Abstract

L'invention se rapporte au domaine du traitement des métaux par pression, et concerne notamment des procédés combinés de traitement de métaux en feuille, et plus particulièrement un procédé de fabrication d'ébauches métalliques et composites à partir de matériaux en feuilles qui peuvent être utilisées en génie mécanique. Ce procédé de fabrication d'ébauches métalliques et composites à partir de matériaux en feuilles consiste à enrouler simultanément sur un mandrin au moins deux feuilles de matériaux ayant différentes propriétés de résistance (la tension en étirement d'un des matériaux est plus importante que la limite d'élasticité de l'autre) et à fixer les extrémités du matériau. L'invention se caractérise en ce que l'on enroule des matériaux en feuille bobinés sur des rouleaux en étirant le matériau en feuille ayant les plus hautes propriétés de résistance de 10-60% par rapport à la limite de résistance du matériau à enrouler et en étirant le matériau en feuille ayant les plus basses propriétés de résistance de 0-33% par rapport à la limite de résistance du matériau à enrouler, après quoi on procède à la soudure des couches enroulées. Le résultat technique de la présente invention consiste en une plus grande densité d'enroulement, en la production d'ébauches ayant une composition chimique plus uniforme et une distribution plus égale des propriétés physiques et mécaniques dans leur section, et en un élargissement du domaine d'application.
