TC4
Quantity:
TC4 Titanium Alloy
Data grade: TC4 titanium alloy
Product origin: Kobe, Japan/ATI, USA/Taotitanium
1. Overview of TC4 titanium alloy:
TC4 titanium alloy has a series of advantages such as excellent corrosion resistance, small density, high specific strength, good toughness and welding properties.
The composition of the TC4 data of titanium alloy is Ti-6A1-4V, which belongs to (α+β) type titanium alloy, with good comprehensive mechanical and mechanical performance.
Higher strength. The strength of TC4 is sb=1.012GPa, the density g=4.51g/cm3, the specific strength of sb/g=23.5, while the specific strength 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, and the thermal conductivity of TC4 is 1=7.955W/m·K.
Linear expansion coefficient = 8.6*10-6℃ (0-100℃), specific heat = 0.612j/g·℃.
Titanium alloy has a low elastic modulus. The elastic modulus of TC4 is E=110GPa, which is about 1/2 of the steel, so it is easy to deform during processing of titanium alloys. Its Poisson's ratio is 0.34.
TC4 (Ti-6Al-4V) and TA7 (T1-5A1-2.5Sn) titanium alloys were surface modified using two implantation schemes. The experiments showed that after ion implantation, the microhardness of the titanium alloy increased and significantly reduced the The sliding friction coefficient is effectively improved. To explore its modification mechanism, x-ray photoelectron spectroscopy (XPS) analysis was performed on the injected and uninjected samples to obtain satisfactory results.
