Interpretation Introduction
Interpretation:
The characteristics of the microstructure of the cast component needs to be explained.
Concept introduction:
During casting,molten metal is filled in a mold cavity followed by cooling and harden in the desired shape.
There are different stages of forming the structure of metal during casting.
Each stage develops a different characteristic in a microstructure.
