Liquid Metal Feeding: Quantifying its role on defect formation

轻金属在汽车和运输行业的使用不断增加，通过减轻重量来提高燃料经济性和性能的需求。铸造轻金属产品通过取代黑色金属为基础的部件，如气缸盖和通过零件整合，显示出良好的市场渗透率。虽然轻金属的使用可以提高汽车的能源效率，但需要在制造过程中不断改进，以提高产量和生产能源效率。从历史上看，消除铸造缺陷的策略的发展一直是一个反复试验的过程。然而，计算能力的不断提高导致使用数学模型来改进铸造设计，提供铸造系统的定量知识。

Light metals usage in the automotive and transportation industries continues to increase with the demand for improved fuel economy and performance through weight savings. Cast light metal products have shown good market penetration by replacing ferrous based components such as cylinder heads and through part consolidation. While light metals usage may advance vehicle energy efficiency, continuous improvement is needed in the manufacturing processes to increase yield and production energy efficiency. The development of strategies to eliminate casting defects has historically been a trial and error process. However, the continued increase in computational capabilities has led to the use of mathematical models to improve casting design, providing quantitative knowledge of casting systems.
