                         brittle compounds in the joining interface region. The brittle 
                         phases can decrease by introduction of interlayers in the joining 
                         interface, such as silicon, that inhibits the formation of A1(3)Ti 
                         and A1Ti(3) phases in joining process between titanium and 
                         aluminium alloys. In the present work, the joinig of titanium and 
                         aluminium alloys have been carried out using a Yb:fiber laser, 
                         considering the prior silicon film deposited on titanium alloy 
                         interface by DC magnetron sputtering. Butt joint conditions were 
                         maintained constant: laser average power, process speed and beam 
                         positioning along the interface joining toward aluminium alloy 
                         (1200 W, 3.0 m/min and 0. 3 mm, respectively). Metallographic 
                         analyses were carried out on the cross-section joint by optical

                         the solid-state titanium alloy, a more restrict compound layer was 
                         formed in the joinig interface EDS line scanning in the joining 
                         interface showed a reduction of compound layer thickness,

                         3 mu m, i.e., up to five times thinner if compared to joining
