Abstract

Titanium matrix composites (TMCs) shows great potential in aerospace application. However, hard ceramic reinforcements make the hot working of TMCs challenging. In the present work, large spherical Ti powders were introduced into TiC-reinforced Ti matrix composites to improve the deformability at higher temperatures. This composite showed a flattened network structure after hot extrusion. Plastic deformation of TiC occurred during extrusion. Compared with the composites with homogeneous microstructure, the flattened network structured TiC/Ti composite has higher elastic modulus but lower strength.
