superelasticity (SE) and biocompatibility are important. Anisotropy of the shape recovery associated with shape memory effect strongly depends on the type of r 30 minutes in air) Ti-Rich Ni-Ti SMA (Ni51at%Ti) when subjected to cold r...
متن کاملeffects of mechanical alloying on microstructure and microhardness of nanocrystalline ni–50at.% ti shape memory alloy’
in this work, nanostructured niti shape memory alloy with equal atomic percentage was produced through mechanical alloying. the result exhibited that after 60 h of mechanical alloying of high purity elemental powder mixtures of nickel and titanium by a planetary high-energy ball mill, the ti dissolved into ni lattice and niti (b2) phase with was obtained. the xrd investigations, sem observation...
متن کاملAnodic Fabrication of Ti-Ni-O Nanotube Arrays on Shape Memory Alloy
Surface modification with oxide nanostructures is one of the efficient ways to improve physical or biomedical properties of shape memory alloys. This work reports a fabrication of highly ordered Ti-Ni-O nanotube arrays on Ti-Ni alloy substrates through pulse anodization in glycerol-based electrolytes. The effects of anodization parameters and the annealing process on the microstructures and sur...
متن کاملPerformance evaluation of soft body impact on Ni-Ti shape memory alloy with conical model
The response of soft body impact on a Ni-Ti shape memory alloy with conical model is investigated by using the nonlinear finite element analysis method for obtaining Kinetic Energy, Internal Energy and contact force plot by considering idealized bird model with constant velocity.
متن کاملEffect of Aging on Martensitic Transformation in Ti-Rich Ti–Pd Shape Memory Alloy
Effect of aging on successive martensitic transformation in a Ti–47 at%Pd shape memory alloy has been studied by means of differential scanning calorimetry (DSC) and transmission electron microscopy (TEM). After short time aging successive transformation takes place in Ti–47 at%Pd alloy irrespective of aging temperature. On the other hand, after relatively prolonged period only the specimen age...
