Microstructural characterization of layered ternary Ti2AlC

Structure of a new bulk Ti5Al2C3 MAX phase produced by the topotactic transformation of Ti2AlC

“…Its stacking sequence can be considered as alternate layers of Ti2AlC and Ti3AlC2. This phase has previously been reported by Lin et al in Ti2AlC bulk samples [16] and by Wilhelmsson et al in Ti2AlC thin films [17]. In both cases, however, it was found in samples that were predominately single-phase Ti2AlC.…”

Structural investigation of substoichiometry and solid solution effects in Ti2Al(Cx,N1−x)y compounds

“…One can propose that other considerations should be taken into account to better explain these discrepancies. For instance, some studies show that many stacking faults can exist in Ti 2 AlC [34]. In such a case, values of the lattice parameters conventionally deduced from X-Ray diffractograms can be strongly different from that of a fault-free phase.…”

Effect of Ceramic Content on the Compression Properties of TiB2-Ti2AlC/TiAl Composites

“…However, the strength enhancement of the TiAl matrix composite caused by the addition of TiB2 particles is usually at the cost of plasticity [7][8][9][10]. In contrast to TiB2, Ti2AlC ceramic combines unusual properties of both metals and ceramics, that is it possesses both plasticity and strength [11][12][13]. Although the enhancement effect of Ti2AlC is relatively weaker than that of TiB2, Ti2AlC particles could improve the strength of the TiAl alloy and, at same time, with no great plasticity damage [14].…”
