Iron played an important role in the development of the industrial society and has not lost any of its significance since today. This book provides the foundations of understanding the physical nature of iron and its alloys. Basics and recent developments concerning its constitution and magnetism are presented as well as its thermal properties. The exceptional role of iron with its wide spectrum of most different technological and physical properties relies on its versatility, its polymorphism of its crystal structure and its magnetism. Therefore it is the aim of the book to link together the constitution and magnetism of iron.

11 Chapter 11 -21 Cast Iron • Ferrous alloys with > 2.1 wt% C – more commonly 3 - 4.5 wt%C • low melting (also brittle) so easiest to cast • Cementite decomposes to ferrite + graphite Magnetic Alloys | Cobalt Institute In contrast, hard magnets have a high coercivity and can be permanently magnetised by applying a magnetic field. Soft Magnets. Cobalt is predominantly used in hard magnets however some soft magnetic cobalt alloys are also in use. These alloys contain cobalt and iron with vanadium added to improve ductility.
