“…A similar procedure performed for the Ti 3 SiC 2 sample under an 80 MPa pressure increased the relative density up to 95%, but also exhibited a lower density compared pure Ti 3 SiC 2 due to its higher porosity [35]. The addition of aluminum nitride as a dopant during the Ti-Al-N MAX phase formation gave rise its microhardness due to the dispersion, grain refinement, and homogeneous distribution of the components [57]. Direct comparison of the mechanical properties of the MAX phases is impeded by the significant influence of impurities.…”

“…When the content of AlN is 3 wt.% in the initial charge, it reacts with the titanium matrix during the combustion process with the formation of the Ti 2 AlN and Ti 4 AlN 3 MAX phases. AlN, at a 5 wt.%, decomposes during combustion accompanied with the release of titanium nitrides and pure aluminum, as well as the TiB, TiB 2 , and Ti 2 AlN phases [57]. Ceramic nanolaminates of Ti 3 SiC 2 , Ti 3 AlC 2 , and Ti 2 AlN were produced using TiAl and Ti 3 Al under a nitrogen atmosphere.…”

The MAX phases exhibit outstanding combination of strength and ductility which are unique features of both metals and ceramics. The preparation of pure MAX phases has been challenging due to the thermodynamic auspiciousness of intermetallic formation in the ternary systems. This review demonstrates the power of the self-propagating, high-temperature synthesis method, delivers the main findings of the combustion synthesis optimization of the MAX phases, and reveals the influence of the combustion wave on the microstructure features thereof. The possibility of using elements and binary compounds as precursors, oxidizers, and diluents to control the exothermicity was comparatively analyzed from the point of view of the final composition and microstructure in the following systems: Ti-Al-C, Ti-V-Al-C, Cr-V-Al-C, Ti-Cr-Al-C, Ti-Nb-Al-C, Ti-Al-Si-C, Ti-Al-Sn-C, Ti-Al-N, Ti-Al-C-N, Ti-Al-B, Ti-Si-B, Ti-Si-C, Nb-Al-C, Cr-Al-C, Cr-Mn-Al-C, V-Al-C, Cr-V-Al-C, Ta-Al-C, Zr-S-C, Cr-Ga-C, Zr-Al-C, and Mo-Al-C, respectively. The influence of sample preparation (including the processes of preheating, mechanical activation, and microwave heating, sample geometry, porosity, and cold pressing) accompanied with the heating and cooling rates and the ambient gas pressure on the combustion parameters was deduced. The combustion preparation of the MAX phases was then summarized in chronological order. Further improvements of the synthesis conditions, along with recommendations for the products quality and microstructure control were given. The comparison of the mechanical properties of the MAX phases prepared by different approaches was illustrated wherever relevant.

Compact ceramic electrode materials based on the Ti‒B‒Fe system modified with nanosized particles of aluminum nitride (up to 15 wt. %) were obtained by SHS extrusion. The effect of additives on the combustion characteristics of the studied system, as well as on the structure and phase composition of the obtained materials, is studied. The addition of aluminum nitride increases the content of boride and nitride phases in the final product. It was found that the introduction of modifying nanosized particles of aluminum nitride into the initial charge leads to the grinding of grains of boride and nitride phases, which together increases the microhardness by 10 %, in comparison with unmodified samples.
