Intermetallic compounds of rare-earth and 3d transition metals K I3 J BUSCHQW Philips Research Laboratories, Eindhoven, The Netherlands Abstract A survey is given of the physical properties, composition and crystal structure of intermetallic compounds formed between rare-earth elements and 3d transition elements.

Intermetallic compounds are usually brittle with high melting points. Their properties are often found among ceramic and metallic materials. In most cases, their hot corrosion resistance and simultaneously hardness are important.

One of the main applications of intermetallic compounds is for superalloy turbine blades in which they show appropriate high-temperature-related properties. This book. Recent studies indicate that China accounts for about 96 percent of the world's supply of rare earth materials (REMs).

With REMs becoming increasingly important for a growing number of high-tech applications, appropriate action must be taken to mitigate the effects of a shortage of critical REMs in defense systems and ng together iReviews: Rare earth intermetallic compounds book.

The rare-earth iron magnets are indispensable components in a vast range of electronic and electromechanical devices. This book covers the principles of Reviews: 2. A survey is given of the composition and crystal structure of existing rare earth transition intermetallics.

The relationship in crystal structure of the compounds RM 2, RM 3, R 2 M 7, RM 5, and R 2 M 17 is briefly discussed (R and M represent a rare earth and 3d element, respectively).

The variation of the magnetic moment of the M atoms and the variation of the Curie temperature brought about. The magnetocaloric effect (MCE) in many rare earth (RE) based intermetallic compounds has been extensively investigated during the last two decades, not only due to their potential applications for magnetic refrigeration but also for better understanding of the fundamental problems of the paper reviews our recent progress on studying the magnetic properties and MCE in.

The results obtained in this investigation have been used, together with those of other previously studied rare earth–Zn systems, to predict the constitutional properties of the Tb–Zn and Ho–Zn systems, taking into account that the alloying behaviour of the different rare earths with the same element varies according to systematic patterns.

The dehydrogenation of propanol has been studied in the range – K in the presence of hydride-forming rare-earth intermetallics R 2 Co 7 (R = Pr, Nd and Sm). The use of these hydride-forming compounds is advantageous in the dehydrogenation reaction under mild conditions, since the formation of metal hydrides can change the unfavourable equilibrium in favour of dehydrogenation.

Rare-earth intermetallics own CsCl-type structure with space group Pm3¯m (no). In this type, the rare earth element (Ho) resides on (0,0,0) Wyckoff position and the transi-tion metal atom occupies (,) site of the unit cell [26].
