What is solidification explain briefly?
Solidification, also known as freezing, is a phase change of matter that results in the production of a solid. Generally, this occurs when the temperature of a liquid is lowered below its freezing point. Solidification is nearly always an exothermic process, meaning heat is released when a liquid changes into a solid.
What are the two stages of solidification of metals?
Mechanism of Solidification of Metals • The solidification of metals occur by nucleation and growth transformation. In nucleation and growth transformation, the nuclei of the solid phase are formed and then they grow.
What is it called when metal solidifies?
Casting is a common metal solidification process which utilized the melting and re-solidification of a metal or alloy within a mold to produce a final desired product. Casting is often used to create complex shapes that would be complicated or expensive to manufacture using other methods.
What are the types of solidification?
The article details five types of solidification undercooling, namely, kinetic, thermal, constitutional (solutal), curvature, and pressure undercooling. It explains the types of nucleation which occur in the melt during solidification.
What is solidification Class 9 Ncert?
The phenomenon of change of liquid to solid is called solidification. For instance, formation of ice from water.
What is the purpose of solidification?
Solidification is the process of transformation of a liquid to a solid. It is the basis of casting technology, and is also an important feature of a number of other processes including welding, surface alloying, crystal growth, ingot production, materials purification and refining.

What causes solidification?
This process takes place in the fusion zone of a weld. It occurs when the supply of liquid weld metal available is not enough to fill the spaces between the solidifying weld metal opened up by shrinkage strains.
What is solidification Class 9 short answer?
What is solidification in manufacturing process?
What are the differences between the solidification of pure metals and metal alloys?
Answer. Pure metals solidify at a single temperature equal to the melting point. Most alloys (exceptions are eutectic alloys) start to solidify at the liquidus and complete solidification occurs at the solidus, where the liquidus is a higher temperature than the solidus.
