Phase Transformations in Metals and Alloys Third Edition by David A. Porter, Kenneth E. Easterling and Mohamed Y. Sherif



Preface to the Third Edition:

The fundamental theories of phase transformations in metals and alloys remain largely unchanged, so the third edition is essentially an expanded version of the second edition with additional material covering some of the more important application developments of the last 17 years.

A section addressing the computation of phase diagrams has been added to Chapter 1 and recent developments in metallic glasses have been treated in Chapter 4. Chapter 5 contains most new material:

the Scheil method of calculating a CCT diagram from a TTT diagram is now given; the treatment of the nucleation and growth of polygonal ferrite and bainite has been expanded to include new theories, while new case studies cover copper precipitation hardening of very low-carbon bainitic steel and very fine carbide-free bainite were added.

In Chapter 6, a more detailed treatment of stress-assisted and strain-induced martensite is included to provide a theoretical background to transformation-induced plasticity (TRIP) steels.

Preface to the Second Edition:

In the ten years since this book was first published there have been many new developments in the metallurgical field.

Rapidly solidified metals and glasses have come of age; new Al-Li alloys are now used in modern aircraft; microalloyed (structural) and high purity (pipeline) steels have become more sophisticated;


radically new oxide-dispersed steels have appeared; a number of new memory metals have been developed; the list could go on. In spite of this, the underlying principles governing all of these developments have obviously not changed over the years.

This is really the strength of the present text book. From the beginning we aimed to spell out these principles in a nice, readable way, and one in which undergraduates could appreciate and be capable of developing for themselves.

The present text is thus deliberately little changed from the original. We have, however, hopefully corrected any errors, expanded the lists of further reading, and perhaps, most importantly, included a complete set of solutions to exercises.

We hope that the revised edition continues to be enjoyed and appreciated in the many Schools of Metallurgy, Materials Science and Engineering Materials we know to be using our text throughout the world.

In completing this revised edition we are grateful to the many people, students and professors alike, who have written to us over the last decade.

Particular thanks are due to Dr Wen-Bin Li (University of Luleå) for using a fine tooth-comb in bringing out both obvious and less obvious errors in the original text.

There remain, (inevitably), a few ‘points of contention’ concerning our description of certain phenomena, as raised by some of our correspondents, but there is nothing unhealthy about that.

We should finally like to thank Dr John Ion (University of Lappeenranta, Finland) for his help in compiling the Solutions to Exercises chapter.
