abstract = "A 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.",
