Ti-Al3Ti laminated composites have been fabricated through reactive sintering in vacuum using Ti and Al foils with differentinitial thicknesses. The aluminum layer is consumed by forming a titanium aluminide intermetallic compound. Thus, the final microstructureconsists of alternating layers of intermetallic compound and unreacted Ti metal. Microstructural characterization by scanningelectron microscopy (SEM), X-ray diffractometry (XRD) and energy dispersive spectroscopy (EDX) has shown that only theintermetallic Al3Ti is formed, which can be rationalized in terms of thermodynamics and kinetics of phase selection, as well as by thediffusion processes occurring in the presence of liquid Al.
