This comprehensive and well-organized text skillfully blends the theoretical and practical aspects of heat treatment. It discusses, in rich detail, about heat treatment of commercial steels, cast irons and non-ferrous metals and alloys. The book also offers an in-depth analysis of topics such as nature of metals and alloys; principles of heat treatment of steels; heat treatment processes; possible defects, causes and remedies in heat treatment; and inspection and quality control in heat treatment. This second edition of the successful text has gone through considerable modification on the basis of responses received. Additional figures have been added for greater clarity and understanding. Multiple choice questions and other pedagogically arranged questions help students to assess their subject knowledge. Designed primarily as a text for undergraduate and postgraduate students of Metallurgy, the book is also useful for undergraduate students of mechanical, production, and chemical engineering. Besides, it meets the requirements of students of AMIE/AMIIM, and of diploma level courses in metallurgical and mechanical engineering. Furthermore, the book can serve as an invaluable reference for practising engineers.

This book deals with earthquake prediction and physical mechanisms of Seismo-electromagnetic (SEM) emissions. SEM emissions are the most promising area of research, to monitor and analyze the effects in the earth and ionosphere that occur several days to few hours before the earthquake. This area of science may very well provide the foundation for earthquake forecasting. This book is aimed to detect the SEM emissions for the earthquake forecasting on ground based and satellites based methods. Especially, ULF emissions are promising candidate for earthquake prediction. This frequency range is easily detected at the earth's surface because of the deeper skin depth effect and low attenuation than that of higher frequency. In this book, analysis of ULF data for spectral density, polarization analysis, fractal analysis and Schumann Resonance Phenomenon, has been shown. This book also contains possible statistical correlation between ionospheric perturbations and earthquakes. Ionospheric perturbations constituted by variations of temperature and density of ionic and electronic components of ionospheric plasma were detected insitu DEMETER and SROSS-C2 satellites.
