Product Description

Ni-Ti shape memory alloys are extremely interesting materials both for their ability of showing the shape memory effect (SME) and for their elevated strength and ductility.
A shape memory alloy is a material that undergoes a phase transformation when it experiences a mechanical stress or temperature change. When the conditions return to normal, the SMA "remembers" its original shape and reverts to it.

Shape memory alloys do exactly as their name would suggest; they're metallic materials that are able to remember, and return to, their original shape (the shape they are given when made, say as a casting or an extrusion) under the right stimuli. The principle behind this unusual phenomenon comes from two diverse atom arrangements (crystal structures) present in this material - one at high temperatures and one at low temperatures - that are reversible.
At high temperatures, where one of the crystal structures is favoured, the material can be shaped as desired and it retains this geometry as it cools to lower temperatures. Cooled, the material can be bent and twisted beyond all recognition of its previous guise but, on heating, the low temperature atomic arrangement reverts to its previous form and, in so doing, miraculously returns to its previous shape.
