LAMINATED COMPOSITE MATERIALS BASED ON ORTHORHOMBIC ALUMINADE/TITANIUM ALLOY
Résumé
Laminated composite materials consisting of an orthorhombic Ti2AlNb based alloy and an (a+b) titanium alloy have been fabricated at a laboratory scale using a two-step process involving diffusion bonding and hot-pack rolling. The feasibility of fabrication of two- and three-layered materials with high quality bonding between layers has been demonstrated. Preliminary assessment of the tensile mechanical properties of the obtained composite materials at room and elevated temperatures showed that, on the whole, they were superior to those of the titanium alloy and insignificantly inferior to the orthorhombic alloy.
