Dab tsi yog inconel 718 siv rau?
1.Txhua: Inconel 718 yog feem ntau muaj cov npib tsib xee, nrog cov roj ntsha chromium, hlau, molybdenum, xws li ntxiv ntawm lwm yam, xws li txhuas thiab titanium. Cov ntsiab lus sib txuas ua ke rau cov khoom muaj txiaj ntsig. Lub rooj qhia cov lus sib xyaw ntawm Inconel 718.
2.High-kub lub zog: inconel 718 khaws nws lub zog thiab cov khoom siv tshuab ntawm cov kev siv kub thiab cua sov, xws li roj turbines, thiab cov foob pob hluav taws. Cov 'precipitates, daim foos twg thaum kev kho cua sov, ua raws li kev cuam tshuam rau kev tshem tawm cov kev tshem tawm txawm tias muaj qhov kub thiab txias. Nyob rau hauv huab kev ua hauj lwm kev mob, cov cuab yeej no ua kom muaj kev ncaj ncees ntawm tseem ceeb aeroeengine cov khoom siv, xws li cov hnab tawg ntawm cov tshuab lim thiab hluav taws xob.
3.
Corrosion Kuj: Cov alloy no ua rau muaj kev tiv thaiv corrosion thiab oxidation nyob rau hauv ntau qhov chaw, acids, thiab kev kub kub kub. Aero-engines ntsib ib puag ncig kev ntxhov siab qhov chaw nyob qhov twg oxidation thiab corrosion muaj peev xwm txo kev nyuaj siab ua tau zoo thiab ua kom tsis tu ncua. Nickel-based supalloys tiv thaiv oxidation thiab corrosion ua tsaug rau cov txheej oxide uas ua rau lawv nto. Cov khoom siv alloy, tshwj xeeb chromium, thiab txhuas, tsim cov teeb meem oxide ruaj khov uas ua raws li kev cuam tshuam, tiv thaiv kev cuam tshuam ntxiv thiab ua kom muaj kev pabcuam ntev ntxiv.
4.
Qoob qaug zog: Incmel 718 muaj kev nkees nkees tiv, uas txhais tau tias nws tuaj yeem tiv thaiv kev ntxhov siab ntau dua tsis tau ua tsis tiav. Cov cuab yeej no ua rau nws haum rau Cyclic Chaw thau cov ntawv thov, xws li drickine disks thiab rotor tuaj. Cov khoom siv alhoy ua haujlwm hauv synergy los tsim cov microj kev tsim kho microstructure muaj cov khoom siv daws tau, tawg 'precipitates, thiab carbides. Lub microstructure tshwj xeeb ua rau lub superalloys 'exceplection high-kub lub zog thiab kuj mus rau kev quav ntsej muag.
5.
Weldability: Inconel 718 tuaj yeem welded siv ntau hom kev kawm, ntshav arc vuam (paw), thiab electron nqaj vuam (EBW). Txawm li cas los xij, cov txheej txheem vuam kom zoo thiab kev kho cua sov tom qab Weld kom ntseeg tau cov khoom zoo tshaj plaws.
6.
Cov ntawv thov: Inconel 718 tau siv dav hauv kev siv lub dav hlau, xws li cov dav hlau cav, kev siv hluav taws xob, thiab cov foob pob hluav taws xob. Nws tseem ua haujlwm hauv cov roj thiab roj kev lag luam, suav nrog li qub, thiab cov cuab yeej downhanole. Lwm yam kev siv suav nrog cov kev ua tau zoo hauv tsheb, nuclear reactors, thiab cov khoom siv tshuaj lom neeg.
7.
Kev Kho Cua Sov: Inconel 718 undergoes ib nag lossis daus ceev ceev kom txhim kho nws cov khoom siv neeg. Qhov kev kho cua sov no cuam tshuam nrog anchaling ntawm ib qho kub tshwj xeeb ua raws li kev laus los txhim kho lub zog xav tau thiab Hardness.
