Abstract

In this paper, three-step heat treatment was developed and performed on 8vol.%TiC/Ti-5.8Al-2Zr-1.3Mo-1V composite prepared by in situ casting route. This heat treatment leads to significant changes in microstructure and tensile properties. Matrix microstructure was refined obviously and fine TiC particles with average diameter of 3.6 μm were obtained. The tensile strength and elongation are all improved at room temperature and 600 °C and room-temperature elongation increases to 5.86%.
