"Procédé de fabrication d'aimants permanents coulés en alliages du type Fe-Ni-Al".
L'invention est relative à un procédé de fabrication d'aimants permanents coulés en alliages du type Fe-Ni-Al, c'est- à-dire en alliages pour aimants permanents, indiqués par Mishima, dont le constituant principal est le fer et qui contiennent 7 à 40% de nickel et 3 à 20% d'aluminium. L'invention consiste à refroidir rapidement, immédiatement après la coulée, l'alliage liquide fondu. Entre autres manières de procéder, on peut exécuter avantageusement cette opération en coulant à la forme voulue en coquilles métalliques l'alliage fondu.
Quand pour la simplicité on se contente de donner la forme voulue du A
<Desc/Clms Page number 2>
moule à l'évidement du creuset de fusion lui-même - en faisant subir éventuellement un façonnage ultérieur à la pièce coulée dans ce moule - on peut d'une manière appropriée refroidir rapidement le contenu du creuset en arrosant d'eau le creuset ou en soufflant sur lui de l'air froid. Evidemment, dans ce cas, le creuset doit avoir des parois minces et sa conductibi- lité thermique doit être aussi bonne que possible ; étantdonné que dans ces conditions le creuset est exposé à une grande fatigue, ce procédé ne peut être recommandé que pour la fabrication d'un petit nombre de pièces.
REVENDICATIONS ---------------------------
1.- Procédé de fabrication d'aimants permanents coulés en alliages appropriés du type Fe-Ni-A1, caractérisé en ce qu'on refroidit rapidement, immédiatement après la coulée, l'alliage liquide fondu.

"Manufacturing process of permanent magnets cast in alloys of the Fe-Ni-Al type".
The invention relates to a process for manufacturing permanent magnets cast in alloys of the Fe-Ni-Al type, that is to say in alloys for permanent magnets, indicated by Mishima, the main constituent of which is iron and which contain 7 to 40% nickel and 3 to 20% aluminum. The invention consists in rapidly cooling, immediately after casting, the molten liquid alloy. Among other ways of proceeding, this operation can be carried out advantageously by casting the molten alloy to the desired shape in metallic shells.
When for simplicity we are content to give the desired shape of the A
<Desc / Clms Page number 2>
mold in the recess of the melting crucible itself - possibly with subsequent shaping of the casting in this mold - the contents of the crucible can conveniently be cooled rapidly by spraying the crucible with water or by spraying the crucible with water. blowing cold air on him. Obviously, in this case, the crucible should have thin walls and its thermal conductivity should be as good as possible; Since under these conditions the crucible is exposed to great fatigue, this process can only be recommended for the manufacture of a small number of parts.
CLAIMS ---------------------------
1.- A method of manufacturing permanent magnets cast in suitable alloys of the Fe-Ni-A1 type, characterized in that the molten liquid alloy is cooled rapidly immediately after casting.
