Abstract :
Metallic-intermetallic laminate (MIL) composites are promising materials for structural applications
especially in the aerospace industry. One of the interesting laminate composites is the Ti-TiAl3 multilayer. In this work,
commercially pure sheets of aluminum and titanium with almost equal thickness of around 0.5 mm were explosively
joined. The achieved multilayers were annealed at 630 ? in different times so that an intermetallic layer was formed
at the Ti/Al interface. The resulting microstructure was studied by optical and scanning electron microscopy and
Energy Dispersive Spectroscopy (EDS). TiAl3 was the only intermetallic phase that was observed in all annealing
times. The kinetics of the formation of TiAl3 was investigated and compared to previous research studies performed on
Ti-Al multilayers which were fabricated using methods other than explosive welding.
