Ti5Al2C3, crystal structure, layered carbides, transmission electron microscopy (TEM)
Crystal structure of Ti5Al2C3 was determined by means of X-ray powder diffraction (XRPD), transmission electron microscopy (TEM) and ab initio calculations. In contrast to the already known P63/mmc space group that the MAX phases crystallize, it was demonstrated that the R3¯m space group could better satisfy the experimental data. The lattice parameters are a = 0.305 64 nm, c = 4.818 46 nm in a hexagonal unit cell.
