Shape-memory alloys are a class of
Position 1: Such properties have made nickel-titanium alloys invaluable in medical stents and aerospace actuators.
Position 2: This behaviour arises from a reversible phase transformation between two solid crystal structures known as martensite and austenite.
Position 3: Subsequent heating causes the material to revert to its austenitic structure, recovering its original geometry.
Position 4: Shape-memory alloys are a class of materials capable of returning to a predetermined shape after being deformed.
Position 5: When the alloy is cooled, it adopts the more malleable martensitic phase and can be reshaped with relatively little force.
