Abstract In the frame of the common research project, the mechanical behaviour of recycled thin sheet Ti-Al based
composites reinforced with scrap pure aluminium (AA1050) and boron, B reinforcement elements have been used with
thin Ti-Al sheet recycled by hot forging method. The effects of chemical bonds during the production of these multifunctional
sandwich composite structures were analyzed by 3-point bending tests to evaluated hyper elasticity behaviour. The same idea
has been carried out this time on the Ti-Al based composites performed by sintered + forging through the powder metallurgy
route by using different reinforcements such as TiB 2 , TiC, and B 4 C. Quasi static compression and low velocity impact (drop
weight) tests have been performed on the sintered + forging specimens with a drop tower to observe the response of theses
composites under the dynamic loading conditions. Interface and microstructure of these composites have been evaluated by
Scanning Electron Microscope (SEM).
10.1 Introduction
The new design of composite materials for aeronautical and aerospace engineering such as gas turbine engines, turbo
compressors, etc. need to find a suitable solution between matrix and ceramic reinforcements. The main difficulty of the
actual materials for this application is their high density even if they have high oxidation and creep resistance. For this reason,
new type of intermetallics based composites basically, Ti-Al intermetallic based composites reinforced with fine ceramic
particles can be a future and good candidates due to their low density and stability at high temperature applications up to
700 and 900
C. One of these composites is based on the γ-TiAl intermetallics that presently is used for the manufacturing of
the turbine blades, turbocharger wheels, etc. [1–5]. However, brittleness behaviour at certain conditions of these composites
should be improved by special heat treatments and/or with fine ceramic powders. They do not lose their mechanical
performance against high temperatures in working conditions [6–9]. As a different applications, the use of Ti-Al based
composites in sandwich form reinforced with other compounds can be designed for many useful industrial applications. Thus,
they perform satisfactorily against versatile high stresses occurring on the structure. As an alternative composite design in the
frame of the present research project, pure aluminium, AA1050 and Boron were used as the efficient reinforcing element for
the design of Ti-Al based sandwich structure with different metallic components together in many industrial applications
[1, 10]. Within the scope of this study, AA1050 and ceramic boron, B reinforcement elements have been used with thin Ti-Al
sheet recycled by hot forging method. The effects of chemical bonds during the production of this multifunctional sandwich
