Abstract

This paper presents a comparative study of the microstructures formed in Al.59Ge.41and Al.70Ge.30 (eutectic composition) free standing films under laser irradiation. An hexagonal metastable phase located between Allamella, can be formed depending on the film composition and the laser pulse length.
