Shape Memory Materials Quiz

What is the primary mechanism that allows shape memory materials to change shape?

• Chemical reactions

• Phase transformations

• Electrical currents

• Magnetic fields

Which phase is present in shape memory materials at low temperatures?

• Austenite

• Vapor

• Martensite

• Liquid

How is the memory shape set in shape memory materials?

• By holding the material in the Austenite phase at high temperatures

• By cooling the material rapidly

• By applying a magnetic field

• By stretching the material

What property allows shape memory materials to return to their original shape after being deformed?

• Magnetism

• Electrical conductivity

• Superelasticity

• Thermal expansion

In the context of superelasticity, what happens when stress is applied to a shape memory material?

• It changes to a liquid phase

• It remains in the Austenite phase

• It transforms into the Martensite phase

• It becomes magnetic
