Abstract Scope Composite borides and nitrides are extensively used in several industrial applications as they have extreme corrosion and wear resistance, electrical and thermal properties. The important properties of composite arise due to the existence of the resultant binary and ternary phases namely Ti-N, h-BN, Ti-B-N, etc. The material of interest is the titanium alloy (α+β) with Al and V alloying elements reinforced by Boron Nitride Nanotubes (BNNTs) prepared using Spark Plasma Sintering. In this system, we have explored to understand the evolution of chemical interactions and changes in features during thermal treatment. Detailed X-ray photoelectron spectroscopy (XPS) with imaging/mapping was performed to obtain the reaction phases between BNNT and titanium matrix and resulting morphological features were observed with microscopy. It appears that the nature of any chemical interaction in the system is strongly due to the extent of any physicochemical interactions which occurs at the interface of nanotubes and titanium matrix.
