“…However, the addition of Si to Ti 3 AlC 2 can form Ti 3 Al 1-x Si x C 2 (x<=0.25) solid solutions and increase the hardness and strength of Ti 3 AlC 2 [15]. Moreover, preparation of Ti 3 Al 1-x Si x C 2 solid solutions with x=0.2-0.8 was investigated by self-propagating high temperature synthesis using TiC-, SiC-, and Al 4 C 3 -containing powder compacts [16]. To the best of our knowledge, there are no further reports on the properties of Ti 3 Al 1-x Si x C 2 (x=0.2-0.8) solid solutions.…”

The electronic structure and elastic properties of Si doping Ti3Al1-xSixC2 (x=0-1) were studied by generalized gradient approximation (GGA) based on density functional theory (DFT) and virtual crystal approximation (VCA). The calculated lattice parameters and equilibrium volumes are in good agreement with the available experimental data. The density of state (DOS) shows that the DOS at the Fermi level (EF) is located at the bottom of a valley. Single-crystal elastic constants were calculated and the polycrystalline elastic modules were estimated according to Voigt, Reuss and Hill’s approximations (VRH). The results show that the bulk modules increase monotonously and the Poisson ratio v as well as BH and BG increase first and then decrease with the increasing of the doping Si. The Passion ratio v and BH/GH indicate that Ti3Al1-xSixC2 (x=0-1) are brittle compounds. Polycrystalline elastic anisotropy coefficients AB and AG were also derived and are very small.

“…To improve the purity of MAX, Al 4 C 3 has been used to replace Al in starting mixtures because, at sintering temperatures, Al 4 C 3 can provide both Al and C atoms in the system of M–Al–C, and also Al 4 C 3 cannot be easily lost due to its higher melting point (2200°C) than Al. The Al containing MAX phases and their solid solutions such as (Ti 1−x Nb x ) 2 AlC, 13 Ti 3 Si 1−x Al x C 2 , 14 Cr 2 AlC, 15,16 Ti 2 AlC, 17,18 Ti 3 AlC 2 , 19 ZrAl 4 C 4 , 20 Zr 2 Al 4 C 5 and Zr 3 Al 4 C 6 , 21 Nb 2 AlC and (Ti,Nb) 2 AlC 22 have been consequently synthesised.…”

The deleterious effect of Al 4 C 3 on the performance of MAX ceramics has not attracted much attention. In the present study, Al 4 C 3 containing Cr 2 Al(Si)C and SiC/Cr 2 AlC ceramics have been prepared. It was found that spontaneous pulverisation of the as synthesised samples took place at room temperature after exposure in air and water for various durations. Volume expansion induced by the interaction of Al 4 C 3 with moisture is held responsible for the disintegration of Al 4 C 3 containing MAX ceramics. Preventive measures to avoid the formation of Al 4 C 3 upon preparing MAX ceramics were herein proposed.
