Inconel 718 cov ntaub ntawv qhia thiab daim ntawv thov
Hauv 718
Alloy 718 yog nag lossis daus-muaj zog nickel-raws li qhov kub thiab txias thiab muaj zog alloy
Nws muaj cov khoom zoo hauv qhov kub ntawm -253 txog 700 degree . Lub zog tawm los qis dua 650 degree yog thawj ntawm cov deformed superalloys. Nws kuj muaj kev qaug zog zoo, hluav taws xob tiv thaiv, oxidation kuj, corrosion kuj, thiab kev ua haujlwm zoo. , vuam kev ua tau zoo thiab lub sij hawm ntev kev ruaj ntseg, thiab tuaj yeem tsim ntau yam nrog cov duab nyuaj. Nyob rau hauv aerospace, nuclear zog, thiab roj av industries, nws tau lug siv nyob rau hauv lub saum toj no kub ntau yam.
Lwm qhov tshwj xeeb ntawm cov hlau no yog tias cov hlau alloy cov qauv yog tshwj xeeb tshaj yog rau cov txheej txheem thermal ua. Los ntawm kev paub txog cov txheej txheem nag lossis daus thiab kev sib cais hauv cov hlau thiab kev sib raug zoo ntawm cov qauv, txheej txheem, thiab cov khoom, cov txheej txheem tsim nyog thiab ua tau tuaj yeem tsim tau rau kev siv sib txawv. Muaj ntau yam khoom siv los ua kom tau raws li qib sib txawv ntawm lub zog thiab cov kev xav tau siv.
Alloy 718 corrosion kuj
Nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking thiab pitting corrosion nyob rau hauv ob qho tib si kub thiab tsis kub ib puag ncig, thiab nws oxidation kuj yog tshwj xeeb tshaj yog zoo nyob rau hauv high kub.

Alloy 718 ua
Thermal ua
Qhov tsim nyog thermal ua kub yog 1120-900 degree . Txoj kev txias tuaj yeem yog dej quenching lossis lwm txoj kev ua kom txias sai. Tom qab thermal ua, nws yuav tsum tau muab tshem tawm hauv lub sijhawm kom ntseeg tau tias qhov ua tau zoo tshaj plaws. Thaum lub sij hawm thermal ua, cov khoom yuav tsum tau rhuab mus rau lub sab sauv txwv ntawm ua kub. Txhawm rau kom cov plasticity thaum ua tiav, qhov kawg ua haujlwm kub thaum lub deformation mus txog 20% yuav tsum tsis txhob qis dua 960 degree.
Ua haujlwm txias
Kev ua haujlwm txias yuav tsum tau ua tom qab kev kho cov kua dej khov kho. Qhov kev ua haujlwm hardening yog ntau dua li ntawm austenitic stainless hlau. Yog li ntawd, cov cuab yeej ua haujlwm yuav tsum tau kho kom haum, thiab yuav tsum muaj cov txheej txheem annealing nruab nrab thaum lub sijhawm ua haujlwm txias.
Alloy 718 vuam txheej txheem
Cov hlau muaj qhov ua tau zoo welding zoo thiab tuaj yeem welded los ntawm argon arc vuam, electron beam vuam, seam welding, qhov chaw vuam thiab lwm txoj kev.
Alloy 718 qhov chaw kho cua sov txheej txheem
Kev kho cua sov ntawm aviation qhov chaw feem ntau yog ua raws li cov txheej txheem kev kho cua sov thiab kev kho cua sov ncaj qha.
