The difference in the equation for nucleation of a phase in the solid state and equation for the liquid-to-solid transformation needs to be explained. Concept Introduction: By using one or more number of phases, a new phase is formed. This process is known as Phase transformation. This phase transformation occurs when the composition or structure of a material gets changed. This phase transformation occurs at heating or cooling of alloy from its elevated temperature. It does not occur instantly. The phase transformation has 3 subtypes which are: Diffusion dependent phase transformation - In this type of transformation, the composition of alloy is not changed. For example: Melting, recrystallization, solidification. Diffusion dependent phase transformation with change in composition of alloy - In this transformation, the composition of alloy is changed. For example: Eutectoid transformation. No diffusion phase transformation (diffusion less) − For example: Transformation of martensite.

Interpretation Introduction

Interpretation:

The difference in the equation for nucleation of a phase in the solid state and equation for the liquid-to-solid transformation needs to be explained.

Concept Introduction:

By using one or more number of phases, a new phase is formed. This process is known as Phase transformation. This phase transformation occurs when the composition or structure of a material gets changed.

This phase transformation occurs at heating or cooling of alloy from its elevated temperature.

It does not occur instantly.

The phase transformation has 3 subtypes which are:

Diffusion dependent phase transformation - In this type of transformation, the composition of alloy is not changed. For example: Melting, recrystallization, solidification.

Diffusion dependent phase transformation with change in composition of alloy - In this transformation, the composition of alloy is changed. For example: Eutectoid transformation.

No diffusion phase transformation (diffusion less) − For example: Transformation of martensite.
