Hot tearing is a severe defect formed on the surface of castings, ingot, bloom, billet and slab during the solidification of metals and alloys. It often causes expansive cost to fix or direct rejection to these casting products. Its formation process and mechanism, such as where and how it nucleates, and how it propagates after nucleation, is still unclear, although experimental and modelling works have been intensively carried out in this hot research area for many decades. Herein, we carefully carried out a experiment by systematic investigation into the effects of processing variables and casting environment on the defect formation during strip casting steel, and found out its nucleation and propagation process by symmetrically examining into the macro- and micro-structures of the defect.
