AI Technical Summary
Existing high-temperature resistant titanium alloys exhibit decreased tensile strength and elongation after fracture at temperatures of 650°C and above, failing to meet the requirements for high-temperature service. This is mainly due to insufficient high-temperature creep resistance, coarsening of silicides, and uneven microstructure.
By designing Ti-Al-Zr-based titanium alloys and adjusting the mass ratio of Mo to Si to (1.5-2.5):(0.3-0.5), combined with specific forging processes, the microstructure is controlled, and the synergistic effect of Mo and Si is used to strengthen the β phase, regulate the precipitated phase, and improve high-temperature performance.
It achieves high tensile strength and high elongation after fracture at temperatures of 650℃ and above, meeting the requirements for high-temperature service, and improving the uniformity of microstructure and thermal stability.
