The SEM micrographs illustrated in Fig a

7(a) and (b) represent the microstructures of as-synthesized products from TiC- and Al4C3-added samples, respectively. Fig. 7(a) reveals that most of the Ti2(Al,Sn)C DAPTinhibitor are closely stacked into a laminated configuration. The layered microstructure and lamellar grains are typical of the MAX ternary compound. In addition to plate-like grains of Ti2(Al,Sn)C, Fig. 7(b) displays a number of small Ti6Sn5 particles distributed over the fracture surface.
