The hard-magnetic properties of rare earth-transition metal alloys Abstract: The intermetallic phases formed between the rare earth metals R and the elements of the 3-d transition series are a large group of new substances with interesting magnetic properties. They have been studied intensely in the last decade. Their properties are reviewed with a view toward their usefulness for permanent magnets.
Some aspects of the recently developed magnets based on certain RCo 5 compounds are discussed. The prediction is made that second-generation rare earth magnets can be developed using R 2 Co,Fe 17 alloys.
These should have energy products and thermal stability superior even to sintered SmCo 5 , while being less expensive.
Experimental evidence supporting this claim is discussed. Article :. Date of Publication: Sep Need Help?
Magnetic Properties of Metals
They are available chemically combined with other elements. Metals are extracted from there ores. The properties of the metal are defined as the special qualities or characteristics of metals that determine their suitability for a specific engineering application. Although metals have a wide range of properties, the knowledge of the important properties will be helpful in the section of the metals for a specific application. Mechanical properties of metal indicate the nature of its inherent behavior under the action of the external force.
Magnetic Properties of Metals
It seems that you're in Germany. We have a dedicated site for Germany. During the last decades the knowledge of the magnetic properties of the d transition elements and of their metallic alloys and compounds has increased widely. The improvement of preparation techniques for well-defined substances, the development of sophisticated measuring methods and above all the drive to obtain more insight in the origin of magnetic interactions in solids have resulted in the publication of many specific magnetic properties for an abundance of all kinds of metallic materials. It has been attempted to include preferentially those properties which are of a basic character and which therefore are most often needed by scientists active in the field of solid state magnetism.
It should come as no surprise that the properties of extended solids are also connected to their structures, and so to understand what they do we should begin with their crystal structures. Most of the metals in the periodic table have relatively simple structures and so this is a good place to begin.
In metallurgy , a non-ferrous metal is a metal, including alloys , that does not contain iron ferrite in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight e. For example, bauxite is used as flux for blast furnaces , while others such as wolframite , pyrolusite and chromite are used in making ferrous alloys. All pure metals are non-ferrous elements except iron also called ferrite, chemical symbol Fe, from the Latin ferrum , meaning "iron". Important non-ferrous metals include aluminium, copper, lead , nickel , tin , titanium and zinc, and alloys such as brass.

Лицо ее побелело, глаза не отрываясь смотрели на застывший кадр, демонстрировавший неподвижное тело Дэвида Беккера, залитое кровью, брошенное на пол мини-автобуса.
