Abstract

Extended X-ray absorption fine-structure (EXAFS) experiments were performed above the Ti, Ni and Zr K absorption edges in the icosahedral Ti45Zr38Ni17 phase and in its 1/1 approximant, the Ti50Zr35Ni15 phase. The EXAFS spectra show a strong similarity for both samples, indicating that the local structures around the Ti, Ni and Zr atoms are similar in the icosahedral and 1/1 phases.
