Researchers Develop 3D-Printed Shape Memory Alloy with Superior Superelasticity: 3D Printing Leads to Fabricating a Shape Memory Alloy with Increased Superelasticity
Researchers from Texas A&M University recently showcased superior tensile superelasticity by fabricating a shape memory alloy through laser powder bed fusion, nearly doubling the maximum superelasticity reported in literature for 3D printing. Nickel-titanium shape memory alloys have various applications due to their ability to return to their original shape upon heating or upon removal of the applied stress. Therefore, they can be used in biomedical and aerospace fields for stents, implants, surgical devices and aircraft wings. However, developing and properly fabricating these materials requires extensive research to characterize functional properties and examine the microstructure. "Shape memory alloys are smart materials that can remember their high-temperature shapes," said Dr.
