Abstract (EN): 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 1200degreesC 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 gamma-TiAl alloy and the liquid produced interfaces essentially composed of alpha(2)-Ti3Al and TiNiAl intermetallics. When joints are brazed at 1150 and 1200degreesC, the gamma-TiAl phase is also detected at the interface.
