The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Extractive Metallurgy of Molybdenum provides an up-to-date, comprehensive account of the extraction and process metallurgy fields of molybdenum. The book covers the history of metallurgy of molybdenum from its beginnings to the present day. Topics discussed include molybdenum properties and applications, pyrometallurgy of molybdenum, hydrometallurgy of molybdenum, electrometallurgy of molybdenum, and a survey of molybdenum resources and processing. The book will be a useful reference for metallurgists, materials scientists, researchers, and students. It will also be an indispensable guide for world producers, processors, and traders of molybdenum.

The book marks the Platinum Jubilee of the Indian Institute of Metals, closely matching independent India's age. It is envisaged as a compilation of technical articles tracing the birth and growth trajectory of metallurgical science, engineering and technology in the nation, attempting a degree of prognostication covering the next quarter of a century. It contains the essence of the metallurgical research and development and industrial progress India has witnessed in the last 75 years. This book comprises technical articles written by industry leaders and eminent technocrats. It includes overviews by distinguished researchers who have strived to build foundations of new metallurgical research and engineering fields. It includes learned writings of persons associated with premier institutions heavily dependent on metallurgy and materials. They have made seminal contributions by nurturing the growth of metallurgical research and industrial production or have made first-hand contributions to building the great organisations we have today. Coinciding with the Platinum Jubilee year of the Indian Institute of Metals, this book brings out the enormous efforts of these individuals representing their organisations to share insights that led to their success as an entity. Similarly, several professionals who significantly contributed to the understanding of metallurgical engineering, have held important positions and steered the national strategic programmes or academically nurtured students in their illustrious careers also share their journey in this book. This book chronicles the significant advances made in the field of metallurgical science, engineering and technology in India, presenting the historical perspective and prospects in the format of a technical volume.

The attractive physical and mechanical properties of ordered intermetallic alloys have been recognized since early in this century. However, periodic attempts to develop intermetallics for structural applications were unsuc cessful, due in major part to the twin handicaps of inadequate low-temper ature ductility or toughness, together with poor elevated-temperature creep strength. The discovery, in 1979, by Aoki and Izumi in Japan that small additions of boron caused a dramatic improvement in the ductility of Ni3Al was a major factor in launching a new wave of fundamental and applied research on intermetallics. Another important factor was the issuance in 1984 of a National Materials Advisory Board reported entitled "Structural Uses for Ductile Ordered Alloys," which identified numerous potential defense-related applications and proposed the launching of a coordinated development program to gather engineering property and processing data. A substantial research effort on titanium aluminides was already underway at the Air Force Materials Laboratory at Wright Patterson Air Force Base in Ohio and, with Air Force support, at several industrial and university laboratories. Smaller programs also were under way at Oak Ridge National Laboratory, under Department of Energy sponsorship. These research efforts were soon augmented in the United States by funding from Department of Defense agencies such as Office of Naval Research and Air Force Office of Scientific Research, and by the National Science Foundation.
