Kev ua haujlwm thiab kev kho cua sov
Inconel718 alloy yog cov khoom siv nyuaj rau kev ua haujlwm hauv kev ua haujlwm.
preheat
Qhov saum npoo ntawm lub workpiece yuav tsum tau ntxuav ua ntej thiab thaum lub sij hawm cua sov txheej txheem kom huv si nto. Yog hais tias qhov cua sov ib puag ncig muaj leej faj, phosphorus, txhuas los yog lwm yam uas tsis muaj melting point hlau, Inconel718 alloy yuav nkig. Cov impurities tuaj ntawm cov xim pleev xim, chalk, lubricating roj, dej, roj, thiab lwm yam. Cov ntsiab lus ntawm cov roj sulfur yuav tsum tsawg. Piv txwv li, cov ntsiab lus impurity ntawm cov roj av liquefied roj av thiab cov nkev ntuj yuav tsum tsawg tshaj li 0.1%, cov ntsiab lus sulfur ntawm lub nroog cov pa yuav tsum tsawg dua 0.25g/m3, thiab cov ntsiab lus sulfur roj av yuav tsum tsawg dua 0.5%.
Lub tshuab hluav taws xob rau cua sov yuav tsum zoo dua muaj peev xwm tswj tau qhov kub thiab txias dua. Lub cub tawg yuav tsum yog nruab nrab lossis tsis muaj zog alkaline, thiab cov roj hauv lub cub tawg yuav tsum tiv thaiv kom tsis txhob muaj qhov hloov pauv hauv oxidizing thiab txo cov khoom.
Thermal ua
Qhov tsim nyog kub ua haujlwm rau Inconel718 alloy yog 1120-900 degree . Txoj kev txias tuaj yeem yog dej quenching lossis lwm txoj kev ua kom txias sai. Tom qab ua haujlwm kub, nws yuav tsum tau muab tso rau 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. Kev ua haujlwm hardening tus nqi ntawm Inconel718 yog ntau dua austenitic stainless hlau, yog li cov khoom siv ua haujlwm yuav tsum raug kho raws li, thiab yuav tsum muaj cov txheej txheem annealing nruab nrab thaum lub sijhawm ua haujlwm txias.
Kev kho cua sov
Kev kho cov tshuaj sib txawv thiab cov txheej txheem kev laus yuav tsim cov khoom sib txawv. Vim tias qhov qis qis ntawm "theem, Inconel718 alloy tuaj yeem tau txais cov khoom siv kho tshuab zoo tshaj plaws los ntawm kev kho mob mus ntev.
polish
Cov oxides nyob ze ntawm cov welds ntawm Inconel718 workpieces yog qhov nyuaj rau tshem tawm dua li cov hlau tsis muaj steel. Lawv yuav tsum tau polished nrog ib tug zoo abrasive siv. Ua ntej pickling nyob rau hauv ib tug sib tov acid ntawm nitric acid thiab hydrofluoric acid, cov oxides yuav tsum tau muab tshem tawm nrog sandpaper los yog pre-salted nyob rau hauv ib da dej ntsev. deal nrog.
tshuab
Lub machining ntawm Inconel718 yuav tsum tau ua tom qab kev daws teeb meem, thiab kev ua hauj lwm hardening ntawm cov khoom yuav tsum tau muab coj los xav. Tsis zoo li austenitic stainless hlau, Inconel718 yog qhov tsim nyog rau kev txiav qis qis.
vuam
Cov nag lossis daus hardening Inconel718 alloy yog qhov tsim nyog rau vuam thiab tsis muaj kev nyiam tawg tom qab vuam. Weldability, yooj yim ntawm kev ua, thiab siab zog yog qhov zoo ntawm cov khoom siv no.
Inconel718 yog tsim rau arc vuam, plasma vuam, thiab lwm yam. Ua ntej vuam, qhov saum npoo ntawm cov khoom yuav tsum huv si, tsis muaj roj stains, chalk marks, thiab lwm yam, thiab 25 hli cheeb tsam nyob ib ncig ntawm lub weld yuav tsum polished kom pom cov hlau ci.
Inconel625 nickel-raws li alloy
Txheej txheem cej luam ntawm Inconel625 yam ntxwv thiab daim ntawv thov thaj chaw:
Cov hlau no yog ib qho kev daws teeb meem ntxiv dag zog rau npib tsib xee-raws li deformed high-temperature alloy nrog molybdenum thiab niobium ua cov ntsiab lus tseem ceeb. Nws muaj corrosion kuj zoo heev thiab siab oxidation zog, zoo tensile zog thiab qaug zog zog los ntawm qhov kub thiab txias mus rau 980 degree, thiab yog ntsev resistant. Kev ntxhov siab corrosion hauv huab cua. Yog li ntawd, nws tuaj yeem siv dav hauv kev tsim cov tshuab aerospace, cov khoom siv hauv aerospace thiab cov khoom siv tshuaj.
