Iintsimbi eziqinileyo ezimbini, ezidume ngokudibanisa iimpawu ze-austenitic kunye ne-ferritic, zingubungqina bokuvela kwe-metallurgy, zibonelela ngokusebenzisana kweenzuzo ngelixa zinciphisa iingxaki ezikhoyo, rhoqo ngexabiso elikhuphisanayo.
Ukuqonda iDuplex Stainless Steel:
Eyona nto iphambili kwisiseko sentsimbi engagqwaliyo ephindwe kabini yisakhiwo sayo esincinci esinezigaba ezimbini, esidla ngokuba nomxube olinganayo we-austenite kunye ne-ferrite, nto leyo edala ukuvisisana kweempawu ezintle ngelixa inciphisa ubuthathaka. Ulwakhiwo lwe-metallurgical, nangona luxhomekeke kudidi oluthile, ludla ngokuquka ikhabhoni, i-manganese, i-silicon, i-chromium, i-nickel, i-phosphorus, kunye ne-sulfur, kunye nezongezo ezikhethiweyo ezifana ne-molybdenum, i-nitrogen, kunye ne-copper eziphucula ngakumbi iimpawu zezinto.
Umxholo Wembali Wentsimbi Engagqwaliyo Ephindwe Kabini:
Ukuqala kwee-alloys eziqinileyo ze-duplex kubuyela emva kwiingcamango zethiyori ngeminyaka yoo-1920, kwafikelela kwimveliso ebonakalayo ngeminyaka yoo-1930. Ekuqaleni yayixhomekeke kwimveliso ye-cast kunye nezicelo ezikhethekileyo ngenxa yomxholo ophezulu wekhabhoni, inkqubela phambili ekuguqulweni kwe-carburization ngasekupheleni kweminyaka yoo-1960 yazisa ixesha elitsha, yenza kube lula ukwenziwa kwee-alloys eziphantsi kwekhabhoni kunye nomxholo we-chromium kunye ne-nickel ophuculweyo, ngaloo ndlela kucocwa ibhalansi phakathi kwe-ferrite kunye ne-austenite. Umfuziselo wale ndlela yokuzivelela yiDuplex 2205, i-alloy yokuqala phakathi kweminyaka yoo-1970 eqhubeka nokuba negalelo ngenxa yokumelana kwayo nokugqwala okuphezulu xa kuthelekiswa namanqanaba emveli e-austenitic.
Iingenelo zeDuplex Stainless Steel:
Nangona ziyinxalenye encinci yemarike yentsimbi engagqwaliyo, ii-duplex alloys zibonelela ngeentlobo ngeentlobo zezinto ezifunekayo xa zithelekiswa nee-austenitic kunye nee-ferritic zemveli. Ezibalulekileyo phakathi kwezi zibonelelo ngamandla aphezulu, ukomelela okongeziweyo, kunye nokuguquguquka, kunye nokumelana nokugqwala okubonakala njengophawu oluphambili, olukhuphisana, ukuba aludluli, nolwamabakala e-austenitic. Ngaphezu koko, ukusebenza kakuhle kweendleko okukhoyo kwintsimbi ye-duplex, ngenxa yokusebenzisa ngobuchule izinto ezidibanisayo, kuyenza ibe lukhetho olunomtsalane kuzo zonke izicelo ezahlukeneyo.
Ukusetyenziswa kweDuplex Stainless Steel:
Ukuguquguquka kwentsimbi engagqwaliyo ye-duplex kuvakala kakhulu kumashishini amaninzi nakwiindawo ezahlukeneyo, ngenxa yokumelana kwayo nokugqwala okugqwesileyo, amandla aphuculweyo, kunye neempawu zayo ezingabizi kakhulu. Ngokuyintloko, imisebenzi yaselunxwemeni nakufutshane nonxweme, equka ukubhola ioyile, ukukhupha ityuwa, kunye nonyango lwamanzi, iphakathi kwabaxhamli abaphambili bobuchule bentsimbi ye-duplex. Ngokufanayo, ukusetyenziswa kwayo kufikelela ekucutshungulweni kweekhemikhali, ukusetyenziswa kwemikhosi yaselwandle, izixhobo zokulawula ungcoliseko, kunye nemizamo yokwakha, nto leyo egxininisa ukuba ikhona kuyo yonke indawo kwiindawo zoshishino zanamhlanje.
