Le spectre Mössbauer de 119Sn dans l'alliage Al-Cu-Sn est enregistré pendant des recuits isothermes à différentes températures. Les effets des atomes de Sn sur le durcissement structural de l'alliage sont discutés. Il apparaît que l'étain interagit avec les atomes de cuivre pendant le vieillissement à 300 K. Au-dessus de 400 K, il y a formation d'un cluster avec des lacunes et(ou) des atomes de cuivre.The Mössbauer spectrum of 119Sn in the Al-Cu-Sn alloy is measured during isothermal annealing at various temperatures and effects of Sn atoms on the age hardening of the alloy are discussed. It is concluded that tin interacts with Cu atoms during aging at about 300 K. At above 400 K, it forms a cluster with vacancies and/or Cu atoms
