Abstract | The present invention relates to a method for manufacturing a metal plate formed with particles having {100} planes parallel to a plate surface of the metal plate containing a Co alloy of Fe 10-35 wt%. The present invention provides a method for forming a {100} plane texture of the surface of the metal plate, comprising the steps of: heat-treating the metal plate below the temperature for preventing oxidation of a metal surface in a Co alloy group of Fe 10-35 wt% and stabilizing austenite phase temperature; and phase-transforming the heat-treated metal plate to a ferrite phase. In addition, a soft magnetic steel sheet manufactured by the method is provided. The method is able to remarkably reinforce the strength of the {100} plane texture of the Co alloy plate of Fe 10-35 wt% in a short period of time.
La présente invention concerne un procédé de fabrication d'une plaque de métal pourvue de particules ayant des plans {100} parallèles à une surface de la plaque de métal contenant un alliage de Co comportant de 10 à 35 % en poids de Fe. La présente invention concerne également un procédé de formation d'une texture de plans {100} de la surface de la plaque de métal. Un tel procédé comprend les étapes consistant à : traiter thermiquement la plaque de métal au-dessous de la température de prévention d'une oxydation d'une surface de métal dans un groupe d'alliage de Co comportant de 10 à 35 % en poids de Fe, puis stabiliser la température de la phase d'austénite ; et transformer en phase la plaque de métal traitée thermiquement jusqu'à obtenir une phase de ferrite. La présente invention concerne en outre une tôle d'acier magnétique doux fabriquée selon le procédé. Le procédé permet d'accroître considérablement et rapidement la résistance de la texture de plans {100} de la plaque en un alliage de Co comportant de 10 à 35 % en poids de Fe. |
