Heat Treatment

Learning Objectives

While reading and after studying this chapter, you will be able to:

● Understand the metallurgical reactions that occur in heat treatment.

● Study and have a knowledge of the vari- ous heat treatments-annealing, normalising, hardening, tempering-which may be given to steels.

● Understand how these range of heat treatments affect the structure and properties of the material.

● Understand T-T-T and C-C-T diagrams and show how non-equilibrium phases can be formed in steel structures. 

● Define and measure the hardness and utilize hardenability curves for predicting hardness values of selected steel products.

● Relate the steel-heating processes with various case hardening processes such as carburising, nitriding, cyaniding, carbonitriding, flame and induction hardening.
