First record of shape memory transformation was found in 1932(AuCd)

Shape memory effect was discovered in Nickel-Titanium at the Naval Ordnance Laboratory(NiTiNOL)

Super elasticity

Austenite Martensite

Experiment with NiTiNOL wire to observe it’s behavior

Learn how to train NiTiNOL wire Measure properties and examine

microstructure Design and build devices using NiTiNOL

Designed and shaped our NiTiNOL wire 500° C for 15 min Quenched in water immediately

Polish the NiTinol

Etched our samples

Observed under two different Microscopes

Experimented with NiTinol

springs, rods, and tubes

Used all of the preparation to

build a device.

All NiTiNOL wire Different arrangements

Same length LW on top wire

Same amount of heat applied and same shrinkage

Right angle- medium work

Same diameter MW on bottom wire.
