Abstract
Co-Si films deposited by coevaporation on silica substrates were melted with a scanned cw argon laser beam. A dramatic phase segregation is exhibited for compositions close to the eutectic composition. The observed morphology is an excellent example of lamellar eutectic solidification and is unusual for these high entropy of melting phases. The lamellae follow the temperature gradient produced by the scanned laser beam and delineate this gradient.Keywords
