Abstract: This paper presents a comparative study of the efficacy of fibrous and particulate reinforcement in titanium-matrix composites under high-speed mechanical loading. The structural and phase composition of the synthesized materials is investigated using synchrotron radiation. It is found that, during laser processing, fibrous reinforcing elements dissolve in the titanium matrix to a lesser extent than particulate powder particles. This causes a reduced volume fraction of the resulting secondary phases, such as TiC and Ti$_5$Si$_3$C$_x$ when using SiC fibers, as well as TiB and TiB$_2$ when using boron fibers. It is demonstrated that the use of fibers in the formation of titanium-matrix composite coatings enhances the impact strength of the resulting materials.

Keywords: additive manufacturing, boron fiber, SiC fiber, synchrotron radiation, phase composition, impact strength.
