316l alaab-qeybiyeyaasha tuubada gariiradda, Saamaynta Walxaha Alloying on Machinability of Austenitic Stainless Steel

Immisa jeer ayaa dhibaato wax soo saar ahi dhacday markii gariirad ama dhalaal cusub la geliyay wax soo saarka?Dhibaatooyinkani waxay noqon karaan jajabyo, dildilaacyo, burooyin, galitaanka alxanka oo liita, dusha sare ee korontolaydh liidata, iyo kuwo kale oo badan.Tijaabada adag, tijaabooyinka xajiska, iyo qaybaha isdhaafsiga biraha, iyo dib u eegista warbixinada tijaabada warshada waa habab caadi ah oo lagu go'aamiyo isha dhibaatada.Mararka qaarkood waxaa la helaa isha dhibaatada, laakiin inta badan wax aan caadi ahayn lama helo.Xaaladahan, dhibaatadu waxay ku jirtaa isku-dhafka birta, xitaa haddii daawadu ay ku dhex jirto qaybta la cayimay ee birta.

Maqaalkan, waxaan ku xaddidi doonaa doodayada birta aan lahayn austenitic, inkastoo qaar badan oo faallooyin ah ay sidoo kale khuseeyaan noocyada kale.Alaabooyin badan oo dhib leh ayaa ka baxay xakamaynta waana in lagu qeexaa qeexida macmiilka ama dalabka iibka.Ha u qaadan in daawaha aad iibsanayso laga sameeyay celceliska shay kasta.Laga soo bilaabo 1988-kii, biraha birta waxay lahaayeen barnaamij loo yaqaan "jaritaan alloy" kaas oo isticmaala ugu yaraan walxo alloying si looga hortago dillaaca kulul iyo qabowga duuban.
Naqshadeynta Fasalka Biraha birta ah ee Austenitic waxaa loogu talagalay inay bixiyaan iska caabin daxalka ah deegaanno badan, iska caabin u ah hydrogen iyo embrittlement at 885ºF (475ºC), xoog wanaagsan, ductility wanaagsan iyo adkaanta hoose.Birta aan-dhalin qaabka ugu fudud waa birta leh ugu yaraan 12% chromium.Tani waa waxa ka dhigaya birta aan fiicnayn inay u adkaysato miridhku waxayna u ogolaataa filim dadban inuu sameeyo.Birta aan lahayni waxay ka jirtaa saddex dawladood oo macdan ah iyadoo ku xidhan halabuurka iyo daawaynta kulaylka: ferritic, martensitic iyo austenitic.Magacyadani waxay tixraacayaan qaab-dhismeedka crystal: ferrite waa cubic-kubik-jidhka, austenite waa cubic waji-ku-salaysan, martensite waa habdhiska tetragonal qalloocan, taas oo ah, qaab-dhismeedka cubic-ku-jiidad-qalloocan wuxuu noqdaa mid-jirka.
Birta saafiga ah waxay leedahay qaab cubic oo jidhka ku salaysan waxayna ka jirtaa eber buuxda ilaa barta dhalaalkeeda.Marka walxaha qaarkood lagu daro, "rings gamma" ama austenite ayaa la abuuraa.Curiyayaashani waa kaarboon, chromium, nikkel, manganese, tungsten, molybdenum, silicon, vanadium iyo silikoon.Waxaa ka mid ah walxahan, nikkel, manganese, chromium iyo kaarboon waxay awoodaan inay ballaariyaan giraanta gamma-ga meesha ugu fog.Waa isku darka nikkel iyo chromium taas oo ka dhigaysa austenitic birta aan lahayn weji xuddun cubic laga bilaabo eber dhammaystiran ilaa barta dhalaalka.Waa giraanta gamma-ga oo ka sooca aloosyada ferritic-ga iyo kuwa martensitic ah.Maaddada chromium ee birta birta ah ee martensitic waa mid aad u cidhiidhi ah, 14-18%, waana inay ka kooban tahay kaarboon, sababtoo ah kaliya marka lagu kululeeyo xadkan ayaa la samayn karaa austenite saafi ah, si martensite lagu heli karo deminta.Alaabta Ferritic waxay leeyihiin wax ka hooseeya 14% ama ka sarreeya 18%.Beddelida walxaha alloying waxay bedeli kartaa tirada.Habka ugu caansan waa in la yareeyo karbohaydraytyadaada.
Biraha birta aan lahayn austenitic ee ugu caansan oo ku salaysan halabuurka 18-8, 18% Cr 8% Ni.Haddii maadada nikkel ee birta ay ka badan tahay 8%, waa austenitic, haddii maadada nikelku hooseeyo, ka dibna waa birta duplex, taas oo ah, austenitic oo leh jasiiradaha ferrite.Marka la eego 5% nikkel, qaabdhismeedku waa qiyaastii 50% austenitic, 50% ferritic, ka hooseeya 3% waxay noqotaa mid si buuxda u dhalaalaysa.Sidaa darteed, 8% nikkel ayaa saldhig u ah birta aan lahayn austenitic ugu jaban.
Marka walxaha alloying lagu daro birta, waxay qaadan karaan booska crystal ugu weyn.Kuwan waxaa loo yaqaanaa daawaynta beddelka iyo daawaynta waxay ahaanaysaa hal waji.Cutubyo kale ayaa yar oo ku filan inay ku habboonaadaan inta u dhaxaysa atamka, oo loo yaqaanno walxaha interstitial, iyo daawaha ayaa weli ah hal waji.Cutubyo kale ayaa isku dari doona si ay u sameeyaan kiristaalo u gaar ah oo ay sameeyaan wejiyo gaar ah.Weli qaar kale waxay u dhaqmaan sida wasakh gudaha daawaha, oo loo yaqaan ka mid noqoshada.
