Densification, characterization and oxidation studies of (TiCr)B2Â +Â 20% MoSi2

► High dense composites (4.81 g/cc) of pre-alloyed (TiCr)B2 + 20% MoSi2 were prepared. ► Moderate hardness in the range of 24-27 GPa was recorded. ► The nature of oxidation changed from parabolic to cubic with increase of CrB2. ► Protective oxide layers of TiO2, Cr2O3 and SiO2 were identified on oxidized surface. ► Formation of a continuous, crack free and protective thick glassy phase was seen.
