Cov khoom no ua rau Inconel 718 zoo tagnrho rau cov ntawv thov hauv Aerospace, muaj cov tshuaj lom neeg thiab tiv taus oxidation ntawm ntug dej kub yog qhov tseem ceeb.
3. Dab tsi yog cov ntawv thov raug ntawm Inconel 718 daim hlau hauv kev lag luam?
Teb:
Inconel 718 daim hlau tau siv nyob rau hauv ntau lub zog uas muaj zog, tshav kub tawm, thiab corrosion tsis kam yog qhov tseem ceeb. Qee cov ntawv thov feem muaj xws li:
Aerospace: Siv rau hauv turbine yas, compressor hniav, thiab lwm yam siab {{}} kev cuam tshuam kev ntxhov siab hauv lub dav hlau tshuab thiab roj av.
Lub zog tiam: Inconel 718 yog siv rau hauv cov nroj tsuag fais fab, tshwj xeeb hauv cov roj turbines thiab commusction ua ke, qhov twg muaj cov khoom siv kub thiab txias.
Tshuaj lom neeg: Inconel 718 tau siv cov tshuaj tiv thaiv cov tshuaj lom neeg, kev sib pauv cua sov, thiab lwm yam khoom siv raug cov khoom siv hnyav thiab cov khoom kub siab.
Nuclear: Inconel 718 daim hlau tau siv nyob rau hauv Nuclear Reactor Txheej txheem uas tsis kam rau hluav taws xob thiab qhov kub siab yuav tsum tau ua.
Tubrog nkoj thiab ntug hiav txwv: Cov Alloy tseem siv nyob rau hauv ib puag ncig cov neeg muaj ib puag ncig uas ob qho siab - kub thiab corrosion tsis kam yog qhov tseem ceeb heev.
4. Dab tsi yog ASTM B575, thiab nws cuam tshuam li cas rau inconon 718?
Teb:
ASTM B575 yog kev tshwj xeeb rau Nickel {{chromium alloys hauv phaj, thiab cov txheej txheem kho mob txhua yam rau cov ntaub ntawv no. Inconel 718, nyob rau Astm B575, yog tsim nyob rau hauv phaj thiab tuaj yeem siv rau hauv phaj uas xav tau siv rau oxidation, corrosion, thiab siab-}}}}} qhov chaw dej khov. Qhov kev qhia tshwj xeeb tias cov khoom uas ua tau raws li cov ntawv tseem ceeb hauv kev ua haujlwm tseem ceeb hauv kev lag luam tseem ceeb hauv kev lag luam tseem ceeb, thiab lwm yam siab {} kev lag luam ntxhov siab.
5. Dab tsi yog cov kws kho tshuab ntawm inconel 718, thiab lawv yuav ua li cas txhawb nws kev ua tau zoo hauv kev ua haujlwm siab?
Teb:
Inconel 718 yog paub rau nws cov khoom siv neeg zoo tshaj plaws, tshwj xeeb tshaj yog thaum nce kub. Cov khoom tseem ceeb xws li muaj:
Lub zog tensile: kwv yees li 1,270 MPa ntawm chav sov, thiab nws tswj hwm lub zog siab txawm nyob rau ntawm ntug dej kub.
Tos lub zog: ncig 1,100 MPa, uas ua kom ntseeg tau cov khoom tuaj yeem tiv thaiv tau siab thiab kev ntxhov siab tsis muaj dab tsi los yog deforming.
Emongation: Inconel 718 muaj qhov ductility zoo (txog 15-20% elongation), uas tso cai rau nws nqus kom muaj kev ntxhov siab thiab deformation yam tsis muaj kev ua tsis tiav.
Cais tawm tsam: Kev tiv taus zoo heev rau nkag, ib daim ntawv ntawm deformation uas tshwm sim thaum cov ntaub ntawv raug nthuav tawm kom muaj kev ntxhov siab tas li thaum kub. Qhov no ua rau Inconel 718 qhov zoo tagnrho rau cov khoom sib xyaw uas ua haujlwm hauv qhov siab- qhov chaw ncua dej kom ncua.
Hardness: lub alloy tuaj yeem kub ntxhov tuaj cua sov -}}}}}}}}}}} Txoj kev hnav thiab kev yaig hauv cov ntawv thov Turbines thiab reactors.
Cov cuab yeej siv cov khoom siv no ua kom pom tias nws ncaj ncees thiab ntseeg tau cov ntaub ntawv tseem ceeb rau kev siv cov ntaub ntawv tseem ceeb hauv kev ua lag luam, thiab kev ua haujlwm loj.
