Intsimbi engagqwaliyo yenye yezona zinto zisetyenziswa kakhulu kubunjineli banamhlanje, eyaziwa ngokumelana kwayo nokugqwala, ukuqina kwayo, kunye nokuguquguquka kwayo. Phakathi kweentlobo zayo ezininzi,intsimbi engagqwaliyo ye-austeniticIgqame njengeqela elisetyenziswa kakhulu, elifumaneka kuyo yonke into ukusuka kwizixhobo zasekhitshini ukuya kwizityalo zeekhemikhali, izixhobo zonyango, kunye nezixhobo zeenqwelo-moya.
Enye yezona mpawu zahlukileyo ze-austenitic stainless steel kukubaokungekho magnethiLe propati iyahlula kwezinye iintlobo zentsimbi engagqwaliyo ezifana neeklasi ze-ferritic okanye ze-martensitic, ezinomtsalane ngokwendalo. Kodwa yintoni kanye kanye eyenza intsimbi engagqwaliyo ye-austenitic ingabi namandla ombane?
Kweli nqaku, siza kuhlola isayensi yesinyithi emva kwendalo yayo engeyiyo imagnethi, indima yokudibanisa izinto ezifana ne-nickel kunye ne-nitrogen, iimeko ezinokutshintsha indlela esebenza ngayo imagnethi, kunye nesizathu sokuba amashishini axhomekeke kolu didi lukhethekileyo lwentsimbi engagqwali. Njengomvelisi ophambili wentsimbi engagqwali,I-SAKYSTELinika ulwazi olunzulu malunga nendlela ezakhiwe ngayo izakhiwo ze-austenitic kunye nendlela iimpawu zazo zemagnethi ezilawulwa ngayo kwizicelo zokusebenza okuphezulu.
1. Yintoni i-Austenitic Stainless Steel?
Intsimbi engagqwaliyo yase-Austenitic luhlobo lwentsimbi engagqwaliyo enomphungaityhubhiki ejonge ubuso (FCC)isakhiwo sekristale. Esi sakhiwo sincinci siqiniswa zizinto ezithile zokudibanisa—ikakhului-nickel, i-chromium, kwaye ngamanye amaxeshai-manganesekwayei-nitrogen.
Ulwakhiwo lwe-FCC lubalulekile kwi-okungekho magnethiindalo. Kolu lungiselelo, iathom nganye ijikelezwe zezinye ezili-12 kwi-cubic lattice, nto leyo ethintela ii-magnetic domains ukuba zilungelelane ngokulula. Oku kungabikho kolungelelwano lwe-domain yikona okuphelisa i-magnetism phantsi kweemeko eziqhelekileyo.
Iintsimbi ezingenasici zase-Austenitic zimelwe ziiklasi ezifana304, 304L, 316, 316L, 310S, 321, kunye ne-347Zisetyenziswa kakhulu kuba zidibanisa ukumelana nokugqwala okugqwesileyo, ukwakheka kakuhle, kunye namandla oomatshini kunye nokuziphatha kwazo okungenamagnethi.
2. Indima yoLwakhiwo lweCrystal kwiMagnetism
Ukuze siqonde ukuba kutheni i-austenitic stainless steel ingenamagnethi, kufuneka siqale sijonge ubudlelwane obuphakathiisakhiwo sekristale kunye nemagnetism.
Kwizinyithi, imagnetism sisiphumoulungelelwaniso lweedomeyini zemagnethi, eziziindawo ezincinci ngaphakathi kwezinto apho ii-electron spins zijongise kwicala elinye. Ukuze ezi domains zilungelelanise kwaye zivelise imagnetism, isakhiwo sekristale sesinyithi kufuneka sixhase olo lungelelwaniso.

Iintsimbi ezingenasici zeFerritic kunye neMartensiticyibaneityhubhikhi egxile emzimbeni (BCC) or i-tetragonal egxile emzimbeni (BCT)Olu lungiselelo luvumela iidomeyini zemagnethi ukuba zilungelelane ngokulula, nto leyo eyenza zibe nemagnethi enamandla.
