Resumo: A partial isothermal section (Ti-TiSi2-TiB2 region) of the ternary Ti-Si-B system at 1250 ° C was determined from heat-treated alloys prepared via arc melting. Microstructural characterization has been carried out through scanning electron microscopy (SEM), x-ray diffraction (xRD) and wavelength dispersive spectrometry (WDS). The results have shown the stability of the near stoichiometric Ti6Si2B phase and a negligible solubility of boron in the Ti-silicides as well as of Si in the Ti-borides. The following three-phase equilibria have been observed in the Ti- TiSi2-TiB2 region: Ti ss+TiB+Ti6Si2B, Ti ss+Ti6Si2B+Ti5Si3, Ti5Si3+Ti6Si2B+TiB, Ti5Si3+TiB+Ti3B4, Ti5Si3+Ti3B4+TiB2, Ti5Si3+TiB2+Ti5Si4, Ti5Si4+TiB2+TiSi and TiSi+TiB2+TiSi2.
