Title
(EN) COMPOSITE MATERIAL HAVING IMPROVED MECHANICAL PROPERTIES AT ELEVATED TEMPERATURES
(FR) MATÉRIAU COMPOSITE AYANT DES PROPRIÉTÉS MÉCANIQUES AMÉLIORÉES À DES TEMPÉRATURES ÉLEVÉES
Abstract
(EN)
The present disclosure concerns composite material having improved strength at elevated temperatures. The composite material comprises a matrix of an aluminum alloy (comprising, in weight percent, Si 0.05 - 0.30, Fe 0.04 - 0.6, Mn 0.80 - 1.50, Mg 0.80 -1.50 and the balance being aluminum and unavoidable impurities) as well as particles of a filler material dispersed within the matrix. The matrix can optionally comprise Cu and/or Mo. In some embodiments, the composite material comprises, as a filler material, B4C as well as an additive selected from the group consisting of Ti, Cr, V, Nb, Zr, Sr, Sc and any combination thereof. The present disclosure also provides processes for making such composite materials.

La présente invention concerne un matériau composite ayant une résistance améliorée à des températures élevées. Le matériau composite comprend une matrice constituée d'un alliage d'aluminium (comprenant, en pourcentage en poids, 0,05 à 0,30 % de Si, 0,04 à 0,6 % de Fe, 0,80 à 1,50 % de Mn et 0,80 à 1,50 % de Mg, le reste étant de l'aluminium et des impuretés inévitables) ainsi que des particules d'une matière de charge dispersées dans la matrice. La matrice peut éventuellement comprendre du Cu et/ou du Mo. Dans certains modes de réalisation, le matériau composite comprend, en tant que matière de charge, du B4C ainsi qu'un additif choisi dans le groupe constitué par Ti, Cr, V, Nb, Zr, Sr, Sc et une quelconque association de ces derniers. La présente invention concerne également des procédés pour la fabrication de tels matériaux composites.
