On completion of this tutorial you should understand:
- how Deformation Twinning and Martensitic Transformations can generate a shape change
- the phenomenon of Superelastic Deformation, which is a reversible Shape Change effected by Martensitic Transformations
- the role of temperature, which affects the driving force for a Martensitic Transformation, and can also influence the ease of slip (dislocation motion)
- the Shape Memory Effect, in which temperature changes are used (in alloys with certain characteristics) to promote reversible Martensitic Transformations and hence to control component shape
