Abstract

The relationship between the tensile properties and microstructure of Ti-TiC composite materials with Al additions was investigated. Composites containing 40–50% TiC by volume were produced using standard casting procedures from the melt. Ultimate tensile strengths of 1113 MPa with 1–2 % ductility were found in these materials. Results show that the tensile properties are controlled by the size and distribution of TiC particles.
