Opis

Bonded magnets are the fastest growing sector in the entire market for magnetic materials. Their great advantages lie in the cost effective net-shape manufacturing process allowing the achievement of complex geometries and their isotropic magnetic properties. Energy products have more than quadrupled in recent years, too. The contributors to this volume present the current and future status of bonded magnets, including total world production and distribution, the markets involved, and the status of current and future applications. Current novel processing techniques are described and new developments reported, including powder production techniques, jet casting/melt spinning, atomization and DDDR processes. The different types of bonded magnets reviewed include isotropic and anisotropic neodymium-iron-boron, nanocomposites, Sm-Fe interstitial nitrides, Sm-Co and ferrites.
