A revolutionary nickel-titanium alloy is set to transform aviation by enabling aircraft wings to dynamically change shape during flight, optimizing their aerodynamics in real-time. This development, spearheaded by Xiaobing Ren and his team at the National Institute for Materials Science in Japan, introduces a new class of materials that combine the strength of steel with extraordinary flexibility. Unlike rigid structures, these materials allow for morphing surfaces, opening new possibilities for aircraft performance, fuel efficiency, and flight control.
