dc.description.abstractA common phenomenon in the dissimilar joints is the presence of 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 and electronic microscopies When the melted aluminium alloy wet 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, considering the silicon as interlayer, reaching the mean value of 3 mu m, i.e., up to five times thinner if compared to joining without silicon during the process.en
