INCONEL Alloy 718: Cov Khoom Siv Thiab Kev Siv

INCONEL alloy 718: Khoom siv thiab cov ntawv thov

Yog tias koj tab tom nrhiav cov khoom siv uas tuaj yeem khaws lub zog siab dhau ntawm qhov kub thiab txias ntau, xav txog INCONEL alloy 718. Peb ua tibzoo saib nws cov yam ntxwv tseem ceeb.

INCONEL alloy 718 yog ib qho ntawm ntau qhov nickel-based superalloys muab los ntawm Corotherm. Nws cov yam ntxwv tshwj xeeb thiab qhov kev qhia tshwj xeeb txhais tau tias nws tau siv rau ntau qhov kev siv tshuab siab thiab qhov tseem ceeb hauv kev siv.

Nws feem ntau yog xaiv los ntawm kev tsim qauv tshuab ua tsaug rau nws lub zog loj hauv huab cua sov ntawm ob qho kawg ntawm lub spectrum. Nws tuaj yeem siv hauv qhov chaw ib puag ncig ntawm cryogenic txhua txoj hauv kev mus txog 1300 ° F / 704 ° C. Thoob plaws txhua qhov ntawm tag nrho nws cov khoom pov thawj tshwj xeeb ntawm cov khoom lag luam, cov khoom tensile thiab nkag siab. Nws tseem qhia tau zoo heev tensile thiab cuam tshuam lub zog.

Cov alloy yog ua los ntawm 50-55% npib tsib xee + cobalt (nrog rau cov cobalt txwv 1% max) thiab 17-21% chromium. Qhov kev sib xyaw ua ke muab cov khoom siv nws cov khoom tiv thaiv corrosion. Qhov no suav nrog kev ua haujlwm zoo rau kev tiv thaiv oxidation, ua kom nws tiv taus cov xov xwm corrosive nyob rau hauv ntau ntawm nws cov ntawv thov.

Qhov seem ntawm cov muaj pes tsawg leeg suav nrog niobium + tantalum (4.75-5.5%), molybdenum (2.8-3.3%) thiab titanium (0.65-1.15%), ntxiv rau lwm yam sib npaug. Nws yog lub zog thiab kev sib xyaw ua ke ntawm cov khoom, lub luag haujlwm rau superalloy cov khoom tsim nyog hauv kev xav tau.

Rov qab muaj lub zog

Cov khoom siv uas muaj hnub nyoog-hardenable nrog tsis muaj qhov cuam tshuam loj. Nws teb qeeb rau qhov tau kho nyob rau hauv txoj kev no, txhais tau tias nws tuaj yeem tau annealed thiab welded tsis muaj qhov tshwm sim tawv thaum lub sijhawm cua sov lossis cua txias.

Nws lub chav ua kom muaj zog sov tau zoo dua qub los ntawm kev kho tshav kub, ua kom nws tiv taus qhov huab ib puag ncig zoo. Yuav tsum siv cov kev kho cua sov kom sib txawv, nyob ntawm qhov kawg ntawm cov khoom siv - txoj kev sib txawv rau qhov tau txais qhov zoo tshaj plaws ntawm cov khoom zoo thiab cov kev nyuaj siab rau kev siv cov khoom siv siab, lossis rau qhov siab tshaj plaws cov txiaj ntsig rau siv nyob rau hauv chav tsev lossis cryogenic kub.

Ib qho ntawm qhov zoo ntawm INCONEL alloy 718 yog tias nws yog qhov muaj peev xwm thiab yooj yim rau kev ua haujlwm nrog. Nws qhia tau hais tias vuam cov yam ntxwv zoo, tshwj xeeb tshaj yog hais txog qhov nws tsis kam mus tom qab hlau txuas. Hauv kev sib piv rau lwm cov npib tsib xee superalloys, tshwj xeeb yog cov uas siv tawv los ntawm txhuas lossis titanium, nws yog qhov loj dua.

Vim tias nws tuaj yeem raug tsim kom yooj yim thiab nkag mus rau hauv cov khoom qhov chaw nyuaj, cov khoom siv nws tus kheej rau cov ntawv thov ua haujlwm siab.

Cov ntawv thov

INCONEL alloy 718 feem ntau yog siv hauv kev lag luam aviation thiab aerospace. Cov kws tsim choj tau saib xyuas tas li txhawm rau txhim kho kev ntseeg tau thiab ua tau zoo ntawm cov cav, tsis txhob hais txog lawv lub sijhawm ntev. Superalloys, thiab hauv tshwj xeeb cov hlau ci 718, raug xaiv rau lawv sib npaug ntawm tus nqi thiab kev ua haujlwm.

Nws yog qhov yuav tsum tau siv cov ntaub ntawv uas tuaj yeem khaws lawv lub zog thiab tawm tsam qhov kev xeb hauv qhov kub ntawm cov cav no. Cov ntaub ntawv siv nyob rau hauv cov xwm txheej nyuaj, nrog ob qho kev siv tshuab thiab kev nyuaj siab los txiav txim siab.

INCONEL alloy 718 zoo tagnrho rau siv nyob rau hauv cov xwm txheej no. Piv txwv, nws tau siv hauv dav hlau cav thiab qhov chaw ceev nrawm, nrog rau cov log, khawm ris, ntsuas qhov ntsuas, lub pob tw, lub tog raj thiab lub thoob. Nws kuj yog siv los ua engineering Cheebtsam rau cov kua-roj foob pob ua ntxaij, cov nplhaib thiab cov viav vias, nrog rau ntau cov ntawv tsim hlau qhov chaw rau cov tshuab raj, ob lub dav hlau thiab hauv av.

Lwm qhov kawg ntawm qhov ntsuas kub, INCONEL alloy 718 kuj tseem siv tau nyob rau hauv cryogenic tankage.
