As we know from theoretical research, titanium (Ti), if it naturally crystallized in the bcc structure, would be a very good superconductor. However, it is not possible to stabilize it in this form under normal pressure and temperature conditions, which significantly limits its practical application.

In the new work published in Acta Materialia, researchers from our institute: dr Piotr Sobota, mgr Bartosz Rusin, dr Rafał Topolnicki, dr Tomasz Ossowski, mgr Wojciech Nowak, and dr hab. Rafał Idczak, prof. UWr in collaboration with the Institute of Low Temperature and Structure Research PAS proposed a solution to this problem by using the high entropy effect.

As a result of appropriate doping of titanium with other metals it was possible to stabilize the bcc phase in two superconductive alloys. High parameters of the upper critical field of the obtained materials indicate that it is a promising direction of development of high entropy superconductive materials.
