Deux alliages à base titane, Ti46 Al54 et Ti88,8 Cu2,3 Al8,9, ont été étudiés à la sonde atomique. Un précipité de la phase Ti2 Al a été analysé dans l'alliage binaire. La microanalyse de l'alliage Ti Cu Al a révélé la présence de zones enrichies en Cuivre. L'étude a également mis en évidence une pénétration d'Hydrogène dans les échantillons probablement due à la technique de préparation. Les résultats obtenus démontrent la faisabilité d'études d'alliages à base titane à la sonde atomique.Two different titanium base alloys, Ti46 Al54 and Ti88.8 Cu2.3, Al8.9, have been studied by atom probe microanalysis. A precipitate of Ti2 Al was analysed in the binary alloys. Micro-analysis of Ti Cu Al alloy revealed the presence of Copper enriched zones...
