The basic physical and chemical properties of titanium aluminide alloys based on intermetallic phases TiAl (γ) as well as their brazeability have been discussed. The principles of the diffusion brazing process and application conditions have been presented. The shear strength and structures of the joints of TiAl48Cr2Nb2 alloy based on the TiAl (γ) phase diffusion brazed with the use of sandwich type silver filler metal (grade B-Ag72Cu-780 and Ag96Cu alloy as a filler metal), copper (grade B-Cu100-1085) interlayers as well as brazing conditions have been given. The structural tests were conducted using light microscopy, scanning electron microscopy (SEM) and energy-dispersion spectrometer (EDS). The results of the shear strength tests were also presented.
