“…The results indicate that a ternary Al 5 Si 12 Ti 7 IMC phase formed at the Al alloy filler metal/Ti6Al4V brazed with the Al 8.4 Si 20 Cu 10 Ge 0.1 Re filler metal interface. Nesterov et al 107 investigated Ti brazed with an Al brazing alloy joint formation considering wetting the surface and brittle intermetallic interlayer formation. To control the wetting process, it is desirable to reduce the partial pressure of oxygen in brazing.…”

The dissimilar material joining of aluminum and titanium alloys is recognized as a challenge due to the significant differences in the physical, chemical, and metallurgical properties of these alloys, where the increasing demands for high strength and lightweight alloys in aerospace, defense, and automotive industries. Joining these two alloys using the conventional fusion techniques produces commercially unacceptable sound joints due to irregular, complex weld pool shapes, cracking and low strength, high residual stresses, cracks, and microporosity, and the brittle intermetallic compounds formation leads to poor formability or inferior mechanical properties. The formation of intermetallic compounds is inevitable but it is less severe in solid-state than in the fusion welding process. Hence, this article reviews on aluminum–titanium joining using different solid-state and hybrid joining processes with emphasis on the effect of process parameters of the different processes on the weld microstructure, mechanical properties along with the type of intermetallic compounds and defects formed at the weld interface. Among the various solid-state welding processes for aluminum–titanium joining, the following grades of aluminum and titanium alloys were employed such as cp Ti, Ti6Al4V, cp Al, AA1xxx, AA 2xxx, AA5xxx, AA6xxx, AA7xxx, out of which Ti6Al4V and AA6xxx alloys are the most common combination.

“…Many Al-based filler alloys have been developed since that time, and many attempts were made in pursuit of achieving suitable brazing conditions. Titanium was brazed to itself and to aluminum alloys by Al-based fillers using an oxyacetylene torch with flux [30,33], in high-purity argon [10,33], in vacuum [28][29][30][31][34][35][36], and in air conditions: in fluxless process assisted by the ultrasonic vibration (USV) [37][38][39] or by additional pressure [40]. Investigating and improving the mechanical properties of the produced joint through a careful design of the brazing cycle and controlling the intermetallic compound formation/diffusion zone were among the primary explored objectives in brazing titanium and its alloys.…”

Brazing of titanium using low melting temperature filler alloys is a preferred choice regarding cost and preserving its mechanical properties. However, brazing titanium at low temperature is still a challenge, especially regarding aluminum-based filler alloys. During the last years, several brazing methods and Al-based fillers were developed to meet industrial requirements; some of them might achieve some of those requirements. e use of ultrasound in brazing has gained increased attention recently, which helps to reduce the time and the necessity for a special brazing environment, subsequently, reducing cost and increasing applicability. Brazing titanium below the α↔β transformation temperature, using commercial and experimental Al-based fillers of different compositions, is presented in this review; including the procedures of traditional and ultrasound-assisted brazing methods. Correspondingly, the effects of brazing conditions and alloying elements on the mechanical properties and the intermetallic compounds formation are examined.
