摘要

To further explore the various properties of titanium alloys, particularly their high-temperature performance, and to enable their better application in high-temperature environments, a novel composite titanium alloy, TA1/TC4, was developed through the EBF process. This study primarily investigates its tensile properties at both room and elevated temperatures, aiming to explore the material’s high-temperature tensile behavior and the changes in its internal microstructure under different temperature stretching conditions. The results indicate that, compared to its tensile performance at room temperature, the tensile properties of this material significantly decrease at higher temperatures. XRD analysis was conducted to examine the oxidation process at different temperatures. Field-emission scanning electron microscopy revealed that as the temperature increases, the coarse needle-like α phase transforms into a finer α phase, with a notable increase in the β phase content, eventually forming a net-like structure at 550 °C. Through EBSD and microhardness testing, it was found that there are hard-to-detect interfaces within the material, and as the temperature rises, certain diffusion processes occur in different regions.
