Abstract

An effective high-speed scanning remelting strategy has been proposed to improve the microstructure of AlSi10Mg alloy in laser powder bed fusion. The optimized microstructures enhance the resistance of crack initiation and propagation, resulting in an increase of ∼76.9 % in the impact toughness of the improved sample compared to the normal deposit. The laser scanning strategy applied in this work promotes the adaptability of aluminum alloy produced via additive manufacturing in dynamic load application scenarios.
