Polymer bonded magnets are widely being used in many automotive and non-automotive industries. Because of their many advantages such as low weight, resistance to corrosion and ease of machining the demand for bonded magnets is rising sharply .... But, the presently available bonded magnets are limited in their applications at high temperatures due to the low energy product and poor heat resistance properties. Therefore, a need exists to develop bonded magnets with higher energy product that can withstand operating temperatures of at least 180°C and higher. A key issue is the identification of suitable magnetic powders and polymer matrices, which can perform satisfactorily at the desired temperatures. 3, record 2, English, - polybonded%20magnet

Développement de poudres coercitives et anisotropes de type Nd2Fe14B par combinaison d’un procédé de déformation thermomécanique et d’un procédé de décrépitation à l'hydrogène. [...] Actuellement, l'avenir se situe du côté des aimants liés à matrice polymère, qui présentent de nombreux avantages par rapport aux aimants frittés : facilité de mise en forme, résistance mécanique et à la corrosion accrues. L'étude est donc consacrée au forgeage à chaud, à grande vitesse, d’alliages Nd-Fe-B. Par cette technique, un aimant massif Nd-Fe-B est développé à partir d’un matériau brut ne présentant aucune propriété d’aimant initiale. Ces aimants sont utilisés ensuite comme précurseurs de poudres pour aimants liés anisotropes, obtenues par décrépitation à l'hydrogène(brevet laboratoire de Cristallographie, 1990). 1, record 2, French, - aimant%20li%C3%A9%20%C3%A0%20matrice%20polym%C3%A8re

Le matériau de base est une poudre coercitive mélangée avec un polymère. Les aimants sont obtenus par injection, extrusion ou compression. L’avantage essentiel est la possibilité d’obtenir directement des aimants de formes complexes, inaccessibles par frittage ou coulée. Les aimants ferrites liés, utilisés à l’origine comme joints de portes, trouvent aujourd’hui application dans des moteurs, en raison de l’amélioration de leurs propriétés et de la miniaturisation des autres composants constitutifs. Ils sont aussi utilisés pour l’électronique grand public (haut parleurs de walkmans et de téléphones cellulaires). 2, record 2, French, - aimant%20li%C3%A9%20%C3%A0%20matrice%20polym%C3%A8re

Decrepitation. - Some minerals, when laid upon a hot plate, decrepitate, or fly to pieces, through the unequal expansion which overcomes the cohesion of the molecules. Calcite, fluorite, and barite are examples of this. A mineral which decrepitates may be separated from one which does not by decrepitating and sifting; the latter mineral will be found on the sieve, while that which was finely decrepitated will have gone through. 3, record 6, English, - decrepitation

Séparation par décrépitation. Cette méthode tire profit du comportement particulier de certains minéraux à la chaleur. A l'échelle industrielle, ce système est utilisé uniquement pour l'enrichissement de la baryte. Lorsqu'elle est chauffée au-delà d’une certaine température(...) la baryte se brise en particules de petites dimensions, tandis que les autres espèces minéralogiques qui l'accompagnent demeurent intactes. Il suffit de cribler le matériau pour obtenir un concentré ayant la teneur commerciale. 3, record 6, French, - d%C3%A9cr%C3%A9pitation
