“…[11][12][13][14] Ti 3 SiC 2 has both metal and ceramic characteristics, its unique lamellar crystal structure gives it high toughness and self-lubrication, but its strength and hardness are low. [15][16][17][18] Ti 3 SiC 2 has low strength (200-400 MPa) and high toughness (more than 7 MPa m 1/2 ) compared with Al 2 O 3 . The thermal expansion coefficient of Al 2 O 3 (7.71 × 10 −6• C −1 ) is similar to Ti 3 SiC 2 (9.1 × 10 −6• C −1 ) so that Ti 3 SiC 2 is a good toughening phase for Al 2 O 3 material.…”

Ti3SiC2/Al2O3 multilayered composites were prepared by the combination of tape casting and hot pressing sintering. The slurry was produced by adjusting the amounts of each organic material, including triethyl phosphate (TEP) as a dispersion, polyvinyl butyrate (PVB) as a binder, dioctyl phthalate (DOP) as a plasticizer, and anhydrous ethanol as an organic solvent. When TEP content was 3 wt.%, PVB content was 4.5 wt.%, R‐value (DOP/PVB) was 1.4, and solid content was 38 wt.%; the cast film with a smooth surface, good flexibility, and uniform thickness was obtained after defoaming, tape casting, and drying. Three samples were prepared, namely, S1–S3. The S1 was monolithic Ti3SiC2/Al2O3 (mass ratio is 1:1) composites. S2 and S3 were Ti3SiC2/Al2O3 multilayered composites, which matrix layers were Ti3SiC2/Al2O3 composites (mass ratio is 1:1) and Al2O3, respectively, and their interface layer was Ti3SiC2. S1–S3 were also sintered at 1550°C. The bending strength of multilayered materials were lower than that of monolithic material, but the fracture toughness of multilayered materials significantly increased. Due to the introduction of Ti3SiC2 interface layer, the friction coefficient and wear rate of Ti3SiC2/Al2O3 multilayered composites were reduced by 30.7% and 33.8%, respectively, compared with monolithic material.

“…The resulting composites showed good mechanical properties, but contained a large amount of TiC impurities. Mishra et al [24] prepared Ti-Si-C series materials with high hardness (22.5 GPa) and elastoplastic deformation through self-propagating sintering with Ti, Si and C as raw materials.

In this study, Ti3SiC2/Al2O3 composites were prepared via in-situ hot pressing sintering at 1550 °C. Al used as a sintering aid reduced the production of TiC impurity phase and stabilized the crystal lattice of Ti3SiC2 to inhibit its decomposiition at high temperature. This is because Al replaced some of the Si atoms to form Ti3(Si1 − xAlx)C2, which showed a crystal structure similar to that of Ti3SiC2. The addition of Al is a prerequisite for the formation of high density Ti3SiC2/Al2O3 composites at high temperature. Laminar Ti3SiC2 grains and granular Al2O3 grains were densely packed and tightly bonded, furthermore, unique mosaic structure of Ti3SiC2-Al2O3 created at high temperatures improve the mechanical properties such as hardness, bending strength and fracture toughness of Ti3SiC2/Al2O3 composites, with the highest reaching 16.97 GPa, 553.38 MPa and 9.63 MPa·m1/2, respectively. The mechanism responsible for improved mechanical properties for Ti3SiC2/Al2O3 composites were the synergistic action of grain pullout, microcrack deflection, and extend the crack growth from two different kinds of grains.

“…The decomposition temperatures of the materials change between 850-2300˚C, depending upon the type and number of impurities present (Li 2003;Bao 2004;Zhen 2005). Preparation and processing methods of MAX phase include solid state synthesis, mechanical alloying (Raoult 1994;Orthner 2002), arc melting (Gupta 2004), hot pressing (Zhou 2000a ), chemical vapour deposition (Zhou 2000b ), spark plasma sintering (Zhou 2000c ), pulse discharge sintering, pressure less sintering (Sun 2002) and selfpropagation (Merzhanov 2004;Mishra 2011). Among the MAX phase ceramics, Ti3SiC2 is one of the most attraction material which is half of the published papers were about it Raoult 1994).…”

There are more than ten MAX phase systems and more than fifty MAX phases. This work is focused to produce Ti3SiC2 MAX phase using Si, C, TiC powders. On the DTA curve of the mixture showed two exothermic peaks at temperature 970 and 1250 ˚C which were related with the formation of the MAX structure on the carbide layer. TiSi, SiC, TiC and Ti3SiC2 phases were detected in the sintered samples at temperature above 1300 ˚C for 3 h sintering time. At higher temperature and longer reaction time, SiC decomposes depending on the holding and reaction temperature. The silicon to titanium carbide and carbon ratios should be in stoichiometric but the silicon content of the starting composition requires more than 20% excess.
