Concept explainers

Solidification of metals

The term solidification indicates the conversion of material from the state of liquid to the state of solid. The solid-state is more compact and rigid than liquid, and the solidification indicates the transformation of material from a random state to a more compact and crystalline form. The point at which dendrite formation in liquid starts taking place is referred to as the solidification point.
