This handbook gathers, reviews and concisely presents the core principles and varied technology involved in processing alloys of iron with a high proportion of one or more other elements. The work includes detailed coverage of the major technologies of ferrosilicon, ferronickel, ferromolybdenum, ferrotungsten, ferrovanadium, ferromanganese - and numerous lesser known alloys. The most comprehensive currently available book on the topic was probably written by von Durrer and Volkert in 1953 (later re-edited at Springer in 1972). While there have been several publications in Russian including the student handbooks in 1980-2000s (some of them have since been translated into Chinese), a truly comprehensive modern encapsulation of the fundamental science and technology of the field in English is notable for its absence. Distilling the results of 40 years' experience in ferroalloys, Gasik here assembles and tightly marshals lengthy contributions from the worlds' foremost experts. The work is therefore a unique source for specialists, scientists, engineers and university students, exploring in depth an area which is one of the most versatile and increasingly used fields within modern metallurgy, yet least well explored. All-in-one source for the major ferroalloy processes and technologies, cutting research time otherwise spent digging through old handbooks or review articles Encompasses metallurgical procesesses in depth across C, Si, Al-reduction, groups II-VIII of the periodic table Contemporary coverage includes not only process-related but also environment and energy saving issues, and (in the online version) integration with 3D simulations of furnace operations and processes
