Definitions

  • An alloying additive for adding an alloying metal can be employed to add an aUoying metal such as zirconium, manganese, copper, vanadium, iron or chromium, for example, to an aluminium-based melt. When produced by the method of the invention their rate of dissolution may be enhanced.
  • Preferred compositions for such aUoying additives are:
  • zirconium-aluminium comprising zirconium in the range from 5 to 30 weight % , preferably about 15 weight % ;
  • the present invention also comprehends a method of making an aUoying addition to an aluminium melt, comprising adding to the melt a dosage form which has been produced by a method in accordance with the invention.

Abstract

On produit un additif d'alliage à structure métallurgique fine en utilisant une fusion d'un matériau d'alliage approprié, tel qu'une fusion à base d'aluminium contenant un ou plusieurs constituants d'alliage permettant de traiter une fusion à base d'aluminium pour effectuer le recuit d'affinage, la modification, la réduction de conductivité et/ou l'addition du métal d'alliage, et en appliquant un ou plusieurs courants pratiquement non atomisés de la fusion à une surface de refroidissement telle que la surface externe cylindrique d'un tambour métallique rotatif refroidi à l'eau, afin d'obtenir un produit pulvérisé sur disque rotatif qui est alors agencé sous une forme dosée convenant à la préparation d'éléments d'addition d'alliage mesurés, lesquels ont été de préférence initialement granulés.
