A rapid method, using woven carbon fiber cloth as carbon supplier, combining with spark plasma sintering (SPS) technique, was proposed to fabricate TiC reinforced Ti6Ai4V based composites. By this way, carburized layer with the thickness of 4 mm can be obtained within 20 min. Microstructure analysis reveals that the composites exhibit advantage of good interfaces between the uniformly distributed TiC precipitates and matrix. Investigations on mechanical properties show that compared with Ti6Al4V matrix alloy, the TiC reinforced Ti6Al4V based composites exhibits higher yield strength, higher ultimate compressive strength, and similar ductility under both quasi-static compression and dynamic compression. The failure mechanisms of the composites and its influence on mechanical properties were discussed. (C) 2014 Elsevier Ltd. All rights reserved.
