AI Technical Summary

Technical Problem

In Ti60 titanium alloy, various elements are difficult to melt synchronously and be evenly distributed within a limited melting time, resulting in elemental segregation.

Method used

The smelting method combines an electron beam cold hearth furnace and a vacuum consumable arc furnace. By determining a reasonable range of alloy element ratios and utilizing the high energy density and refining capabilities of the electron beam cold hearth furnace, the alloy elements are initially homogenized. Then, the composition and structure are further adjusted using a vacuum consumable arc furnace to ensure the uniform distribution of elements.

Benefits of technology

The simultaneous melting and uniform distribution of elements in Ti60 titanium alloy within a limited melting time were achieved, which improved the compositional uniformity and purity, suppressed elemental segregation, and enhanced material properties.

Abstract

This invention discloses a method for preparing Ti60 high-temperature titanium alloy ingots, relating to the field of titanium alloy technology. Based on the target composition range of the Ti60 high-temperature titanium alloy ingot, the proportions of each alloying element in the ingot are determined as follows: Al: 5.8-7.2%, Sn: 3.2-4.3%; Zr: 2.7-3.8%; Mo: 0.3-0.9%; Si: 0.3-0.5%; Nb: 0.3-0.6%; Ta: 0.8-1.4%; C: 0.05-0.07%. By determining a reasonable proportion range for each alloying element, the various elements of the Ti60 titanium alloy achieve synchronous melting and uniform distribution within a limited melting time, suppressing elemental segregation and improving the compositional uniformity of the Ti60 titanium alloy. Furthermore, by first utilizing the high energy density and excellent refining capabilities of the electron beam cold hearth furnace, and then further adjusting the composition and structure through a vacuum consumable arc furnace, the compositional uniformity and purity of Ti60 high-temperature titanium alloy ingots are effectively improved, expanding the application of titanium alloy materials in petrochemical, aerospace, nuclear power generation, hydrogen storage, and military industries.
