Modification of microstructure and mechanical property of hypereutectic Al–Si alloy by laser surface remelting

CO2 laser irradiation has been applied to modify the surface of hypereutectic aluminum (Al–23 mass%Si, Al–30 mass%Si) cast alloys. Laser beam, 3 mm in diameter, was irradiated on the alloy surface by moving them with constant velocity (5 mm/s) with beam oscillation of 5 mm in width and 100 Hz in fre...
