The effect of the thermal treatment on the stress-corrosion of nickel-titanium wires

Abstract

The aim of this research was to analyze the stress-corrosion behavior of NiTi wires used for stent-graft implants. It can be seen from the results that during transformation phase the raw specimens indicate a drastic OCP falloff.
