tc4 titanium alloy material parameters

September 25, 2023
Chinese name: TC4 Titanium Alloy;
　　Type: α+β type titanium alloy
　　Tensile strength: σb/MPa≥895;
　　Working temperature: -100～550(℃);
　　Section shrinkage: ψ(%)≥25;
　　Hardness: HRC30 or so;
　　1.TC4 coefficient of thermal expansion:
　　TC4 titanium alloy has excellent corrosion resistance, small density, high specific strength and good toughness and weldability and a series of advantages, in the aerospace, petrochemical, shipbuilding, automotive, pharmaceutical and other sectors have been successfully applied.
　　2.TC4 titanium alloy mechanical properties: specified residual elongation stress σr0.2/MPa ≥ 825, elongation δ5 (%) ≥ 10;
　　3.TC4 titanium alloy density: 4.5 (g/cm3);
　　4.TC4 titanium alloy chemical composition: TC4 containing titanium (Ti) balance, iron (Fe) ≤ 0.30, carbon (C) ≤ 0.10, nitrogen (N) ≤ 0.05, hydrogen (H) ≤ 0.015, oxygen (O) ≤ 0.20, aluminum (Al) 5.5 ~ 6.8, vanadium (V) 3.5 ~ 4.5;
　　5.TC4 titanium alloy bar density: 4.5 (g/cm3) working temperature -100 ~ 550 (℃);
　　6. Chemical composition: TC4 containing titanium (Ti) balance, iron (Fe) ≤ 0.30, carbon (C) ≤ 0.10, nitrogen (N) ≤ 0.05, hydrogen (H) ≤ 0.015, oxygen (O) ≤ 0.20, aluminum (Al) 5.5 ~ 6.8, vanadium (V) 3.5 ~ 4.5;
