“…[11][12][13] The general formula of MAX phases is M n+1 AX n (n = 1, 2, and 3). M and A denotes an early transition metal and A-group element (mostly III A and IVA, or groups 13 and 14), respectively, and X is C or N. [14][15][16] Accordingly, the most important known MAX phases found by researchers are 211, 312, and 413 types. 17,18 Type 211 is the most investigated MAX phase as well as the first found/studied MAX phase.…”

A 2:1:1 MAX phase, V2AlC, composited with Al2O3 is prepared using spark plasma sintering (SPS). To obtain a sample with suitable physical and mechanical properties, an especial current rate regime is carried out for SPS. Different final temperatures of the synthesis (1000, 1200, 1400, and 1500°C) are considered (named S1000, S1200, S1400, and S1500, respectively). Phase analysis, physical and mechanical properties characterizations, and morphology of the samples are performed to determine the quality of the samples. The best characterizations belong to the samples of S1400 and S1500. Bending strengths about 325 and 316 MPa are obtained for the samples of S1400 and S1500, respectively. Regarding the total MAX phases formation and strength, the optimum sample is S1400. However, regarding bulk density, wear resistance, and hardness, S1500 has an advantage over the S1400. The advantages of S1500, as well as its larger grain size, are attributed to the better sintering of Al2O3.

“…MAXphases combine the properties of metal and ceramics that making them promising materials for different structural and functional applications [1]. MAX-phase compounds are nanolaminates with a layered hexagonal structure related to the P63/mmc space group, consisting of transition metals M, elements of IIIA-IVA subgroup and carbon or nitrogen atoms X [2]. There are six types of MAX phases, among which <211>-phases (M2AX), <312>-phases (M3AX2) and <413>-phases (M4AX3) are distinguished.…”

This paper describes the influence of sintering temperature on phase composition and microstructure of paper-derived Ti3AlC2 composites fabricated by spark plasma sintering. The composites were sintered at 100 MPa pressure in the temperature range of 1150-1350 °C. Phase composition and microstructure were analyzed by X-ray diffraction and scanning electron microscopy, respectively. The multiphase structure was observed in the sintered composites consisting of Ti3AlC2, Ti2AlC, TiC and Al2O3 phases. The decomposition of the Ti3AlC2 phase into Ti2AlC and TiC carbide phases was observed with temperature rise. The total content of Ti3AlC2 and Ti2AlC phases was reduced from 84.5 vol.% (1150 °C) to 69.5 vol.% (1350 °C). The density of composites affected by both the content of TiC phase and changes in porosity.

In this study, titanium carbide was obtained by low-temperature pressureless (at pressure less than 1 MPa) sintering of a mixture of elementary titanium and graphite powders in a hot-pressing plant with a preliminary mechanical treatment of the initial mixture. The sintering was carried out at temperatures of 900 and 1000 °C in argon media. As a result, cubic modification (Fm3m) of titanium carbide was obtained. The content of impurities was about 12–13 wt.%
