Inconel 718 Tilmaamaha
Inconel 718 waa da'da adkeynaysa nikkel-ku-saleysan superalloy leh iska caabin heerkul sare oo heersare ah.Caadi ahaan loo isticmaalo warshadaha hawada sare, Inconel 718 waxay bixisaa awood heerkul sare leh iyo sidoo kale ductility heer sare ah ilaa 704°C/1300F.Dabiiciga ma aha magnet-ka.
Superalloy-ku-saleysan Nickel 718 ayaa iska caabin wanaagsan u leh oksaydhka iyo noocyada kale ee daxalka ee mishiinka jet-ka hawada sare iyo codsiyada marawaxadaha gaaska ee dhulka ku salaysan.Waa shayga ugu fiican ee codsiyada u baahan iska caabin heer sare ah oo ka dhan ah gurguurta iyo diiqada dilaaca (ilaa 982°C ama 1800F).Alloy 718 waxa ay si buuxda uga hortagtaa godadka iyo daxalka dilaaca ee sulfides, chlorides, carbon dioxide iyo bay'ada kale ee adag.
Inconel 718 waxay leedahay sifooyin dhammaystiran oo wanaagsan oo heerkulkiisu yahay -253 ilaa 700 °C, awoodda wax-soo-saarka ee ka hooseeya 650 °C waxay ku jirtaa darajada koowaad ee superalloys deformed, waxayna leedahay iska caabin daal wanaagsan, iska caabin shucaac ah, iska caabbinta oksaydhka, iska caabinta daxalka, iyo waxqabadka wanaagsan.Waxqabadka farsamaynta, waxqabadka alxanka iyo xasilloonida hay'adda muddada-dheer, waxay soo saari kartaa qaybo kala duwan oo leh qaabab adag, waxaana si ballaaran loogu adeegsaday heerkulka sare ee hawada, tamarta nukliyeerka, iyo warshadaha batroolka.
Inconel 718 alloy waa dabaysha adkaynaysa nikkel-chromium-iron alloy ka kooban niobium iyo molybdenum.Waxay leedahay awood sare, adkeysi wanaagsan iyo iska caabin daxalka ee heerkulka sare iyo hoose ee ka hooseeya 650 ℃.Xaaladdan waxaa laga yaabaa in xal la daweeyo ama roobabka la adkeeyo.
1. Si fudud loo farsameeyo
2. Xoog xajin sare, xoog daal, xoog gurguurta iyo xoog dilaac at 700 ℃
3. 1000℃ iska caabin oksidation sare
4. Kiimiko ahaan degan heerkulka hooseeya
5. Waxqabadka alxanka wanaagsan

Inconel718 Aagga Codsiga Alaabta
Sababtoo ah xoogga heerkulka sare ee 700 ° C, iska caabinta daxalka aad u fiican iyo hab fudud oo sahlan, waxaa si ballaaran loo isticmaali karaa munaasabado kala duwan oo loo baahan yahay.
1. marawaxadaha uumiga
2. Gantaal shidaal oo dareere ah
3.Cryogenic engineering
4.Acid deegaanka
5. Injineeriyada Nukliyeerka
