  • Materials for extreme environments can help to protect people, structures and the planet. Extreme temperatures in aeroplane engines, hypervelocity micrometeoroid impacts on satellites, high-speed machining of ceramics and strong radiation doses in nuclear reactors are just some examples of extreme conditions that materials need to withstand. In this Viewpoint, experts working on materials for different types of extreme environments discuss the most exciting advances, opportunities and bottlenecks in their fields.
