Gold is a high-quality hedge hedging tool, favored by investors. Especially in recent years, with the increasing instability of the world economy, gold has become one of the preferred asset allocations of investors because of its functions of hedging and fighting inflation.
Earlier, the worsening situation in Ukraine sent gold prices soaring to a two-year high of $2,070 an ounce. But gold, along with other commodities, fell back last week as conditions changed and bulls took profits, hitting a low of $1,895 an ounce. As of press time, gold was trading at $1,918 an ounce, down 7.9% from its March 8 peak. Rising gold prices may also have an impact on the 3D printing TC4 powder， prices.
According to China Business News, Goldman Sachs raised its gold price forecast in early March, considering Asian buyers' gold consumption demand, investment demand and central bank gold purchase demand continue to rise. Three -, six - and 12-month targets were raised to $2,300, $2,500 and $2,500 an ounce, respectively, from $1,950, $2,050 and $2,150. The last time all three accelerated was in 2010-11 when gold prices rose nearly 70%.
The World Gold Council has also noted that global gold demand is at its highest level in nearly two years, which is linked to a recovery in consumption and consumer sentiment to combat inflation.
The titanium alloy TC4 material composition is Ti-6Al-4V, which belongs to the (α+β) type titanium alloy and has excellent comprehensive mechanical properties. Greater specific strength. The strength of TC4 sb=1.012GPa, the density g=4.51g/cm3, the particular strength sb/g=23.5, and the particular strength sb/g of alloy steel is less than 18. Titanium alloy has low thermal conductivity. The thermal conductivity of the titanium alloy is 1/5 that of iron and 1/10 that of aluminum. The thermal conductivity of TC4 is l=7.955W/m·K.
Coefficient of linear expansion=8.6*10-6℃(0-100℃), specific heat=0.612j/g·℃. The modulu of elasticity of titanium alloy is low. The modulus of elasticity of TC4 is E=110GPa, which is about 1/2 of steel, so it is easy to deform when titanium alloy is processed. Its Poisson's ratio is 0.34. The surface modification of TC4 (Ti-6Al-4V) and TA7 (Ti-5Al-2.5Sn) titanium alloys adopts two implantation schemes. Tests show that after ion implantation of titanium alloys, the microhardness is increased and significantly reduced. The sliding friction coefficient is improved, and the wear resistance is effectively improved. To explore the modification mechanism, X-ray photoelectron spectroscopy (XPS) analysis was performed on the injected and uninjected samples, and satisfactory results were obtained.
TC4 titanium alloy is one of the most widely used titanium alloys. It has high strength and excellent corrosion resistance, but it is challenging to see seamless titanium tubes made of TC4 in the transparent titanium tube market at home and abroad. TC4 titanium material is mainly plate material, and TC4 pipe material on the market is primarily a high-strength thick-walled pipe produced by hot extrusion or oblique perforation.
The main reason for this situation is the high strength of TC4 titanium alloy and the difficulty of cold rolling forming. To solve the critical technology of TC4 seamless tube cold-rolling forming, a series of researches were carried out jointly by schools and enterprises. For example, the direct cold-rolling forming process produces high-strength titanium alloy pipes, which not only dramatically reduce the production cost but also meets the requirements for high-performance titanium alloy applications.
