An alloy refers to a type of mixture made up of chemical elements. It contains atleast one metal. Alloys are used widely as construction materials in many industries. The manufacturing technology, the chemical composition, and (micro) structure of the alloy, all influence the functional qualities of these materials. Some of the popular alloys are steel, brass, bronze, and sterling silver. They have a wide range of applications in the making of tools and automobiles. They are also used within the aerospace industry. Research in this field focuses on improving the functional qualities of construction materials in order to lower their weight and boost their safety of usage. Alloying elements are combined with the base metal in order to obtain various desired qualities such as toughness, hardness, and ductility. This book explores all the important aspects of engineering alloys in the present day scenario. It contains a detailed explanation of their structure and properties. Those in search of information to further their knowledge will be greatly assisted by this book.

The Structures of Alloys of Iron: An Elementary Introduction provides an elementary review of some of the factors affecting the structures of alloys of iron, with examples illustrating points of interest. In view of the existence of books dealing with the technology and properties of iron alloys it was decided that the present book should be concerned only with the structures, and not with the properties of the alloys. In connection with steels it was thought best, in the space available, to deal only with those based on iron-carbon alloys. The book begins with chapters on the metal iron, the crystal structures of iron, the diffusion of iron and its alloys, and the intermetallic chemistry of iron. Subsequent chapters deal with the structure of steels, plain carbon steels, the structure of alloy steels, and cast irons. This book is intended for those wanting to make a general survey of the subject before undertaking a detailed study. The reader must understand clearly that much further work will be necessary before he can hope to understand properly even one class of the alloys of industry .
