Abstract The dealloying mechanism of material in service was discussed on the basis of analyzing the structural morphologies of aluminum bronze tube used in sea water pipe line system.The microstructure and morphologies of aluminum bronze before and after being corroded were examined by optical microscope and SEM.The compositions of corroded aresa were analyzed by EDS and the phases before and after cossosion were determined by XRD.The results revealed that dealuminizationcorrosio was obseived in aluminum bronze tube, and the phenomenon preferentially occurred at the interface of α-phase and metastable β-phase.This set up a path for the selective attack to follow β-phase matrix and eventually penetrated the tube.The α-phase showed a minor tendency to dealiminize.
