Abstract

Ce produit métallurgique tel que tôle, feuillard, barre, fil, possédant une composition qui le rend difficile à travailler, par exemple un alliage d'acier contenant du bore ou un oxyde réfractaire ou une forte proportion de carbone, est obtenu sous une forme facile à travailler et qui peut être transformée par laminage à chaud ou à froid, étirage, +etc, par le procédé suivant lequel on remplit d'une poudre de la matière difficile à travailler un conteneur formé de la même matière mais dépourvu de l'agent fragilisant (bore, oxyde réfractaire, carbone) on comprime avec une pression suffisante pour établir une liaison métallurgique entre la masse de poudre et la paroi du conteneur puis on travaille l'ensemble obtenu comme une billette. Le produit obtenu comprend un noyau B fait de matière fragile reuni à un placage A fait d'une matière ductile. La réference C désigne l'interfeace.This metallurgical product such as sheet, strip, bar, wire, having a composition which makes it difficult to work, for example a steel alloy containing boron or a refractory oxide or a high proportion of carbon, is obtained in an easy form to be worked and which can be transformed by hot or cold rolling, drawing, etc., by the process according to which a powder of the material difficult to work is filled into a container formed of the same material but devoid of the agent embrittling (boron, refractory oxide, carbon) is compressed with sufficient pressure to establish a metallurgical bond between the mass of powder and the wall of the container then the assembly obtained is worked as a billet. The resulting product comprises a core B made of brittle material joined to a plating A made of ductile material. The reference C designates the Interfeace.
