Ti–Al 3 Ti laminated composites have been fabricated through reactive sintering in vacuum using Ti and Al foils with different initial thicknesses. The aluminum layer is consumed by forming a titanium aluminide intermetallic compound. Thus, the final microstructure consists of alternating layers of intermetallic compound and unreacted Ti metal. Microstructural characterization by scanning electron microscopy (SEM), X-ray diffractometry (XRD) and energy dispersive spectroscopy (EDX) has shown that only the intermetallic Al 3 Ti is formed, which can be rationalized in terms of thermodynamics and kinetics of phase selection, as well as by the diffusion processes occurring in the presence of liquid Al.
