The β titanium alloy matrix composite changed into crafted from a combination of elemental steel powders, including boron carbide. During the excessive-temperature sintering process, in situ synthesis came about because of the TiB and TiC reinforcing stages formed. The identification of those stages changed into showed via way of means of X-ray diffraction and microstructural analyses. The presence of unreacted B4C debris and the encircling response layers allowed for the assessment of diffusion kinetics of alloying factors the usage of SEM and EDS analyses. The path of diffusion of the alloying factors withinside the multicomponent titanium alloy and their affect at the in situ synthesis response taking vicinity had been determined. In addition, the connection between the microstructural components, strengthening stages, and hardness changed into also determined. It changed into proven that during situ reinforcement of titanium alloy produced from a combination of elemental powders with complicated chemical composition is feasible below the proposed conditions. Thus, it's been confirmed that sufficiently excessive temperature and good enough conserving time lets in one to recognize the kinetics of the synthesis of the strengthening stages, which were proven to be managed via way of means of the concentrations of alloying factors.
