About the Book

About The Book

The subject and the term "characterization" have become more common during the last few decades, although the main components of the process of characterization, such as mechanical testing, chemical analysis etc., have been in use since the middle of the 19th century. The field of materials characterization brings together all these methods and techniques, for the benefit of scientists, technicians, and experts concerned with quality assurance.

The background of the variety of methods of characterization comes from several fundamental fields, like atomic physics, physical chemistry, mechanics of materials and the science of materials itself as it has evolved over the last several decades. It is necessary that an engineer or technician, trying to understand these methods is given the necessary background information by way of a brief revision so that the application is clearly understood. This has become particularly necessary as there is an extremely large number of different methods in use today, and many of them are quite sophisticated, requiring a good knowledge of the relevant fundamentals.

An Introduction to Material Characterization has been designed with the above particular need in mind. The book summarizes the various methods of characterization of materials commonly used in engineering (metals and alloys, ceramics and polymers). Most books on materials talk about the materials in engineering, their properties, production etc. The techniques of evaluation and characterization are simply mentioned or at the most described briefly. There are very few specialized books on material characterization.

This book helps the reader to gain a good understanding of the principles behind the methods and devices of characterization of materials. These principles are taken from various topics in the basic physical sciences. An engineer dealing with materials needs some help in understanding the background. This also applies to designers, technicians and the selector of materials, who will all benefit from understanding these basic principles.

The books so far published on this topic, generally emphasize only one or two aspects and are not comprehensive in any sense. They mainly deal with their specific subjects within characterization, e.g., microscopy, mechanical testing, chemical analysis etc.

Key features

  • Excellent, relevant science background developed for each field of evaluation of materials.
  • Many diagrams and photographs to make the topic discussed very easy to understand.
  • Diverse topics like compositional analysis and physical methods all combined in one treatise very effectively and usefully.
  • An excellent set of questions and numerical problems at the end of several chapters.
  • Easy presentation, which can be understood by technicians as well as engineer-designers.
