The composition of the material is Ti-6Al-4V, which belongs to (a + b) titanium alloy and has good comprehensive mechanical and mechanical properties. Bigger than strength. The strength of TC4 sb = 1.012MPa, density g = 4.4 * 103, specific strength sb / g = 23.5, and the specific strength sb / g of alloy steel is less than 18. Titanium alloy has low thermal conductivity.
The thermal conductivity of titanium alloy is 1/5 of iron and 1/10 of aluminum. The thermal conductivity of TC4 is l = 7.955W / m · K.
Coefficient of linear expansion = 7.89 * 10-6 ℃, specific heat = 0.612cal / g · ℃. Titanium alloy has a low modulus of elasticity. The elastic modulus of TC4, E = 110GPa, is about 1/2 of steel, so it is easy to deform during processing of titanium alloy.
