Ti-6Al-4V heat treatment performance

      The Ti-6Al-4V titanium alloy is heated to 1020 degrees, and the alloy’s high-temperature microstructure is composed of single-phase β, which is a solid solution. When the microstructures obtained are different at different cooling rates, such as water quenching, air cooling and furnace cooling, the microstructure obtained is different. The water quenching (WQ) structure is martensite α’+β phase, the air cooling (AC) structure is needle-shaped α+β phase and original β grain boundary phase, and the furnace cooling (FC) structure is strip-shaped α+β phase and original β phase grain boundary.

      As in the above case, when heated to 950 degrees and 850 degrees, the microstructure obtained after cooling is also different after different cooling speeds. At 950 degrees, the quenched (WQ) tissue in water is the primary equiaxed α phase and α’+β phase, the air-cooled (AC) tissue is the primary equiaxed α phase and the needle-shaped β phase, and the furnace-cooled (FC) tissue is the primary equiaxed α phase and the grain boundary. At 850 degrees, the quenched (WQ) tissue in water is the primary equiaxed α phase and the metastable β phase, and the air-cooled (AC) tissue is the primary equiaxed α phase and the transformed β phase.

      After heating Ti-6Al-4V titanium alloy to 1020 degrees, 950 degrees and 850 degrees, it cools at different cooling speeds. The room temperature mechanical properties are shown in Table 1
