“…First, it is preferred that the brazing temperature of Ti does not exceed the a-b transformation temperature (880 C) to preserve the original microstructure and mechanical property of the Ti base metal [2]. In this respect, the previous Ti-based fillers (Ti-Ni-Cu or Ti-Zr-Ni-Cu systems) which provide the superior performance of the joints have shown the shortcoming of their high brazing temperatures usually exceeding 900 C [1,3,4]. The limited solubility of Ti with other elements from a molten filler also induces the undesirable formation of brittle intermetallic compounds such as Ti x Cu y and Ti x Ni y in the joint [1,5].…”

“…According to the main alloying elements, filler alloys for brazing titanium and its alloys can mainly be classified into five groups: titanium-based [1,14,16,[18][19][20][21], zirconiumbased [16,19,22,23], silver-based [24][25][26][27], aluminum-based [28][29][30][31], and nickel-based [19,32] filler alloys. Attempts of brazing titanium using Al-based filler alloys and other filler systems started over than 60 years ago [33].…”

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.

“…The clad Ti-Cu-Ni filler foils provide an alternative approach to braze Ti alloys [14]. Both Ti-15Cu-25Ni and Ti-15Cu-15Ni in wt% have been successfully applied to braze g-Ti 50 Al 50 and Ti-6Al-4V, but shear strength of these joints is below 300 MPa [15]. The stable interfacial a 2 -Ti 3 Al layer in between g-Ti 50 Al 50 and Ti-6Al-4V substrates limits the bonding strength of the infrared brazed joint.…”

“…The stable interfacial a 2 -Ti 3 Al layer in between g-Ti 50 Al 50 and Ti-6Al-4V substrates limits the bonding strength of the infrared brazed joint. Infrared vacuum brazing has been proven to be a useful way for investigating the microstructural evolution of the brazed joint due to its high heating rate of up to 50 C/s [11,12,15,16]. Both the microstructural evolution and shear strength of a 2 -Ti 3 Al and Ti6Al-4V joints infrared brazed using Ti-15Cu-25Ni and Ti-15Cu-15Ni braze alloys were investigated in this study.…”
