Inconel 718 Alloy: Adwumayɛ Hene wɔ High-End Industrial Sectors

Sɛ́ osutɔ-a ɛyɛ den nickel-chromium-dade a wɔde afra no, Inconel 718 abɛyɛ ade titiriw wɔ mfiridwuma mu mmeae a ɛkorɔn te sɛ ahunmu, ahoɔden, ne po mu mfiridwuma mu, esiane ne soronko a ɛkorɔn-ɔhyew ahoɔden, creep resistance, corrosion resistance, ne processability nti. Ɛboa kɛse ma wɔde nnwinnade titiriw di dwuma wɔ nneɛma a atwa yɛn ho ahyia a emu yɛ den ase.

 

Wɔ ahunmu adwumayɛ mu no, Inconel 718 yɛ "core framework" ma engine ne ahunmu ahyɛn. Wɔde yɛ nneɛma te sɛ turbine disks, blades, ne combustion chambers a ɛwɔ aero-engines mu, a ɛtumi yɛ adwuma pintinn wɔ ɔhyew a ɛkɔ soro (650-700℃) ne mmeae a nhyɛsoɔ kɛseɛ wɔ mu. Saa bere yi nyinaa, rɔke engine turbopumps, ahunmu hyɛn nhyehyɛe ho nnua, ne afã afoforo nso gyina sɛnea etumi gyina ɔhyew mu nsonsonoe a emu yɛ den ne nhyɛso a ɛkɔ soro ano so.

 

Alloy no nso ho hia saa ara wɔ ahoɔden adwumayɛbea. Nneɛma a ɛwɔ gas turbines, pressure vessels ne heat exchangers a ɛwɔ nuklea reactors mu a ɛyɛ hyew a ɛkorɔn, ne afei nso downhole safety valves a wɔde yi po mu ngo a emu dɔ-no nyinaa de ne ahoɔden a ɛko tia ɔhyew a ɛkɔ soro-ɔhyew a ɛkɔ soro, radiation, ne pressure a ɛkɔ soro no di dwuma de hwɛ hu sɛ wɔyɛ ahoɔden a ɛyɛ adwuma yiye na ahobammɔ wom.

 

Wɔ po so mfiridwuma mu no, mfaso a ɛwɔ Inconel 718 so wɔ po mu nsu a ɛko tia nsɛe mu no da adi kɛse. Wɔde di dwuma kɛse wɔ mpoano asɛnka agua no nhyehyɛe afã horow, po ase nsu afiri, ne po mu nsu a wɔde yi nkyene fi mu no mu, na ɛko tia bere tenten-nsu a ɛwosow wɔ po mu nneɛma a atwa yɛn ho ahyia mu no yiye.

 

Bio nso, wɔ mfiri a ɛyɛ-awieɛ a ɛkorɔn mu no, wɔbɛtumi ahunu no wɔ nneɛma a ɛyɛ pɛpɛɛpɛ te sɛ high-temperature die-casting moulds ne high-speed compressor impellers. Wɔ aduruyɛ mfiri (sɛ nhwɛso no, koma oprehyɛn nnwinnade) ne kar engine ahorow a ɛyɛ adwuma yiye-a ɛyɛ adwuma yiye no afã atitiriw mpo mu no, ekura gyinabea a ɛho hia esiane sɛnea ɛne nneɛma a nkwa wom hyia ne sɛnea ɛsakra wɔ adwumayɛ tebea horow a emu yɛ den mu nti.

 

Efi wim kosi po a emu dɔ so, efi ahoɔden ntini so kosi nnuruyɛ mfiri a ɛyɛ pɛpɛɛpɛ so no, Inconel 718 repue sɛ "tweatibo a aniwa nhu" a ɛde nnwuma a ɛkorɔn-awiei a ɛwɔ ne nyinaa-adwumayɛ a ɛkyɛn so no nkɔso ba.
