Super-elastic shape-memory material
University of Connecticut researchers discovered a super-elastic shape-memory material that could use as an actuator in the rough conditions, such as outer space. The discovery might be a new class of shape-memory materials.
Generally, the shape-memory materials used in a wide range of consumer products, such as “unbreakable” frames for glasses. Materials with shape-memory properties can return to their original shape by magnetic forces or heat even after significantly natural shape.
Materials science and engineering professor Seok-Woo Lee studied calcium iron arsenide (CaFe2As2), an intermetallic compound. The material commonly used in high-temperature superconductors, extensive research had already examined the compound’s superconducting and magnetic properties.
With the help of previous studies on calcium iron arsenide’s electronic properties, the researchers measure the material’s high degree of pressure and strain sensitivity for potential applications as a structural material.
