N2 - The study investigates the possibility of controlling the structural and phase state of the titanium matrix composite Ti–6Al–4V–B4C during direct laser deposition. A correlation has been established between the laser processing modes and the microstructure of the composite: variations in energy parameters lead to changes in the concentration of secondary phases (TiB, TiB2, TiC). In this work, synchrotron radiation was utilized for phase analysis, allowing for the determination of the phase composition of the composite through diffraction patterns. It was demonstrated that increasing the laser energy input affects the microhardness of the material, resulting in a 25% increase. The study also evaluates the efficacy of employing additional substrate heating to regulate the extent of dissolution of the initial ceramic particles within the metallic matrix by varying the laser radiation modes. Phase transformation analysis in the titanium matrix composite was performed using X-ray phase analysis with a synchrotron radiation source.
