摘要

The recent progress of steel manufacturing technology, such as thin slab casting and hot charging has given rise to necessity of refinement of austenite grain size in as-cast steels. One of the benefits of such grain refinement could be the alleviation of hot cracking during steel production. In this work, improvement of hot ductility in the peritectic steel by means of deformation after solidification is studied. Tensile specimens were melted and solidified in situ and the hot ductility was examined at temperatures ranging from 700 to 1100°C, under two conditions: with and without a pre-deformation applied between 1400-1300°C in during cooling. It was noticed that such pre-deformation improves the hot ductility significantly. This improvement could be attributed to austenite dynamic recrystallization and grain refinement taking place during the pre-deformation.
