IN718: The Most Widely Used Superalloy Material in the Field of Additive Manufacturing
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 IN718 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.
High temperature alloy refers to a type of metal material based on iron,
nickel, and cobalt that can work for a long time at a high temperature above 600
℃ and a certain stress; and has high high temperature strength, good oxidation
and corrosion resistance, Good fatigue performance, fracture toughness and other
comprehensive properties. The superalloy is a single austenitic structure, which
has good structure stability and service reliability at various
Based on the above-mentioned performance characteristics, and the high degree
of alloying of superalloys, it is also called "superalloys". It is an important
material widely used in aviation, aerospace, petroleum, chemical industry, and
ships. According to the matrix elements, high-temperature alloys are divided
into iron-based, nickel-based, cobalt-based and other high-temperature alloys.
The service temperature of iron-based superalloys can generally only reach
750~780℃. For heat-resistant parts used at higher temperatures, nickel-based and
refractory metal-based alloys are used. Nickel-based superalloy occupies a
particularly important position in the entire field of superalloys. It is widely
used to manufacture the hottest parts of aviation jet engines and various
industrial gas turbines.
Features and application fields of IN718
The unique alloy composition design of IN718 makes it have good comprehensive
properties, namely higher strength, creep resistance and fatigue life, good
ductility, excellent oxidation resistance, especially under 650℃, its mechanical
properties Has good stability. Many parts of modern aero-engines, such as
turbine discs, blades, brakes, shafts, stators, seals, supports, pipes,
fasteners, etc., are all made of IN718.
At the same time, IN718 is also used in nuclear reactors (heat exchanger
pipelines), submarines (propeller blades, quick disconnect devices, auxiliary
propulsion motors), chemical industry (containers, pumps, valves, pipelines),
power generation (industrial gas turbines), oil and gas industry ( Downhole
piping, wellhead hardware, flare arm) and other fields have important
Application of IN718 in the field of additive manufacturing
When traditional manufacturing methods such as machining, forging or welding
are used, annealing is often required before the process starts, and the high
temperature corrosion and creep resistance of the parts will be affected. The
results of additive manufacturing of IN718 alloy show that the mechanical
properties have not been sacrificed and can even exceed the performance of cast
or forged parts. In addition, IN718 is a typical difficult-to-machine material
due to its high cutting temperature and serious work hardening. For the complex
geometries usually required in aerospace applications, the manufacture of IN718
parts is often very difficult and costly.
