316l ababoneleli betyhubhu ejiyileyo, isiphumo sezinto zokudityaniswa kwe-Alloying Elements kuMachinability of Austenitic Stainless Steel

Mangaphi amaxesha apho kukho iingxaki zemveliso xa iikhoyili ezintsha okanye inyibilika zifakwa kwimveliso?Ezi ngxaki zinokuba zikhefu, iintanda, i-burrs, ukungena kakubi kwe-weld, indawo engafanelekanga ye-electropolished, kunye nezinye ezininzi.Uvavanyo lokuqina, iimvavanyo ze-tensile, kunye namacandelo e-metallographic cross, kunye nokuphononongwa kweengxelo zovavanyo lwefektri ziinkqubo eziqhelekileyo zokumisela umthombo wengxaki.Ngamanye amaxesha umthombo wengxaki ufunyenwe, kodwa ngokuqhelekileyo akukho nto ingaqhelekanga ifunyenwe.Kule meko, ingxaki ilele ekubunjweni kwentsimbi, nokuba i-alloy ingaphakathi koluhlu oluchaziweyo lwentsimbi.

Kweli nqaku, siya kunciphisa ingxoxo yethu kwi-austenitic stainless steels, nangona amaninzi amagqabantshintshi asebenza nakwezinye iindidi.Izinto ezininzi ezinengxaki azikho kulawulo kwaye kufuneka zicaciswe kwiinkcukacha zomthengi okanye kwi-odolo yokuthenga.Musa ukucinga ukuba i-alloy oyithengayo yenziwe kumyinge woluhlu lwento nganye.Ukusukela ngo-1988, iintsimbi zokusila zinenkqubo eyaziwa ngokuba “yi-alloy chipping” esebenzisa ubuncinci bezinto ezixutyiweyo ukuze kuthintelwe i-embrittlement eshushu kunye nokuqhekeka okubandayo.
IBanga loYilo lwe-Austenitic stainless steels zenzelwe ukubonelela ukuxhathisa kwe-corrosion kwiindawo ezininzi, ukuchasana ne-hydrogen kunye ne-embrittlement kwi-885ºF (475ºC), amandla amahle, i-ductility efanelekileyo kunye nobunzima obuphantsi.Insimbi engenasici kwifomu yayo elula yintsimbi ene-12% yechromium ubuncinane.Yiloo nto eyenza insimbi engenasici ixhathise umhlwa kwaye ivumela ifilimu ye-passive ukuba yenze.Insimbi engenasici ikhona kwiindawo ezintathu ze-metallurgical ngokuxhomekeke ekubunjweni nasekuphathweni kobushushu: i-ferritic, i-martensitic kunye ne-austenitic.La magama abhekiselele kwisakhiwo sekristale: i-ferrite yi-cubic egxilwe ngumzimba, i-austenite yi-cubic ejongene nobuso, kwaye i-martensite yinkqubo ejijekileyo ye-tetragonal, oko kukuthi, isakhiwo esijijekileyo sobuso esigxininisekileyo siba ngumzimba.
Intsimbi esulungekileyo inomzimba ongaphakathi kwi-cubic shape kwaye ikhona ukusuka ku-zero ngokupheleleyo ukuya kwindawo yayo yokunyibilika.Xa izinto ezithile zongezwa, "amakhonkco e-gamma" okanye i-austenite yenziwe.Ezi zinto ziyi-carbon, i-chromium, i-nickel, i-manganese, i-tungsten, i-molybdenum, i-silicon, i-vanadium kunye ne-silicon.Phakathi kwezi zinto, i-nickel, i-manganese, i-chromium kunye nekhabhoni ziyakwazi ukwandisa iringi ye-gamma kude kakhulu.Ludibaniso lwenickel kunye nechromium eyenza iintsimbi ze austenitic stainless zijongane ne cubic ephakathi ukusuka kwiqanda ukuya kwindawo yokunyibilika.Yile ringi ye-gamma eyahlula iialloys ze-ferritic ukusuka kwi-martensitic.Umxholo we-chromium wentsimbi ye-martensitic incinci kakhulu, i-14-18%, kwaye kufuneka ibe nekhabhoni, kuba kuphela xa ishushu kolu luhlu inokuqulunqwa i-austenite ecocekileyo, ukuze i-martensite ifumaneke ngokucima.Iialloyi zeFerritic zinomxholo ongaphantsi kwe-14% okanye ngaphezulu kwe-18%.Ukutshintsha izinto ze-alloying kunokutshintsha uluhlu.Eyona ndlela iqhelekileyo kukugcina i-carbs yakho iphantsi.
Iintsimbi eziqhelekileyo ze-austenitic ezingenasici ezisekelwe ekubunjweni kwe-18-8, 18% Cr 8% Ni.Ukuba umxholo we-nickel kwintsimbi udlula i-8%, i-austenitic, ukuba umxholo we-nickel uphantsi, ngoko i-duplex steel, oko kukuthi, i-austenitic kunye neziqithi ze-ferrite.Kwi-5% ye-nickel, isakhiwo simalunga ne-50% ye-austenitic, i-50% ye-ferritic, ngaphantsi kwe-3% iba yi-ferritic ngokupheleleyo.Ngoko ke, i-8% ye-nickel isisiseko sezona zintsimbi ze-austenitic ezingabizi kakhulu.
Xa izinto ze-alloying zongezwa kwintsimbi, zinokuthatha indawo kwi-crystal ephambili.Ezi zaziwa njengeealloyi ezitshintshiweyo kwaye ialloyi ihlala ikwisigaba esinye.Ezinye izinto zincinci ngokwaneleyo ukuba zingene phakathi kweeathom, ezibizwa ngokuba yi-interstitial element, kwaye i-alloy ihlala isisigaba esinye.Ezinye izinto ziya kudityaniswa zenze ezazo iikristale ezizodwa kwaye zenze izigaba ezithile.Kanti abanye basebenza njengokungcola kwi-alloy, eyaziwa ngokuba yi-inclusions.
