“…The realization of joining titanium aluminides to other materials opens up the possibility of producing dual property components like compressor and low pressure turbine blisks [ 85 ]. However, the diffusion bonding of titanium aluminides to other materials is more difficult than bonding to themselves.…”

“…The diffusion bonding between titanium aluminides and Ti alloys was systematically investigated in the existing literature [ 67 , 69 , 85 , 87 , 88 ]. According to elemental gradient diffusion at the interface, the preferred reaction phase betwen TiAl intermetallics to TC4 alloys is α 2 -Ti 3 Al phase.…”

Welding and joining of titanium aluminides is the key to making them more attractive in industrial fields. The purpose of this review is to provide a comprehensive overview of recent progress in welding and joining of titanium aluminides, as well as to introduce current research and application. The possible methods available for titanium aluminides involve brazing, diffusion bonding, fusion welding, friction welding and reactive joining. Of the numerous methods, solid-state diffusion bonding and vacuum brazing have been most heavily investigated for producing reliable joints. The current state of understanding and development of every welding and joining method for titanium aluminides is addressed respectively. The focus is on the fundamental understanding of microstructure characteristics and processing–microstructure–property relationships in the welding and joining of titanium aluminides to themselves and to other materials.

“…The use of γ-TiAl alloys as structural materials, will require the development of reliable and cost-effective joining techniques. Diffusion brazing [5] and diffusion bonding [6][7][8] seem to be the most straightforward techniques to produce joints with mechanical properties comparable to those of γ-TiAl alloys at high temperature. Diffusion bonding causes less disruption of the surface of the components to be joined and more homogeneous interfaces than does diffusion brazing.…”

Abstract. Ti-47Al-2Cr-2Nb was joined by diffusion brazing using a Ti-Ni clad-laminated filler alloy. Brazing was performed in the temperature range of 1000 to 1200ºC for 10 min. The microstructure and the chemical composition of the interfaces were studied by scanning electron microscopy (SEM) and by energy dispersive X-ray spectroscopy (EDS), respectively. The reaction between the γ-TiAl alloy and the liquid produced interfaces essentially composed of α 2 -Ti 3 Al and TiNiAl intermetallics. When joints are brazed at 1150 and 1200ºC, the γ-TiAl phase is also detected at the interface.

“…The titanium aluminide alloy is considered to be a potential material for high-temperature structural applications in aerospace and automotive industry. Compared to conventional superalloy, titanium aluminide alloy have several advantages, such as high specific strength, high specific stiffness, good creep and oxidation resistance at elevated temperature [1][2][3][4][5][6].The operating temperature can enhance to more than 900℃, especially when the element of niobium was added into the conventional titanium aluminide alloy. However, low plasticity and low formability at room temperature restrict the extensive application of the high niobium containing titanium aluminide alloy.…”

The solid-state diffusion bonding experiments of the high Nb containing TiAl alloy were successfully carried out at the 1100℃ under a uniaxial pressure of 30MPa for 45min, and the microstructure as well as the shear strength of the diffusion bonding interface with different surface roughness were investigated. The surface roughness was measured by AFM, and the microstructure characterization of interfaces was taken by SEM, EDS, AES. In addition, the bond qualities were evaluated by shear testing at room temperature. The results indicated that the surface roughness is of importance to improve the quality of diffusion bonding joint. Moreover， the white layer microstructure at the bonding interface was found in some samples which was caused by the oxygen content about 2%~3%. Furthermore, the shear teat showed that the shear strength of the joints can achieve 383MPa with the surface roughness is 0.062μm. Meanwhile, the recrystallization phenomenon at the diffusion bonding interface could improve the shear strength.
