“…Besides pores, microcracks were also observed in the sample with a high TiC-Al2O3 content. The formation of cracks in the composite system produced by the SHS process can be attributed to the intrinsic stress generated by the mismatch of thermal expansion coefficients between the different phases during cooling [37].…”

Intermetallic-ceramic composites formed by the self-propagation high-temperature synthesis (SHS) process have attracted much interest in research development since they offer low-cost production and mechanical properties that have characteristically high performance. The objective of this work was to study the effect of reactant compositions on the combustion behaviour, microstructure and mechanical properties of the synthesized product of NiAl-TiC-Al2O3 composite. The reaction mechanism of the synthesized products was discussed based on the observations of the combustion reaction and the microstructure characterization. The results provided information on the relationship between the reactant composition, microstructure and the properties of the products of NiAl-TiC-Al2O3 composites formed by the SHS process.

“…Al 2 O 3 ‐TiC composite ceramics are usually produced by hot pressing (HP) sintering method 9 . HP sintering makes the powder in a thermoplastic state due to simultaneous heating and pressing, which facilitates contact diffusion, flow, and mass transfer of particles 10 . However, the main disadvantage of the HP fabrication process is the low productivity, especially in the case of producing larger samples, and most of the process time is spent cooling from the sintering temperature.…”

As a mature powder metallurgy technology, spark plasma sintering (SPS) achieves rapid heating by applying a high-intensity current to the powder, which can efficiently consolidate the powder material and greatly shorten the processing time.…”

In this paper, Al2O3‐TiC ceramic composites with intragranular nano‐ZrO2 were prepared in vacuum by spark plasma sintering (SPS). The effect of ZrO2 particles with different nano‐sizes on the microstructure and mechanical properties of ceramics was studied. The results show that SPS can achieve relative densification of materials without generating new impurity phases. At the same time, the sintering densification temperature of ceramic materials can be reduced by adding ZrO2 (20 nm) particles. Under the action of SPS strong electric field, the nano‐ZrO2 adsorbed on the surface of the matrix particles can enter the interior of matrix grains, and form intragranular nanostructures when the grain boundaries move and the particles merge. The microstructure and mechanical properties of ceramic materials can be improved through the intragranular structure formed by nanoparticles. The main reasons for the increased strength and toughness of ceramic materials are crack deflection, crack bridging and transgranular fracture.

“…At the same time, ceramics are distinguished by their ability to most effectively resist chemical-thermal and adhesion processes occurring on the cutting edge of the tool during processing. A lot of research carried out by scientists from different countries [1][2][3][4][5][6][7][8][9][10][11] indicates the prospects for the development of these types of materials. It should be noted that in a number of works, researchers pay attention to eliminating one of the most important disadvantages of tool ceramics -reduced crack resistance.…”

Abstract. The paper presents the results of the analysis of the structures of materials obtained as a result of hot pressing of mixtures of the ZrO2(m) –Al – С system of various compositions. The nature of the change in the composition and physical and mechanical properties of the obtained materials was established depending on the concentration of aluminum and carbon in the initial mixture, as well as the parameters of hot pressing.
