Abstract

Un nouvel alliage métallique à base de cuivre contient principalement du zinc et de l'aluminium en quantités appropriées pour le rendre capable, après traitement thermique en solution à haute température et trempe, de présenter une structure cristalline du type bêta, sa principale caractéristique réside dans le fait qu'il contient simultanément, en tant qu'additifs réducteurs de la dimension du grain, du niobium et du titane en une quantité totale comprise entre 0,01 et 0,2 % en poids.
