Abstract

The NiTi alloy was remelted by electron beam zone melting. The initial state of the NiTi samples was after swaging. After electron beam floating zone melting the samples were prepared for optical metallographic analysis, scanning electron microscopy analysis and EDX analysis. Next analysis was made to determine the concentration of interstitial elements (C, O, N). The obtained results were compared to NiTi alloys prepared previously by other technologies (centrifugal casting, etc.).

Keywords: NiTi alloy, electron zone melting, NiTi microstructure, Nitinol, SME
