Ablation casting is a relatively new casting technique which can improve the mechanical properties of castings. In this paper, the microstructure and mechanical properties of plain carbon steel castings produced by conventional casting and ablation casting techniques were compared. It was found that ablation increased the ultimate strength from 638 to 1094 MPa and tensile elongation increased from approximately 13 to 16% as a result of severe microstructural changes from ferrite and pearlite to acicular ferrite, bainite, and martensite. Ablation increased the core hardness of the casting from 182 to 467 HB and the surface hardness from 205 to 508 HB.

消融铸造是一种相对较新的铸造技术，可以改善铸件的机械性能。本文比较了常规铸造和烧蚀铸造技术生产的普通碳素钢铸件的组织和力学性能。结果发现，由于铁素体和珠光体向针状铁素体，贝氏体和马氏体的剧烈微观结构变化，烧蚀将极限强度从638 MPa增加到了1094 MPa，拉伸伸长率从大约13％增大到16％。烧蚀将铸件的芯部硬度从182 HB增加到467 HB，表面硬度从205 HB增加到508 HB。
