A high-toughness homogeneous titanium alloy tee joint pipe and an isothermal forging preparation method thereof

Abstract

The present application relates to the technical field of titanium alloy precision forging, and particularly relates to a high-strength and high-toughness homogeneous titanium alloy tee pipe and an isothermal forging preparation method thereof, the present application is prepared by customization alloy component design, and the synergistic effect of corrosion resistance strengthening of Cr and precipitation strengthening of Si is mainly utilized; a step-by-step process of high-temperature cogging-isothermal forming-low-temperature aging heat treatment is adopted, a special isothermal forging device is configured in the isothermal forming stage, and the precision forming and structure regulation of the tee pipe are realized. The prepared titanium alloy tee pipe has excellent room temperature / high temperature mechanical properties, corrosion resistance and structure stability, has high forming precision, and is free of defects such as cracks and segregation, is suitable for high-temperature and high-pressure fluid conveying scenes in fields such as petrochemical industry, aerospace, nuclear power and the like, and the process is suitable for industrialized mass production.
