Txheej txheem cej luam ntawm Incone l625 nta thiab daim ntawv thov teb:
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 kev tiv thaiv corrosion zoo heev thiab siab oxidation zog, zoo tensile zog thiab qaug zog zog los ntawm qis kub 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.
Incone l625 hom zoo sib xws:
NS336 GH3625 GH625 (Tuam Tshoj), NC22DNb (Fabkis), W.Nr.2.4856 (Lub Tebchaws Yelemees)
Inconel625 metallographic qauv:
Cov qauv ntawm cov hlau nyob rau hauv lub xeev cov tshuaj yog ib tug austenite matrix thiab ib tug me me ntawm TiN, NbC, thiab M6C theem. Tom qab kev laus mus ntev ntawm 650 ~ 900 degree, cov theem precipitated yog ', δ, M23C6, thiab M6C.
Inconel625 txheej txheem kev ua tau zoo thiab cov kev xav tau:
1. Cov hlau no muaj cov khoom txias thiab kub ua kom zoo, thiab cov cua kub kub rau steel ingot forging yog 1120 degree.
2. Qhov nruab nrab grain loj ntawm lub alloy yog ze ze rau lub deformation degree thiab zaum kawg forging kub ntawm lub forging.
3. Cov alloy muaj kev ua haujlwm zoo vuam. Nws tuaj yeem siv rau argon arc vuam nrog tungsten electrode lossis cov hlau no ua cov khoom ntxiv hauv qhov chaw tiv thaiv. Brazing kev twb kev txuas thiab kuj seam welding kuj siv tau.
4. txheej txheem kev kho deg: Thaum tshem cov oxide nplai ntawm cov hlau nplaum, nws yog thawj zaug ntxuav nrog alkali, thiab tom qab ntawd muab cov nitric acid, hydrofluoric acid-aqueous tov.
5. Thaum cov nqi ua haujlwm ntau dua 15% thaum lub sijhawm ua haujlwm txias ntawm cov hlau, kev kho annealing yuav tsum tau nqa tawm tom qab ua haujlwm kub.
