Properties and Application of 3D Printing Metal Powder TC4
Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal, consultancy Wood Mackenzie said on Monday.
The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.
Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on the 3D printing TC4 powder， prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.
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.
