This book has been carefully written in a simple way to understand the Ductile Iron Metallurgy and Production Process for the Technical Students and for the Practicing Engineers. Metallurgy of Ductile Iron is a vast subject but in this book it has been brought in to a capsule form to understand mainly for the Budding Engineers. Melting Practices of Ductile Iron ,Metallurgical Defects and Remedies for the Defects have been discussed in this book which were derived from the Practical Experiences. In this book the application of Thermal Analysis on Ductile Iron has been discussed. It will give a new insight to Ductile Iron Manufacturers and also to the Research Scholars.
