Memory Metals
Teaching Materials | 29 Jun 2020 | Contributor(s):: Nano-Link Center for Nanotechnology Education, Matthew Shultz, Deb Newberry, James J Marti
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...

Efficiency of Nitinol Wire
Teaching Materials | 11 Jun 2020 | Contributor(s):: John Nice, NNCI Nano
This lab activity focused on nitinol or muscle wires which are shape memory alloys. These wires can be used to lift a weight up a height. Students will explore how the work performed lifting a load with the nitinol wire compares to the energy pumped into the wire by an electrical current....

Design Challenge: Incorporating Shape Memory Alloys into Rube Goldberg Devices
Teaching Materials | 05 Feb 2020 | Contributor(s):: Joyce Allen, NNCI Nano
This lesson consists of two parts. In Part 1, students determine which of set of wires is a unique metal alloy called Nitinol. Nitinol is called a shape memory alloy (an SMA) because it can “remember” its original shape under certain conditions after being bent, twisted, or...

Shape Memory Alloys: Materials that Remember
Teaching Materials | 28 Jan 2020 | Contributor(s):: Nancy Healy, Gary Harris, NNCI Nano
Students learn about a class of materials called shape memory alloys. In particular, they will explore the properties of nitinol a shpae memory alloy. They will explore how nitinol behaves at different temperatures and what applications these materials are used for.
