Abstract

This study focuses on an attempt to improve the oxidation resistance of titanium matrix composites (TMCs) by tailoring an in situ TiC particles reinforced Ti6Al4V (TiCp/Ti64) composites with a novel three-dimensional (3D) network microstructure. The oxidation behavior of the novel composite was investigated in air, between a temperature range of 873-1073 K for 100 h. Oxidation kinetics and microstructural observation reveal that the novel composite exhibits a superior oxidation resistance due to the 3D network microstructure and a self-assembled TiCp wall. The networked microstructure not only effectively blocks oxygen diffusion but also decreases growth and spallation of the oxidation scales. (C) 2012 Elsevier Ltd. All rights reserved.
