Abstract
Studied were the features of formation of brazed joints on titanium aluminide, produced by radiation heating in vacuum using brazing filler metals based on the Ti-Zr system and alloyed with other elements. It is noted that utilisation of copper and nickel containing filler metals does not allow producing a homogeneous structure of metal of the brazed seams. Alloying the Ti-Zr system with iron, manganese and other elements provides structure and properties of the brazed seams close to those of the base material.
