#ARCTIC. #SIBERIA. THIS IS TAIMYR. Researchers from the Siberian Physics and Technology Institute (SPTI) at Tomsk State University (TSU) have developed a new alloy that has the ability to remember its shape and recover from deformation in the temperature range from minus 70 to plus 100 degrees, the university’s press service reported.
The scientists created three-component single crystals of cobalt, nickel and aluminum CoNiAl. When mechanically impacted, they can change size by 12 percent and completely return to their original state. After heat treatment, the alloy successfully passed cyclic tests, confirming the stability of its properties. According to experts, the alloy will improve the safety of shipbuilding projects, especially in the field of icebreakers for Arctic conditions, TASS writes.
“Our development will help improve various engineering devices, in particular sensors and detectors, or damping structures that reduce the force of vibrations or impacts. The alloy part will allow replacing multi-component complex structures and extending the life of such devices with multiple response cycles, improving their efficiency and increasing their performance, eliminating emergency situations”, explained Anna Eftifeyeva, senior researcher at the laboratory of physics of high-strength crystals at TSU’s SFTI.
