Taw qhia thiab cov ntawv thov ntawm kev kub kub alloys
Kev kub nyhiab alloys, tseem hu ua superalloys, yog chav kawm ntawm cov ntaub ntawv hlau uas tuaj yeem tswj tau lawv lub zog thiab corrosion tsis kam nyob rau hauv qhov chaw siab ib puag ncig.
Taw qhia thiab cov ntawv thov ntawm kev kub kub alloys
High-kub alloys yog hlau-raws li cov khoom siv uas tau siv ntau dua, thiab cov khoom siv tawm tsam ntau tshaj plaws, thiab corrosion tsis kam, thiab corrosion tsis kam .
Metallurgical Principles ntawm Kev Kub-Alloys
High-kub alloys feem ntau muaj lub ntsej muag-nruab nrab ntawm FCC cov qauv hauv FCC qauv tom qab muaj kev kub ntxhov ntawm kev txiav txim siab los ntawm lawv cov tshuaj muaj pes tsawg leeg, tab sis kuj cuam tshuam los ntawm kev kho cua sov, zam txim, thiab ua cov txheej txheem ua kom zoo nkauj.
Cov yam ntxwv thiab cov khoom ntawm kev kub-kub alloys
Dog dig hlau thiab titanium alloys tsis muaj zog txaus nyob rau qhov kub tshaj 540℃thiab tej zaum yuav raug puas tsuaj los ntawm corrosion.
Yog tias muaj zog yuav tsum khaws cia kom muaj kev tswj hwm kub siab (melting taw tes ntawm cov alloys feem ntau yog hais txog {{0}-based superalloys feem ntau yog xaiv.
Nickel-based superalloys tuaj yeem siv tau ntawm cov khoom kub siab dua li cov khoom lag luam .
Kev cobalt superalloys tuaj yeem siv los hloov chaw rau Nickel-based superalloys, nyob ntawm qhov xav tau thiab corrosion hom.
Ntawm qis dua kub, hlau-raws li superalloys muaj ntau cov kev thov tshaj li npib tsib xee thiab cob qhia thiab siv supalalloys {4}
Lub zog ntawm superalloys nyob ntawm tsis yog nyob rau ntawm kev kho tshuaj lom neeg, tab sis kuj yog cov txheej txheem ua tom qab kev kho cua sov, forging .
Cov hlau-npib tsib xee-based superalloys yog pheej yig dua li npib tsib xee thiab cobalt-based supalloys.
Txhawm rau txhim kho corrosion tsis kam ntawm cov kub, feem ntau cov txheej txheem superalloys muaj qee qhov nqi ntawm chromium .
Superalloys muaj cov oxidation siab tiv taus, tab sis hauv qee kis, corrosion resistance kub siab li cas los xij, superalalloys kom muaj coings .
Superalalloy txheej thev naus laus zis yog ib qho tseem ceeb ntawm nws daim ntawv thov thiab kev txhim kho {{uncoated superalallloys yog tsis muaj zog rau kev siv sijhawm ntev ntawm kev kub siab.
Nyob rau hauv superalloys, tshwj xeeb tshaj yog cov neeg laus, raws li cov khoom muaj ntau yam ntxiv, nrog qee cov alloys muaj txog li 14 lossis ntau dua tswj cov khoom.
Cov ntsiab tau siv nyob rau hauv superalloys, xws li npib tsib, Cobalt, molybdenum, molybium, feem ntau kim thiab sib txawv dhau sijhawm {}}
Cov ntawv thov ntawm Superalloys
Superallys muaj ntau yam kev siv hauv cov ntawv thov kub siab, suav nrog cov dav hlau, tshuaj lom neeg thiab petrochemical khoom.
Nws yog ib qho tseem ceeb kom nco ntsoov tias tsis yog txhua daim ntawv thov ntawm cov khoom siv kho mob rau cov khoom siv kho mob
Superalloys ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub vim lawv cov khoom lag luam tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv Aerospace, thiab siv tshuaj lom neeg {}}}
