In this paper, the effect of the process parameters of the SHS-extrusion method (the delay time before applying pressure, the speed of movement of the press plunger) on the length and quality of extruded cylindrical rods with a diameter of 3 mm, obtained from TiB – 30 wt. % Ti materials, was studied. Their optimal values were determined: the delay time interval was 3–3.5 s, the press plunger speed interval was 40–50 mm/s. Using the results of SEM and XRD, the structural features of the obtained materials were studied, and their texture was determined. The physical and mechanical characteristics of the obtained materials were measured: porosity, hardness, microhardness.

Physical And Mechanical Characteristics

Compact ceramic materials based on the Ti‒B system modified with 5 wt. % of nanosized Si3N4 particles. The results of studies of the structure, phase composition, and physical and mechanical characteristics of the materials obtained are presented. It is shown that the addition of Si3N4 promotes the formation of new phases, in particular, titanium diboride and nitride in the final product. It was found that the introduction of modifying nanosized Si3N4 particles into the initial charge leads to an increase in hardness and microhardness by 15‒20 %, as well as to an increase in crack resistance by 1,5 times in comparison with unmodified samples.
