Synthesis, Structure and Properties of Ti₃(Si_xAl_1-x)C₂ Solid Solutions

Abstract:

In this paper, we presented a novel route for fabricating Ti3SiC2-based and Ti3AlC2-based solid solutions with mixed powders of TiC/Ti/Si/Al in different molar ratios. The phase compositions of these solid solutions were studied by XRD and the stoichiometries of these compounds were determined to be Ti2.63Si0.87Al0.13C2 and Ti2.76Al0.78Si0.22C2 by EDS. We also investigated the electronic properties and mechanical properties of these two ceramics. The results showed that the dopants were not only beneficial to the fabrication of Ti3SiC2 and Ti3AlC2 but also improved the properties of these two ceramics.
