The microstructure of dense TiC/Ti-Cu composites fabricated by pressureless infiltration of TiCu alloy into porous starch derived carbon preforrn produced by 3D-printing has been studied. The reactive melt infiltration was carried out at 1100 degreesC in a flowing Ar atmosphere and resulted in formation of a composite comprised predominantly of substoichiometric TiCx (x=0.78), binary intermetallic Ti-Cu phases and residual carbon. SEM analyses revealed a microstructure consisting of a dispersed fine-grained TiC0.78 (similar to7 mum) in a Ti-Cu matrix. (C) 2004 Elsevier B.V. All rights reserved.
