(a)
Interpretation:
The quenching temperature of steel needs to be determined.
Concept Introduction:
Martensitic transformation is the transformation which a diffusionless reaction and takes place in a military manner. The Trans takes place due to the movement of the atom and the atom changes their position in a coordinated way. Martensite is formed in carbon steel by quenching. The martensite reaction begins during cooling and parent martensite becomes unstable.Ferrite is a ceramic compound formed by mixing and firing a large portion of iron oxide with a small portion of additional metallic element.
(b)
Interpretation:
The carbon content of the steel needs to be determined.
