Introduction

Ti-Ni alloy, consisting of nickel and titanium alloy in nearly equiatomic proportions, is known for
its unique mechanical properties of shape memory and superelasticity.
These properties occur in association with thermoelastic martensitic transformation.
Superelasticity is a phenomenon at a temperature above the reverse transformation temperature range,
associated with stress-induced martensitic and reverse transformations. The alloy exhibits high flexibility
owing to its wide recoverable strain range, in which the stress is kept low. Since Ti-Ni alloy shows
high corrosion resistance and good biocompatibility, it has been applied in the medical and dental fields.

Fabrication

Cold working

Since the Ti-Ni alloy is an intermetallic compound, cold workability is not good and there are many problems with
using this method of fabrication. In cold working, it is necessary to keep the cold work rate at around 40%
and then soften by annealing. Figure 5.8 shows the work hardening curve.
Because the work hardening rate of Ti-Ni alloy is high, this makes the decrease in workability worse.

Hot processing

The workability of the Ti-Ni alloys is excellent compared with other SMAs, although it is inferior to that of steel;
workability is especially good at high temperatures over 700 °C, where the Ti-Ni alloy becomes more stretchable
due to its reduced strength as shown in Fig. 4.6. However, if excessive titanium is present locally, for example,
due to segregation, a liquid phase appears at temperatures over 950 °C (Murray, 1996) and cracks may form
during processing; thus it is advisable to use a processing temperature of 700 to 950 °C. In particular,
since working speed is relatively fast in hot rolling, attention must be paid to avoid unregulated,
local temperature increases due to the heat of processing.


Applications

NiTi alloy also has good biocompatibility and is compatible with human tissues without causing obvious rejection
or allergic reactions, which makes it safe to be used in the manufacture of various implants and medical devices.
1 At the same time, NiTi alloy also has good corrosion resistance, high strength and lightweight characteristics.
It can exist stably in the body for a long time without being corroded by body fluids or tissues, while providing
sufficient strength while keeping the devices and implants lightweight.

Specifically, the application of NiTi alloy in the medical field includes but is not limited to:

Stents: such as heart stents, vascular stents, etc., used to support narrowed or occluded blood vessels
and restore blood circulation.

Implants: such as orthopedic implants, used to repair or replace damaged bone tissue.

Catheters: used in various minimally invasive interventional and endoscopic surgical devices to help
doctors perform precise treatment.

Occluders: used to block defects or holes in the heart or other blood vessels.
