Which outcome occurs when molten steel cools below its liquidus temperature during casting?

💡 Explanation

When molten steel cools below the liquidus temperature, solidification initiates with dendritic growth because the solid phase begins to form with a branching structure due to preferential attachment kinetics. Therefore, dendritic growth predominates, rather than eutectic transformation, increased gas solubility, or suppressed nucleation, which have different formation conditions.
