Ablation casting is an emerging sand casting technology that achieves high cooling rates in a casting during its solidification, especially its eutectic solidification of the metal, resulting in an extremely fine eutectic microstructure, reduced levels of defect, and enhanced mechanical properties of the casting. The technology is creating extensive interest in the industry for its capability in producing castings with high mechanical properties and internal integrity. However, scientific research lags behind the industrial applications of this new technology. There is a lack of scientific understanding on the solidification features of the castings made using ablation casting. Experimental data on the microstructural length scales seem inconsistent. This article aims at interpreting the experimental data available in the literature by considering the solidification characteristics of ablation casting. The paper also discusses certain research needs to further exploring the potential of the ablation casting process.

烧蚀铸造是一种新兴的砂型铸造技术，可在铸件凝固过程中实现较高的冷却速度，尤其是金属的共晶凝固，从而导致极细的共晶显微组织，降低的缺陷水平和增强的铸件机械性能。该技术以其生产具有高机械性能和内部完整性的铸件的能力引起了业界的广泛兴趣。但是，科学研究落后于这项新技术的工业应用。对于使用消融铸件制造的铸件的凝固特征缺乏科学的了解。在微观结构长度尺度上的实验数据似乎不一致。本文旨在通过考虑消融铸件的凝固特性来解释文献中提供的实验数据。本文还讨论了某些研究需要，以进一步探索消融铸造工艺的潜力。