-
Iintsimbi ezingenasici zase-Austenitic, ngokuchaseneyo, baneUlwakhiwo lwe-FCCUlungelelwaniso kunye nolungiselelo lweathomu kolu lwakhiwo luthintela ulungelelwaniso oluhambelanayo lwee-spin, okwenza izinto zibei-paramagnetic okanye i-non-magnetickubushushu begumbi.
Lo mahluko kwisakhiwo uchaza isizathu sokuba nangona zonke iintsimbi ezingenasici zinentsimbi—into enomtsalane—azizo zonke ezibonisa iimpawu zemagnethi.
3. Indima yeNickel kwi-Non-Magnetism
I-Nickel yeyona nto ibalulekileyo eyenza intsimbi engagqwaliyo ye-austenitic ingabi namandla ombane. Iyazinzisai-austenitic (FCC)isigaba sentsimbi kubushushu begumbi, nto leyo ethintela ukuba ingaguquki ibe yi-ferrite okanye i-martensite.
Ngaphandle kwe-nickel eyaneleyo, intsimbi engagqwaliyo idla ngokwenzekaizakhiwo ze-ferriticngexesha lokuqina, ezinomtsalane. Ngokongeza i-nickel eyi-8–12 ekhulwini, intsimbi igcina isakhiwo sayo se-austenitic nasemva kokuba ipholile, iqinisekisa ukuba ihlala ingenawo amandla ombane.
Umzekelo:
-
Uhlobo lwentsimbi engagqwaliyo engu-304iqulethe malunga ne-18% ye-chromium kunye ne-8% ye-nickel.
-
Uhlobo lwentsimbi engagqwaliyo engu-316yongeza i-molybdenum (iipesenti ezi-2–3) ukuze ikwazi ukumelana nokugqwala ngcono kodwa igcina malunga ne-10–14 yeepesenti ze-nickel ukuze ihlale i-austenitic kwaye ingabi nemagnethi.
Ngoko ke, i-nickel isebenza njenge-isizinzisievala intsimbi kwimo yayo engeyiyo imagnethi.
4. Kutheni iChromium yodwa inganelanga
Nangona i-chromium inika ukumelana nokugqwala ngokwenza ifilimu ye-oxide engashukumiyo phezu komphezulu, ayenzi intsimbi engagqwaliyo ingabi namandla ombane. I-Chromium yi-into eyenza i-ferrite, oko kuthetha ukuba ikhuthaza isakhiwo setyhubhu esigxile emzimbeni.
Kuphela xa i-chromium idityaniswe ne-nickel eyaneleyo apho i-alloy ephumayo ihlala i-austenitic kwaye ingabi yi-magnetic. Olu lungelelwaniso phakathi kwezinto ezenza i-ferrite kunye ne-austenite-stabilizing lubalulekile ekufezekiseni ukuziphatha okufunwayo okungekho yi-magnetic.
5. Indlela iNitrogen echaphazela ngayo iMagneticism
Uyilo lwe-alloy lwanamhlanje ngamanye amaxesha lusebenzisai-nitrogennjengenxalenye yokutshintsha i-nickel. I-nitrogen iyasebenzaisizinzisi se-austenitekwaye inokunciphisa imagnetism kwiintsimbi ezingasebenziyo ezinomthamo omncinci we-nickel.
Umzekelo, kwiintsimbi ezithile ezingama-200 ezingenasici (ezifana ne-201 okanye i-202), i-nitrogen inceda ukugcina isakhiwo se-austenitic kwaye inciphisa amandla ombane nokuba amanqanaba e-nickel anciphile. Nangona kunjalo, ezi alloys zisenokuba namandla ombane kancinci emva kokusebenza ngokubanda kakhulu ngenxa yotshintsho lwe-martensitic oluncinci.
6. Ngaba i-Austenitic Stainless Steel ingaba yiMagnetic?
Ngelixa intsimbi engagqwaliyo ye-austenitic iyintoi-non-magnetic kwimeko yayo efakwe i-anneal, ingaiba yimagnethi kancinciphantsi kweemeko ezithile. Oku kwenzeka xa ukuguqulwa koomatshini okanye umsebenzi obandayo utshintsha isakhiwo sekristale.
