These measurements were performed in the temperature range of 300 K to 700 K with the oscillation frequency about 1.0 Hz. The experimental results showed relaxation peaks due the stress induced ordering of oxygen atom and pairs of oxygen atom around the niobium atoms (metallic matrix) and around titanium atoms (substitutional solute).135-138engArtigo10.1051/jp4:1996827WOS:A1996WM77200028Acesso restrito29499838674183380000-0002-3336-309X
