Phase Transformations

8.1 INTRODUCTION

A metal with desirable mechanical properties can be developed with the help of phase transformation, i.e. controlling the microstructure of the metal with the help of controlled rate of cooling during the phase transformation. The mechanical properties of a metal very much depend upon the grain size refinement, solid solution strengthening and strain hardening. For example, by phase transformation of 0.8 wt% C steel, the strength of this steel can be modified from 600 to 2000 MPa.

Many a times, the rate of cooling is more than the rate of phase transformation, causing delay in transformation and metastable states are formed, because equilibrium microstructures are seldom developed due to this delay. ...
