Rau cov engineers hauv aerospace propulsion thiab lub zog tsim hluav taws xob, cov txheej txheem forging ntawmGH4169 alloyyog ib qho ntawm cov kauj ruam tseem ceeb tshaj plaws hauv kev tsim khoom. Loj - txoj kab uas hla xws li turbine disks, cav shafts, thiab bearing rings yog raug rau huab cua centrifugal thiab thermal stresses.
Cov ntsiab lus mob tseem ceeb rau cov neeg yuav khoom ntawm cov khoom forged muaj xws li:
* ** Macroscopic cais (qhov chaw): **Inbalances nyob rau hauv cov tshuaj muaj pes tsawg leeg ntawm ingot tuaj yeem ua rau cov ntsiab lus tsis muaj zog hauv zos.
** Internal porosity thiab inclusions: **Nkaum microscopic voids tuaj yeem dhau los ua cov ntsiab lus tawg hauv qab kev qaug zog.
* ** Tsis sib xws grain loj: **Qhov sib txawv ntawm cov qauv nplej tuaj yeem ua rau cov khoom tsis ruaj khov thiab ua rau lub neej ua haujlwm luv.
NtawmGnee Steel, peb tshem tawm cov kev pheej hmoo no. Peb siv siab -purityVIM+VARdual- melting ingots los xyuas kom meej tias txhua lub forged Cheebtsam ua tiav cov txheej txheem kev ncaj ncees uas yuav tsum tau rau lub hom phiaj- cov ntawv thov tseem ceeb.

GH4169 Alloy Forging Txheej Txheem Qhia
GH4169 Alloy Forging Txheej Txheem Qhia
GH4169 (sib npaug rau Inconel 718) yog npib tsib xee- hlau-chromium-raws li superalloy paub txog nws lub zog siab, zoo qaug zog, thiab zoo heev corrosion kuj mus txog 650℃. Vim nws qhov kev tiv thaiv siab rau deformation thiab nqaim kev ua haujlwm kub ntau, kev tswj xyuas meej ntawm cov txheej txheem forging yog qhov tseem ceeb kom tsis txhob muaj cov kab mob microstructural xws li cov nplej sib xyaw lossis cov kab nrib pleb.
Dab tsi yog qhov muaj pes tsawg leeg ntawm GH4169 alloy?
Cov tshuaj muaj pes tsawg leeg ntawm GH4169 alloy yog raws li nram no: Ni 53.44%, Cr 18.56%, Mo 3.02%, Nb 5.3%, Al 0.44%, Ti 1.04%, C 0.026%, P 0.005%, S 0.001%, B 0.002%, . Fe balance (w.
1. Kev npaj thiab cua sov
Kev tshuaj xyuas cov khoom: Cov khoom xa tuaj yuav tsum tau kuaj xyuas cov khoom muaj pes tsawg leeg, qhov loj ntawm cov nplej, thiab cov txheej txheem thawj zaug (ASTM 10).
Thaum pib cua sov:Preheating yuav tsum tau ua kom puas dendritic qauv. Ib txoj hauv kev zoo tshaj plaws yog homogenization kom ntseeg tau tias qhov kev faib tawm tsis sib xws ntawm theem (Ni3Nb), uas tswj cov qoob loo loj hlob.
Cov txheej txheem cua sov:Kev siv ntau- theem cua sov yog pom zoo los tiv thaiv thermal shock:
**Zone 1:**Preheat rau li 900-950 degree.
**Zone 2:**Thaum kawg cua sov mus rau 1000-1080℃(nyob ntawm lub forging theem).
Kev tswj qhov kub thiab txias:Yuav tsum tau tswj qhov kub thiab txias; Kev kub siab heev ua rau cov nplej coarsening, thaum qhov kub thiab txias dhau heev ua rau Laves theem tsim.

2. GH4169 Forging txheej txheem Parameters (kub ua hauj lwm)
Optimal Temperature Range:
Preliminary Forging:1050℃- 1100℃(High-kub theem, siv los rhuav tshem cov microstructure).
Qhov kawg Forging:950℃- 1020℃(Tsawg-kub theem, siv los kho cov nplej).
Tus nqi lim:Tsawg mus rau nruab nrab strain tus nqi yog nyiam, feem ntau nyob ib ncig ntawm 0.005–0.1 s⁻¹, los txhawb dynamic recrystallization (DRX) thiab tiv thaiv ndlwg localization.
Deformation tus nqi:Generally, a large deformation amount (>40% txo) yuav tsum tau ua kom tiav recrystallization thiab tau txais kev nplua -grained microstructure.
Txheej txheem:Cov txheej txheem feem ntau suav nrog kev ntxhov siab (rau ntsug compression) thiab ntau-theem tuag forging.
