“…However, research has shown that the alloys' overall properties depend on the degree of impurity they contained, which adversely affects their plasticity [ 23 , 24 , 25 ]. Titanium alloys undergo plastic deformation when hydrogen, carbon, oxygen, and nitrogen are present [ 26 , 27 ]. In general, alloying elements play a crucial role in stabilizing its α or β phase [ 28 , 29 ].…”

“…The new expectation in modern industries for the machining of materials subject to demanding conditions is related to the high precision, high speed, and high quality of the tool materials used. The cutting tools that operate in severe, and especially under intermittent, cutting conditions must have high hard and wear resistance [ 19 ]. One widely used consolidation of alumina-zirconia matrix composites reinforced with titanium carbonitride is pressureless sintering.…”

Ti(C,N)-reinforced alumina-zirconia composites with different ratios of C to N in titanium carbonitride solid solutions, such as Ti(C0.3,N0.7) (C:N = 30:70) and Ti(C0.5,N0.5) (C:N = 50:50), were tested to improve their mechanical properties. Spark plasma sintering (SPS) with temperatures ranging from 1600 °C to 1675 °C and pressureless sintering (PS) with a higher temperature of 1720 °C were used to compare results. The following mechanical and physical properties were determined: Vickers hardness, Young’s modulus, apparent density, wear resistance, and fracture toughness. A composite with the addition of Ti(C0.5,N0.5)n nanopowder exhibited the highest Vickers hardness of over 19.0 GPa, and its fracture toughness was at 5.0 Mpa·m1/2. A composite with the Ti(C0.3,N0.7) phase was found to have lower values of Vickers hardness (by about 10%), friction coefficient, and specific wear rate of disc (Wsd) compared to the composite with the addition of Ti(C0.5,N0.5). The Vickers hardness values slightly decreased (from 5% to 10%) with increasing sintering temperature. The mechanical properties of the samples sintered using PS were lower than those of the samples that were spark plasma sintered. This research on alumina–zirconia composites with different ratios of C to N in titanium carbonitride solid solution Ti(C,N), sintered using an unconventional SPS method, reveals the effect of C/N ratios on improving mechanical properties of tested composites. X-ray analysis of the phase composition and an observation of the microstructure was carried out.
