Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun.
The success of nuclear fusion technology will lead to the development of Inconel718 powder.
Nickel-based superalloys are the most widely used. The main reason is that,
one is that more alloying elements can be dissolved in the nickel-based alloy,
and it can maintain good structural stability; the other is that it can form a
coherent and ordered A3B-type intermetallic compound γ[Ni3(Al, Ti)] As a
strengthening phase, the alloy can be effectively strengthened and obtain higher
high temperature strength than iron-based superalloys and cobalt-based
superalloys; thirdly, nickel-based alloys containing chromium have better
oxidation and resistance than iron-based superalloys.
Nickel-based alloys contain more than ten elements, of which Cr mainly plays
an anti-oxidation and anti-corrosion role, and other elements mainly play a
strengthening role. According to their strengthening action mode, they can be
divided into: solid solution strengthening elements such as tungsten,
molybdenum, cobalt, chromium and vanadium; precipitation strengthening elements
such as aluminum, titanium, niobium and tantalum; grain boundary strengthening
elements such as boron, zirconium, Magnesium and rare earth elements, etc.
In terms of smelting: in order to obtain more pure molten steel, reduce gas
content and harmful element content; at the same time, due to the presence of
easily oxidizable elements such as Al and Ti in some alloys, it is difficult to
control non-vacuum smelting; it is also to obtain better thermoplasticity ,
Nickel-based heat-resistant alloys are usually smelted in a vacuum induction
furnace, and even produced by vacuum induction smelting plus vacuum consumable
furnace or electroslag furnace remelting.
In terms of deformation: forging and rolling processes are used. For alloys
with poor thermoplasticity, they are even rolled after extrusion and billeting
or are directly extruded with mild steel (or stainless steel) sheathing. The
purpose of deformation is to break the casting structure and optimize the
Casting: usually use a vacuum induction furnace to smelt the master alloy to
ensure the composition and control the gas and impurity content, and use the
vacuum remelting-precision casting method to make parts.
Heat treatment: Wrought alloy and some cast alloys need to be heat treated,
including solution treatment, intermediate treatment and aging treatment. Take
Udmet 500 alloy as an example. Its heat treatment system is divided into four
stages: solution treatment, 1175℃, 2 hours, Air cooling; intermediate treatment,
1080°C, 4 hours, air cooling; primary aging treatment, 843°C, 24 hours, air
cooling; secondary aging treatment, 760°C, 16 hours, air cooling. In order to
obtain the required organizational state and good overall performance.

The COVID-19 pandemic has affected economies and chemical companies in many countries around the world. Measures such as extending holidays and resuming work were taken to control the development of the epidemic, and the normal operation of some chemical enterprises was also affected to some extent.
We provides high quality Inconel718 powder with reasonable price. “In order to feedback to old customers, the company is still in full operations to provide Inconel718 powder with competitive price.” said Olina, the sales manager.
Chemical production is highly dependent on transportation, and the epidemic affects the circulation of people and materials first. Predictably, none of this is rosy. In densely populated areas with large mobility, the situation of epidemic prevention and control becomes more severe in the later stage.
