Mark Miodownik puts the properties of a superalloy to the test. Superalloys are high-performance alloys designed to withstand incredible temperatures and pressures. Mark describes how the matrix of cubic crystals in their unique micro-structure makes them super strong, and able to resist the extreme conditions at the heart of a jet engine.

Introduce superalloys, their properties and uses. During the clip, encourage students to take notes on the properties of superalloys and compare these to the properties of pure elements. As well as physical strength and heat resistance, issues related to corrosion could also be discussed. This could form part of student added value research into the uses of alloys compared to metals.
