“…The authors determined that titanium diboride particles increase the hardness of the composite versus pure alloy from 455 HV to 555 HV. Walunj G. et al [ 12 ] have shown that in Ni-10 wt % TiC composites fabricated by mechanical alloying of a powder mixture of nickel and titanium carbide with subsequent plasma sintering, nickel matrix grain size decreased from 55 nm to 40 nm as compared to pure nickel. High hardness (350 HV) and compressive strength (1510 MPa) were also recorded.…”

This article considers issues pertinent to the research of the phase composition, structure and mechanical properties of materials obtained from powders of composite (Ni-Ti)-TiB2, which have prospective applications in aerospace and automotive industry and engine construction. The starting powder materials (Ni-Ti)-TiB2 were obtained by self-propagating high-temperature synthesis (SHS). Research samples were produced using high-temperature vacuum sintering. It was shown that the use of such materials increases the wettability of the particles and allows the production of composites, the density of which is 95% of the theoretical one. Average particle size was 1.54 µm, average microhardness was 8 GPa, which is an order of magnitude higher than the average microhardness of pure nickel-based and titanium-based alloys, and the ultimate strength values were comparable to those of tungsten-based heavy alloys.
