摘要： A nickel-titanium-rare earth (Ni—Ti-RE) alloy comprises nickel at a concentration of from about 35 at. % to about 65 at. %, a rare earth element at a concentration of from about 1.5 at. % to about 15 at. %, boron at a concentration of up to about 0.1 at. %, with the balance of the alloy being titanium. In addition to enhanced radiopacity compared to binary Ni—Ti alloys and improved workability, the Ni—Ti-RE alloy preferably exhibits superelastic behavior. A method of processing a Ni—Ti-RE alloy includes providing a nickel-titanium-rare earth alloy comprising nickel at a concentration of from about 35 at. % to about 65 at. %, a rare earth element at a concentration of from about 1.5 at. % to about 15 at. %, the balance being titanium; heating the alloy in a homogenization temperature range below a critical temperature; and forming spheroids of a rare earth-rich second phase in the alloy while in the homogenization temperature range.
