Effects of TiC and Al4C3 addition on combustion synthesis of Ti2AlC

Combustion synthesis of Ti2(Al,Sn)C solid solutions from Ti/Al/Sn/C samples with addition of TiC and Al4C3

“…1(a) and (b), both powder compacts were subjected to a considerable axial elongation and a slight radial contraction during the progression of the combustion front. Elongation of the burned sample was often observed in the preparation of MAX ternary carbides by combustion synthesis [25,26]. It was believed that the axial elongation of the burned sample was caused by the growth of plate-like MAX carbide grains into a laminated structure [25][26][27].…”

Microstructure and properties of hot pressed Zr2(Al(Si))4C5/SiC composites

“…Ternary aluminum carbides in the Ti-Al-C system have been successfully synthesized and their high-temperature oxidation resistance and toughness have been substantially improved compared with TiC [3][4][5][6][7]. In comparison to the Ti-Al-C system carbides, ternary Zr-Al-C compounds have been less well studied.…”

Formation of TiAl–Ti2AlC in situ composites by combustion synthesis

“…1(b) reveals that the powder compact is subjected to an axial elongation, which is typical of SHS formation of the ternary carbide Ti 2 AlC. Due to the growth of synthesized carbide grains into a layered structure, elongated products have been commonly obtained from combustion synthesis of various ternary carbides, such as Ti 2 AlC [32], Ti 3 AlC 2 [33], and Ti 3 SiC 2 [34].…”
