PROCEDE DE PREPARATION DE MASSES COULEES METAL- LIQUES EXEMPTES DE PORES, EN PARTICULIER D'AL LIAGES RENFERMANT DU MAGNESIUM$PAR INTRODUCTION D'HYDROGENE DANS LE METAL EN FUSION.
L'introduction de l'hydrogène dans le métal en fusion, lors de l'opération d'affinage,est connue,
Mais le pouvoir de l'hydrogène à se oombiner est beau- ooup trop faible pour qu'il puisse réagir aveo la vitesse néoes.' saire.
On a oonstaté, que si à l'hydrogène,on ajoute des hydrures métalliques, par exemple de silicium, de bore, de zirconium ou d'antimoine (SiH4, B4H10, ZrH4, SbH3), le pouvoir de réaction de l'hydrogène est considérablement renforoé.
Grâce au procédé, on peut obtenir les produits de coulée de qualité meilleure, du fait que les matières nooives sont entièrement éliminées,
L'invention s'applique principalement aux alliages ayant approximativement la composition suivante @
<Desc/Clms Page number 2>
1.- 80% de cuivre et 20% de magnésium; 2.- 75% de silicium, 20% de cuivre, et 5% de magnésium; 3.- 505 d'aluminium, 40% de magnésium et 10% de nickel; 4.- 80% de zino, 10% de plomb, 8% de cuivre, 2% de magnésium. etc..
L'examen d'un alliage ayant la composition 92% d'aluminium, 6% de magnésium, 2% de nickel) indique, par le traitement à l'hydrogène ordinaire, une résistance à la trao- tion de 4205 K mm2, tandis que par addition d'hydrure de zirconium, lors du traitement, on obtient une résistance à la traction de 17.28 K mm2.

- REVENDICATION @ Procédé pour la fabrication de masses ou pièces coulées exemptes de pores, en particulier d'alliages renfermant du magnésium par introduction d'hydrogène dansle métal en fusion, caractérise par l'introuduction,en même temps que l'hydrogène, d'un hydrure métallique, tel par exemple un hydrure de sili- cium, de bore, de zirconium ou d'@@timoine (SiH4, B4H10, ZrH4, SbH3).
