摘要：

Ti2SnC ternary compound was successfully synthesized utilizing laser ignited self-propagating high-temperature synthesis (SHS) of Sn-Ti-C system with the different C/Ti molar ratio. When C/Ti ratio is 0.7, Ti6Sn5 as the main phase appears, and a small amount of TiC is also found, most of the Ti6Sn5 phases synthesized exhibit the polygon-shaped coarse appearance with an obviously sintered morphology, and the distinct transgranular and intergranular microcracks can be observed. When C/Ti ratio increases over the range from 0.8 to 1.0, the relative content of Ti2SnC increase and the plate-like shape Ti2SnC appears. Furthermore, the sintered density increases firstly and then decreases with the increasing of C/Ti ratio. (C) 2011 Elsevier B.V. All rights reserved.
