Combustion Synthesis of MAX Phase Solid Solution Ti₃(Al,Sn)C₂

Abstract:

Formation of the Ti₃(Al,Sn)C₂ solid solutions was studied by combustion synthesis from elemental powder compacts with Al₄C₃ and TiC additions. Combustion temperatures of 1590–1700 °C and flame-front speeds of 14.2–18.8 mm/s were measured for the Al₄C₃-added samples. Due to the dilution effect of TiC, the combustion temperature and flame velocity were significantly reduced to 1220–1280 °C and 7.1–9.6 mm/s, respectively, for the TiC-adopted samples. The XRD analysis indicated that MAX solid solutions Ti₃(Al₁_–_xSn_x)C₂ with x = 0.2, 0.4, and 0.6 were produced from the Al₄C₃-adopted samples. Because of the low reaction temperature, the extent of Sn substitution for Al in Ti₃(Al₁_–_ySn_y)C₂ was narrowed down to y = 0.4 for the TiC-containing samples. The as-synthesized Ti₃(Al,Sn)C₂ grains were plate-like and closely stacked into a laminated microstructure.
