TC4 alloy contains 6% α- and 4% β-phase stable elemen

Titanium and titanium alloys are widely used in aerospace, automotive, chemical and marine industries due to their low density, high specific strength and good corrosion resistance. TC4 titanium alloy contains 6% α-phase stable element Al and 4% β-phase stable element V, belonging to Ti-Al-V series typical α+β type dual-phase heat-strength titanium alloy, with good mechanical properties and process properties. It can be processed into semi-finished products such as bars, profiles, plates, and forgings, and is increasingly favored by people.

At present, the domestic focus is mainly on the high-temperature properties, creep properties and thermal stability properties of TC4 titanium alloys. The heat treatment process of TC4 TITANIUM ALLOY PLATE is carried out to study the influence of the heat treatment process on the microstructure and mechanical properties of materials. The TC4 titanium alloy rod was prepared by reversal and remelting, rolled into a titanium plate, and subjected to a stress relief annealing treatment at 650 °C for 4 h. The stress-annealed sheet is processed into a microstructure observation sample and a tensile sample and subjected to different heat treatments: annealing, solution hardening, solid solution aging, and furnace cooling.