Xa intsimbi engagqwali ye-austenitic isetyenziswaigobile, itsaliwe, iqengqiwe, okanye yenziwe ngomatshini, uxinzelelo olunamandla lunokubangela ukuba ezinye zezakhiwo ze-austenitic (FCC) ziguquke zibei-martensite (BCT), nto leyo enomtsalane. Oku kubizwa ngokubai-martensite ebangelwa luxinzeleloukwakheka.
Njengokuba:
-
Ishiti yentsimbi engagqwaliyo ye-304 isenokungabi namandla ombane ngaphambi kokuba yenziwe kodwa ibonise amandla ombane amancinci emva kokuzoba okanye ukwenza nzulu.
-
Ibholthi yentsimbi engagqwaliyo engama-316 isenokungabi namandla kakhulu kodwa ibonise ukutsala okuncinci kwimagnethi kufutshane nendawo enemisonto apho umsebenzi obandayo uphezulu khona.
Oku akuchaphazeli ukumelana nokugqwala okanye ukusebenza kwezinto—kubangela kuphela impendulo ebuthathaka yemagnethi.
7. Ngaba iMagnetist ingasuswa?
Ewe. Ukuba intsimbi engagqwali ye-austenitic iba yimagnethi emva kokusebenza ngokubandayo, ipropati yayo engeyiyo imagnethi inokubuyiselwa ngeisisombululo sokucoca.
Ngethuba lale nkqubo, intsimbi iyafudunyezwa ukuze1050–1100°Cuze uphole ngokukhawuleza. Olu bushushu buphezulu luvumela isakhiwo se-martensitic ukuba sibuyele ngokupheleleyo kwisakhiwo sokuqala se-austenitic, sisuse i-magnetism.
Nangona kunjalo, kubalulekile ukuqaphela ukuba le ndlela isebenza kuphela kwiindidi ze-austenitic. Iintsimbi ezingenasici ze-Ferritic kunye ne-martensitic azinakwenziwa zingasebenzi nge-annealing kuba ulwakhiwo lwazo olusisiseko lune-magnetic ngokwemvelo.
8. Ubudlelwane Phakathi Kokwakhiwa kunye neMagnetism
Ukwakheka kweekhemikhali zentsimbi engagqwaliyo kudlala indima ebalulekileyo ekumiseleni indlela esebenza ngayo imagnethi. Ezi zinto zilandelayo zichaphazela ulwakhiwo lwe-austenitic kunye nemagnetism:
| I-elementi | Impembelelo kwiSakhiwo | Isiphumo seMagnetic |
|---|---|---|
| I-Nickel (Ni) | Iqinisa i-austenite | Yehlisa amandla ombane |
| I-nitrogen (N) | Iqinisa i-austenite | Yehlisa amandla ombane |
| I-Chromium (Cr) | Iifom ze-ferrite | Yandisa ubunewunewu |
| IManganese (Mn) | Ixhasa i-austenite | Yehlisa amandla ombane |
| Ikhabhoni (C) | Ixhasa i-martensite | Iyandisa amandla ombane xa iphezulu |
I-nickel ephezulu kunye ne-nitrogen zikhuthaza isigaba se-austenitic esingengomagnetic, ngelixa i-chromium okanye ikhabhoni egqithisileyo inokutshintsha ibhalansi iye kwisigaba se-ferritic okanye se-martensitic, nto leyo eyonyusa amandla emagnethi.

Ezi mpawu ziyenza ifaneleke kakhulu kwiindlela ezifuna amandla, ucoceko, kunye nokungathathi cala kwemagnethi kubaluleke ngokulinganayo.
12. Ukungangeni kweMagnetic ye-Austenitic Stainless Steels
I-magnetic permeability (µr) ye-austenitic stainless steel ilinganisa ukuba ingakanani i-magnetic field enokungena kwi-material. Kwii-non-magnetic grades, amaxabiso e-µr adla ngokuba1.0 ukuya kwi-1.02, oko kuthetha ukuba ziziphatha phantse njengomoya okwintsimi yemagnethi.
Ngokumataniswa:
-
Intsimbi engagqwaliyo yeFerritic: µr = 100 ukuya ku-2000
-
Intsimbi engagqwaliyo yeMartensitic: µr = 500 ukuya ku-2000
