PRODUCT DESCRIPTION

Titanium Alloy Crank Titanium , Shimano Titanium Through Hole Dust Cover

Heat Treatment

TC4 titanium alloy heat treatment: mpa, after solid solution strengthening treatment of TC4 material, the strength does not increase much, that is, it reaches 1100MPa, and the strength in the annealed state is generally 900MPa

The composition of titanium alloy TC4 material is Ti-6Al-4V, which belongs to (α+β) type titanium alloy and has good comprehensive mechanical and mechanical properties. Greater than strength. The strength sb=1.012GPa of TC4, the density g=4.51g/cm3, the specific strength sb/g=23.5, while the specific strength sb/g of alloy steel is less than 18. Titanium alloys have low thermal conductivity. The thermal conductivity of titanium alloy is 1/5 of that of iron and 1/10 of that of aluminum, and the thermal conductivity of TC4 is l=7.955W/m·K.

Linear expansion coefficient=8.6*10-6°C (0-100°C), specific heat=0.612j/g·°C. Titanium alloys have a low modulus of elasticity. The elastic modulus E=110GPa of TC4 is about 1/2 of that of steel, so it is easy to deform when titanium alloy is processed. Its Poisson's ratio is 0.34. TC4 (Ti-6Al-4V) and TA7 (Ti-5Al-2.5Sn) titanium alloys, using two implantation schemes for surface modification, the test shows that after ion implantation of titanium alloys, the microhardness is improved and significantly reduced The sliding friction coefficient was improved, and the wear resistance was effectively improved. In order to prove the modification mechanism, X-ray photoelectron spectroscopy (XPS) analysis was carried out on the injected and uninjected samples, and satisfactory results were obtained.
