Synthesis of high-purity polycrystalline MAX phases in Ti–Al–C system through Mechanically Activated Self-propagating High-temperature Synthesis

Synthesis of Ti2AlC by laser-induced self-propagating high-temperature sintering

“…Using new additive of Sn, higher purity Ti 2 AlC was obtained. Compared to previous work without containing additive [2][3][4][5], Ti 2 AlC content in the sample was increased by about 10%.…”

“…Among this family, Ti 2 AlC is one of the most interesting materials, which has been widely studied in the Ti-Al-C system. For synthesizing Ti 2 AlC, combustion synthesis, self-propagating high-temperature sintering (SHS) [2][3][4][5], hot pressing (HP) [6], hot isostatic pressing (HIP) [7], spark plasma sintering [8] have been used. With shorter reaction period and less energy consumption, SHS has great potential of volume production in industry.…”

Cr2AlC MAX phase as bond coat for thermal barrier coatings: Processing, testing under thermal gradient loading, and future challenges

“…In that way, a new processing route named Molten Salt Shielded Synthesis (MS3) might be an alternative since it leads to synthesis of MAX phase powders in air and without any milling step . Nevertheless, other common processing routes such as solid state reaction (SSR) or self‐propagating high temperature synthesis (SHS) should be also optimized to produce powders with the desired features . Control of the powder features is also rather important, in particular for the deposition process by thermal spray technologies.…”

Macro-porous Ti2AlC MAX-phase ceramics by the foam replication method

“…$ 3 Â 10 6 Ω À 1 m À 1 [10], high thermal conductivity, good thermal shock resistance, machinability and they exhibit a degree of plasticity at elevated temperatures. Their ceramic properties include a refractory nature and oxidation resistance and they can maintain their strength at high temperatures [11] with a decomposition temperature of 1500 1C under vacuum [12]. Sun and Zhou [13] reported a detailed review of the Ti-Al-C MAX-phase system and Ti 2 AlC and Ti 3 AlC 2 are the two aluminium containing MAX-phases of interest due to their low density of 4.1 g/cm 3 [13] along with high oxidation resistance.…”
