GR5 is the main material of titanium alloy materials
When most people talk about titanium, they usually think of titanium as a single product. In fact, this understanding is inaccurate. Titanium is divided into pure titanium and titanium alloy.
GR5 is the main component in titanium alloys. Currently 60% of titanium is mainly GR5. The main component of GR5 is Ti-6Al-4V, which is an (αβ) titanium alloy with good comprehensive mechanical properties.
GR5 titanium alloy belongs to the national standard name, and different countries have different names.
GR5 titanium alloy is an α-β titanium alloy successfully developed in the United States in 1954. It contains 6% α-stabilizing element lv (aluminum) and 4% β-stabilizing element V (vanadium). The nominal composition of GR5 titanium alloy is 6.0 aluminum equivalent, 4.0 vanadium equivalent, and contains 10%-15% beta phase in the annealed state.
The thermal conductivity of GR5 titanium alloy is 1/5 of iron and 1/10 of aluminum. The thermal conductivity of GR5 is l=7.955W/m·K.
The strength sb of GR5 titanium alloy reaches 1.012GPa and the density g is 4.51g/cm3, making the ratio of strength to density sb/g reach 23.5. This value is much higher than the strength-to-density ratio of alloy steel, showing its excellent strength and lightweight properties.
GR5 titanium alloy physical properties:
The world's GR5 (Ti-6Al-4V) alloy semi-finished product output accounts for more than half of the total output of various titanium alloy semi-finished products, and accounts for more than 80% of the total in the aerospace industry. The main semi-finished products of GR5 titanium alloy include bars, forgings, plates, thick plates, profiles and wires.
The main features of GR5 titanium alloy are excellent comprehensive properties and good process performance. GR5 titanium alloy has moderate room temperature strength and high temperature strength, good creep resistance and thermal stability, high fatigue resistance and crack propagation resistance in seawater, and satisfactory fracture toughness and thermal salt resistance. Stress corrosion capability and not too sensitive to thermal stress corrosion. It has a higher hydrogen content than TC2 and TC1 alloys and is suitable for manufacturing various parts working in a wide temperature range of -196~450℃, especially parts designed using the damage tolerance limitation principle. GR5 titanium alloy also has excellent process plasticity and superplasticity, and is suitable for forming using various pressure processing methods, and is suitable for various welding and machining methods.
GR5 titanium alloy application scenarios
