AI-Driven Discoveries of a Novel Form Memory Alloy With Unprecedented Performace

Artificial intelligence discovered a new shape memory alloy

Researchers at Texas A&M University’s Department of Materials Science and Engineering used AIMS (Artificial Intelligence Materials Selection Framework) to find a new alloy with shape memory. The shape memory alloy showed the highest efficiency during operation achieved thus far for nickel-titanium-based materials. Their data-driven framework also offers proof of concepts for future material development.

The Acta Materialia Journal published this study recently.

Shape memory alloys can be used in many fields to replace hydraulic and pneumatic actuators. They deform at cold temperatures and return to their original form when heated. This property is crucial for applications such as aircraft wings, jet engines, and automotive components that require repeated, large-scale shape changes.
