Abstract

Ternary MAX phase Ti2SnC was synthesized by Sn-melt infiltration into a porous preform of sub-stoichiometric titanium carbide TiC0.5. Compared to synthesis starting from elemental Ti+C+Sn mixtures which require temperatures exceeding 1100 degrees C a significantly lower reaction temperature as low as 700 degrees C was observed in the TiC0.5+Sn system. This reduction in reaction temperature is rationalized in terms of accumulation of microstrain and decrease of crystallite size upon ball milling of the Ti+C powder mixture. Dense compacts of Ti2SnC with only minor fractions of unreacted TiC0.5 were obtained at 1025 degrees C. Thus reactive solidliquid processing at lower temperatures might be of relevance for MAX phase systems containing low melting A-elements such as Sn, In, Ga, Pb, etc. which tend to become unstable at elevated temperatures.
