TC4 titanium alloy, Ti-6Al-4V, is the earliest and most widely developed titanium alloy in the world. Its output accounts for more than half of the world's total output of various titanium alloy semi-finished products, and more than 80% in the aerospace industry. Al improves the room temperature strength and thermal strength of the alloy through solid solution strengthening of the α phase, while V improves both the strength and the plasticity. V can also inhibit the formation of α2 superstructure phase and avoid alloy embrittlement during long-term use.
   The main characteristics of TC4 titanium alloy are excellent overall performance and good process characteristics. It also has excellent superplasticity and is suitable for forming with various pressure processing methods and welding in various ways.
   The main semi-finished products of TC4 titanium alloy are bars, forgings, thin plates, thick plates, profiles and wires. This alloy is mainly used in the annealed state, and solid solution aging strengthening can also be used. However, the quenched cross-section does not exceed 25-30mm, and solid solution aging strengthening is not suitable for thick and large workpieces. At present, for different use conditions and process requirements, many Ti-6Al-4V titanium alloy modifications have appeared in various countries. The main difference is the different Al and V content and the lower interstitial element impurity content, as well as the addition of trace amounts. Ru Ti-6Al-4V alloy.
TC4 titanium alloy is mainly used in aerospace to manufacture various beams, bulkheads, slide rails, landing gear beams in aircraft structures, aeroengine fans and compressor disks, blades, aerospace rocket shells, pressure vessels and various Types of fasteners. Using TC4 titanium alloy instead of 30CrMnSiA structural steel can reduce the weight of parts by about 30%.
  TC4 titanium alloy has also been widely used in the civil industry. For example, gas turbine blades in the power industry, ship propellers in the shipbuilding industry, offshore oilfield drilling platforms in marine engineering, various corrosion-resistant pumps in the chemical industry, artificial implants in medicine, various sports equipment, etc.
