This module explores the properties of shape memory alloys, commonly called “memory metals”.  These alloys, when made into wires or thin structures, exhibit the shape memory effect: if bent or deformed, the metal will revert to its original shape upon heating. This module explains this effect in terms of the metal’s crystalline structure at the nanoscale. An activity is provided that allows students to manipulate the memory metals directly.
