摘要

我们提出了一种有效的高速扫描重熔策略，用于改善激光粉末床熔化中 AlSi10Mg 合金的微观结构。优化后的微观结构提高了抗裂纹萌发和扩展的能力，使改进后样品的冲击韧性比普通沉积物提高了 ∼ 76.9%。本研究采用的激光扫描策略提高了铝合金在动态载荷应用场景下的适应性。

Improving impact toughness of aluminum alloy through scanning strategy during laser powder bed fusion

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.
