Thaum cov ntawv thov cuam tshuam nrog huab cua kub, siab siab, khaus mechanical loads, lossis corrosive ib puag ncig, xaiv cov khoom siv los ua qhov kev txiav txim siab engineering tseem ceeb. Hauv cov xwm txheej xav tau no, Inconel 718 feem ntau suav hais tias yog ib qho kev daws teeb meem saum toj kawg nkaus -tier. Tsim los ua nag lossis daus-nickel hardened-raws li superalloy, Inconel 718 tau ua pov thawj nws tus kheej hauv kev lag luam uas tsis ua haujlwm tsis yog qhov kev xaiv. Tab sis nws puas yog cov khoom siv tiag tiag rau kev mob hnyav? Feem ntau, cov lus teb yog yog-thiab rau ntau qhov zoo- txhais tau tias yog vim li cas.
Ua ntej, siab - qhov kub thiab txias yog ib qho txiaj ntsig zoo ntawm Inconel 718. Tsis zoo li cov hlau tsis zoo li cov hlau tsis zoo lossis cov hlau alloy uas sai sai poob lub zog ntawm qhov kub siab, Inconel 718 tuav cov khoom zoo heev txog li 650-700℃. Qhov kev ruaj ntseg no tso cai rau cov khoom siv ua haujlwm tsis tu ncua nyob rau hauv tshav kub yam tsis muaj deformation ntau dhau, nkag mus, lossis poob ntawm kev thauj khoom -cov kabmob muaj peev xwm. Yog li ntawd, nws yog dav siv nyob rau hauv lub cav turbine, tso pa tawm, thiab siab -kub fasteners qhov twg thermal ntseeg yog qhov tseem ceeb.
Thib ob, Inconel 718 muaj qhov tshwj xeeb tiv thaiv rau kev nkag mus thiab kev ntxhov siab, uas yog hom tsis ua haujlwm nyob rau hauv ntev - lub sij hawm raug tshav kub thiab kev ntxhov siab. Hauv cov xwm txheej hnyav, cov khoom siv tsis tshua muaj kev thauj khoom tas li ib leeg; Lawv muaj kev vibration, siab hloov pauv, thiab thermal cycling. Inconel 718 ua tau zoo heev nyob rau hauv cov kev ntxhov siab ua ke, tiv thaiv kev pib tawg thiab ua kom tawg qeeb. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau aerospace, lub zog tsim hluav taws xob, thiab kev siv roj & roj qhov twg cov khoom yuav tsum ua haujlwm ntev xyoo ntawm kev ua haujlwm cyclic.
Lwm qhov tseem ceeb yog nws qhov zoo tshaj plaws corrosion thiab oxidation tsis kam. Ib puag ncig huab cua feem ntau suav nrog kev tawm tsam hnyav xws li cov kua qaub, chlorides, dej hiav txwv, lossis siab -kub oxidizing atmospheres. Lub siab nickel thiab chromium cov ntsiab lus ntawm Inconel 718 ua rau nws ua tau zoo nyob rau hauv ob qho tib si oxidizing thiab txo qhov chaw. Nws tiv taus pitting, kev nyuaj siab corrosion cracking, thiab degradation degradation, ua rau nws yog ib qho kev ntseeg siab rau cov khoom siv tshuaj, cov qauv sab nrauv, thiab siab - siab li qub.
Piv nrog rau ntau lwm cov npib tsib xee-raws li superalloys, Inconel 718 kuj sawv cev rau nws cov weldability kuj zoo. Cov khoom hnyav heev - cov xwm txheej feem ntau loj, nyuaj, lossis xav tau kev kho thaum lub sijhawm ua haujlwm. Inconel 718 cov nag lossis daus qeeb qeeb- tus cwj pwm tawv kom txo tau qhov kev pheej hmoo ntawm kev xa tawm -weld cracking, tso cai rau ntau txhim khu kev qha fabrication thiab txij nkawm. Cov yam ntxwv no txo qis kev pheej hmoo ntawm kev tsim khoom thiab muab kev tsim qauv yooj yim dua rau cov kws ua haujlwm ua haujlwm ntawm cov tshuab tseem ceeb.
Los ntawm kev pom ntawm daim ntawv thov, Inconel 718 tau siv tau ntau yam hauv lub tshuab aerospace, roj turbines, nuclear reactors, oilfield cov cuab yeej, siab hlab ntsha, springs, thiab siab - lub zog fasteners. Nws muaj peev xwm los ua ke lub zog, toughness, thiab corrosion kuj nyob rau hauv ib qho kev alloy ua rau nws haum rau ob qho tib si rotating thiab static Cheebtsam nyob rau hauv huab kev pab cuam tej yam kev mob. Ob peb cov ntaub ntawv muab xws li ib tug sib npaug profile profile nyob rau hauv thiaj li muaj ntau xav tau ib puag ncig.
Tus nqi feem ntau yog qhov kev txhawj xeeb. Thaum Inconel 718 yog kim dua li cov pa steels, huab cua - cov ntawv thov yuav tsum muaj kev xav txog kev ua neej nyob tsis yog tsom rau cov khoom siv thawj zaug. Lub alloy lub neej ua haujlwm ntev, txo cov kev xav tau ntawm kev saib xyuas, thiab txo qis kev pheej hmoo ntawm kev puas tsuaj loj feem ntau ua rau kev txuag nyiaj ntau dhau sijhawm. Hauv cov txheej txheem tseem ceeb, tus nqi poob qis lossis tsis ua haujlwm deb tshaj qhov kev nqis peev ua ntej hauv cov khoom siv ua haujlwm siab -.
Hauv kev xaus, Inconel 718 tsis yog tsuas yog haum rau cov xwm txheej huab cua xwb- nws feem ntau yog ib qho kev xaiv zoo tshaj plaws muaj. Nws cov pov thawj kev ua tau zoo nyob rau hauv qhov kub thiab txias, tsis kam mus rau qaug zog thiab corrosion, muaj zog weldability, thiab dav kev lag luam txais ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv rau ib puag ncig uas thawb engineering txwv. Rau cov ntawv thov uas muaj kev nyab xeeb, kav ntev, thiab ntev -lub sij hawm ruaj khov yog qhov tseem ceeb, Inconel 718 yog qhov tsis xav tau kev daws teeb meem.
