Comparison of the corrosion behavior and surface morphology of NiTi alloy and stainless steels in sodium chloride solution [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2016
The corrosion behavior of NiTi alloy and stainless steels (AISI 316L and X2CrNiMoN22-5-3) in 0.9% sodium chloride (0.154 moll-1) solution was investigated using open circuit potential measurements, potentiodynamic polarization and ...

Preparation of ROS‐Responsive Exosome Coating of Nitinol Material for Making the Neurointerventional Stent

Advanced Materials Interfaces, 2023
Nitinol (NiTi) alloy is an ideal material for preparing neurointerventional stents due to its excellent mechanical properties and biocompatibility. However, NiTi stents without surface‐specific functionalization cause a high rate of stent thrombosis and ...

NEUTRON DIFFRACTION MEASUREMENTS IN EQUIATOMIC NiTi - ALLOYS

Le Journal de Physique Colloques, 1982
Neutron diffraction spectrums of the different phases found in binary NiTi alloys are presented. From these measurements it is possible to separate the influence of precipitates and to differentiate between different proposed models for the martensitic structure. No extra peaks due to the R-phase are observed.

A New Ordered Transformation-Induced Plasticity Enables Exceptional Strength and Ductility in a B2 Medium-Entropy Alloy. [PDF]

Adv Sci (Weinh)
A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior
