title = "Degree of undercooling and contact angle of pure iron at 1933 K on Single-crystal Al203, MgO, and MgAI20 4 under argon atmosphere with controlled oxygen partial pressures",
abstract = "Solid or molten oxides are considered to act as nucleation sites during continuous steel casting. The influence of the kind of oxide crystal and atmospheric oxygen partial pressure on the degree of undercooling and contact angle of pure molten iron on oxide substrates was measured by the sessile drop method. On Al203 and MgAI204 substrates, we found that the change in the degree of undercooling was dependent on the existence of a reaction layer and its thickness. On an MgO substrate, since no reaction layer formed, the degree of undercooling was small and was governed by the lattice misfit parameter. The equilibrium contact angle of a molten iron drop on the FeAI204 layer formed between the Al203 substrate and drop was about 100°; a similar contact angle was obtained on MgAI204. The contact angle on MgO changed during observation due to the evaporation of Mg.",
