Description
Aimant permanent et procédé de fabrication de cet aimant. Le brevet principal a pour objet un aimant permanent, caractérisé en ce qu'il est formé au moins en partie d'un alliage contenant du fer, comme composante prin cipale, de 7 à 40% de nickel et de 3 à 20 d'aluminium. Ce brevet comprend également un procédé de fabrication de cet aimant, ca ractérisé en ce que l'on fait ce dernier, au moins en partie, en un alliage de la compo sition indiquée ci-dessus.
On a indiqué dans ce brevet principal que l'alliage dont est fait l'aimant peut con tenir, en plus des composantes mentionnées, du cobalt en quantité comprise entre 0,5 et 40%. On a trouvé qu'un aimant permanent, possédant des valeurs élevées de magnétisme résiduel, peut être établi à l'aide d'un alliage qui contient du fer comme composante prin cipale, 7 à 40% de nickel, 3 à 20% d'alu minium, 0,5 à 40 % de cobalt et du tungstène en quantité inférieure à<B>10%.</B>
La présente invention comprend donc un aimant permanent formé de cet alliage et un procédé de fabrication de cet aimant.
L'aimant permanent selon l'invention pré sente en général, vis-à-vis de certains aimants décrits dans le brevet principal, une réma nence moindre mais une force coercitive bien plus élevée, de sorte que le produit formé de la force coercitive et de la rémanence, et qui influence les propriétés magnétiques, est au moins aussi élevé ou plus grand que pour les aimants permanents décrits au brevet principal.
Le tableau suivant donne, ù titre d'exem ple, la composition chimique et les propriétés magnétiques d'un aimant permanent -selon l'invention (chiffre 1) et, sous chiffre 2, pour permettre une comparaison, celles d'un ai mant permanent sans tungstène. Les pro priétés magnétiques données :dans le tableau ont- été déterminées au moyen de baguettes cylindriques de 7 mm de diamètre, qui ont été coulées dans un moule et chauffées à l'incan descence à<B>730'</B> C pendant environ une heure.

Cette température, pour chaque cas isolé, dépend de l'épaisseur de la pièce de fonte et de la vitesse avec laquelle cette pièce s'est refroidie dans le moule.
Des propriétés magnétiques élevées peu vent aussi être obtenues en chauffant préala blement les pièces de fonte à une température située au-dessus de 1000 C, mais au-dessous du point de fusion de l'alliage magnétique, puis en les refroidissant subitement et ensuite en les chauffant, pour les recuire, à une tem pérature comprise entre 600 et 800 C.
L'aimant selon l'invention peut contenir, outre les composantes mentionnées ci-dessus, de petites quantités d'un ou de plusieurs des métaux suivants: molybdène, manganèse, va radium, chrome, silicium, argent, étain, cui vre, uranium, béryllium et zirconium.
L'aimant permanent selon l'invention peut en outre contenir de petites quantités de carbone et d'impuretés. La teneur en carbone sera dans tous ces cas inférieure à 1,5 %.
Permanent magnet and method of manufacturing this magnet. The main patent relates to a permanent magnet, characterized in that it is formed at least in part of an alloy containing iron, as the main component, from 7 to 40% nickel and 3 to 20% aluminum. . This patent also includes a method of manufacturing this magnet, ca ractérisé in that the latter is made, at least in part, in an alloy of the composition indicated above.
It was indicated in this main patent that the alloy of which the magnet is made may contain, in addition to the components mentioned, cobalt in an amount of between 0.5 and 40%. It has been found that a permanent magnet, possessing high values of residual magnetism, can be established using an alloy which contains iron as the main component, 7 to 40% nickel, 3 to 20% iron. aluminum, 0.5 to 40% cobalt and tungsten in an amount less than <B> 10%. </B>
The present invention therefore comprises a permanent magnet formed from this alloy and a method of manufacturing this magnet.
The permanent magnet according to the invention has in general, vis-à-vis certain magnets described in the main patent, a lower remanence but a much higher coercive force, so that the product formed by the coercive force and of remanence, and which influences the magnetic properties, is at least as high or greater than for the permanent magnets described in the main patent.
The following table gives, by way of example, the chemical composition and the magnetic properties of a permanent magnet - according to the invention (number 1) and, under number 2, to allow a comparison, those of a magnet. permanent without tungsten. The magnetic properties given: in the table were determined by means of cylindrical rods of 7 mm in diameter, which were poured into a mold and heated incandescent to <B> 730 '</B> C for Approximatly one hour.

This temperature, for each isolated case, depends on the thickness of the cast iron part and the speed with which this part has cooled in the mold.
High magnetic properties can also be obtained by preheating the castings to a temperature above 1000 C, but below the melting point of the magnetic alloy, then cooling them suddenly and then heating them. heating them to anneal them at a temperature of between 600 and 800 C.
The magnet according to the invention may contain, in addition to the components mentioned above, small amounts of one or more of the following metals: molybdenum, manganese, radium, chromium, silicon, silver, tin, copper, uranium , beryllium and zirconium.
The permanent magnet according to the invention can also contain small amounts of carbon and impurities. The carbon content will in all these cases be less than 1.5%.
