Alloy 907 yeeb nkab yog tus muaj npe tshwj xeeb-hlau-cobasal superalloy cov yeeb nkab muaj txiaj ntsig, thiab kev ruaj khov ntawm kev nce kub. Cov khoom no ua rau nws tsis tseem ceeb hauv kev siv cov lag luam thiab iberospace, suav nrog:
Aerospace thiab roj turbines:
Ib daim ntawv thov tseem ceeb yog nyob rau hauv kev tsim khoom ntawm cov khoom siv tseem ceeb rau cov dav hlau thiab cov roj roj. Cov yeeb nkab siv rau cov roj hluav taws xob siab siab, xaim hniav Hniav txias Nplooj ntawv. Nws cov coefficient ntawm thermal expansion (CTE) minimizes cov kev hloov pauv tsis zoo nyob rau hauv kev sib tw ua kom tsis txhob muaj kev sib tw thiab kev tswj hwm kev ua haujlwm nrawm, ib puag ncig muaj cua sov.
Lub tshuab fais fab nuclear:
Alloy 907 Yeeb tau ua haujlwm hauv nuclear reactors thiab cuam tshuam cov tshuab, tshwj xeeb hauv txias loops thiab siab cov hlab ntsha. Nws txoj kev tawm tsam rau hluav taws xob-ua rau cov neeg tawg, ua ke nrog cov uas muaj cov kab mob uas muaj zog (suav nrog nrog nrog cov chaw tsis yooj yim ntawm cov kev tsis sib haum xeeb ntawm cov chaw ua haujlwm tsis zoo ntawm cov chaw ua haujlwm tsis zoo ntawm cov chaw ua haujlwm tsis zoo ntawm cov chaw ua haujlwm tsis zoo ntawm cov chaw ua haujlwm tsis zoo ntawm cov chaw ua haujlwm tsis zoo ntawm cov chaw ua haujlwm tsis yooj yim.
Tshuaj lom neeg thiab petrochemical ua:
Nyob rau hauv kev txhoj puab ib puag ncig, cov yeeb nkab siv rau kev thauj cov kua ntshav, xws li cov kua qaub, alkalis, thiab hydrocarbon derivatives. Nws txoj kev tawm tsam rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking (Sulc) hauv chloride-nplua nuj lossis cov nroj tsuag roj ntsha, thiab roj offshore / roj ua cov chaw.
Qhov Kub-Kub Ntxhua Cua Furnaces:
Lub alloy lub peev xwm los khaws lub zog ntawm 650℃(1,200℃f) ua rau nws cov pipes zoo tshaj plaws rau kev ua cua sov, thiab kev tso pa tawm hauv kev ua kom sov. Nws tiv thaiv oxidation thiab scaling txawm nyob rau hauv ncua ntev raug rau high-gases, txo cov kev xav tau kev pab.
Advanced Engineering thiab Ntsuas:
Vim nws cov khoom ruaj khov ruaj khov thiab sib xyaw nrog lwm cov ntaub ntawv, xws li cov khoom siv hluav taws xob siab thiab cov hluav taws xob kom huv yog qhov hloov kho kub thiab txias yog qhov tseem ceeb rau qhov raug. Nws tseem pom siv hauv cov ntawv thov iav-rau-hlau ntim cov ntawv thov, qhov twg nws cov CTE sib tw uas ntawm iav, tiv thaiv cov foob tsis ua haujlwm.
Alloy 907 yog npib tsib xee-cobalt-based-based supalloy, nrog ua tib zoo sib dhos muaj pes tsawg leeg tsim los txhim kho nws cov khoom siv kho tshuab thiab tshuaj lom neeg. Cov tshuaj lom neeg cov tshuaj lom neeg muaj pes tsawg leeg (los ntawm qhov hnyav feem pua) yog raws li hauv qab no:
Npib tsib caug (ni): 42.0–48.0%
Ua hauj lwm ua kev sib dhos ua ntej, muab cov Austenitic ruaj khov uas tiv thaiv kev txhim kho thiab tswj hwm ntawm qhov kub.
Hlau (FE): 25.0–31.0%
Ua rau muaj zog thiab tus nqi-ua hauj lwm zoo thaum txhawb nqa Alloy cov qauv kev ruaj ntseg.
Cobalt (CO): 10.0–12.0%
Txhim kho kom muaj zog kub-zog, thiab ua kom muaj zog, ua rau cov ntaub ntawv zoo tagnrho rau cov kev siv kub-kub.
Chromium (cr): 9.0–11.0%
Txhim kho corrosion thiab oxidation tsis kam los ntawm kev sib sau cov roj chomium oxide txheej rau saum npoo, tseem ceeb rau nrog nrog nrog thaj chaw hnyav thiab huab cua siab.
Titanium (ti): 3.15–4.15%
Ua raws li cov neeg sawv cev ntxiv dag zog los ntawm kev ua kom muaj nag lossis daus, piv, ni₃ti) uas txhawb kom lub zog tensile muaj zog thiab creep tsis kam.
Aluminium (AL): 2.2–2.8%
Ua haujlwm nrog titanium los txhawb rau kev ua phem los nag, Ntxiv txhawb zog. Nws tseem AIDS hauv oxidation tsis kam los ntawm kev tsim kom muaj kev tsim ntawm cov roj oxide txheej.
Cov Ntsiab Lus Me (Feem Ntau Txwv):
Cov pa roj carbon (c): tsawg dua los yog sib npaug rau 0.08% (tswj cov carbide tsim kom tsis txhob muaj brittleness)
Manganese (MN): tsawg dua lossis sib npaug rau 0.50% (txhim kho ductility thiab deoxidation)
Silicon (si): tsawg dua los yog sib npaug rau 0.35% (AIDS hauv DEWEIGIDATION thaum chaw tsim khoom)
Tooj liab (Cu): tsawg dua los yog sib npaug rau 0.50% (txo qis kom tsis txhob txo cov corrosion resistance)
Boron (b): tsawg dua los yog sib npaug rau 0.015% (txhim kho cov qoob loo qoob loo muaj zog)
Zirconium (ZR): Tsawg dua lossis sib luag rau 0.015% (ruaj khov nplej ciaj ciam thiab txhim kho cov creep resistance)
Qhov kev sib xyaw no meej meej ua kom tiav alloy 907 tus cwj pwm muaj zog, corrosion tsis kam, thiab thermal ruaj khov, ua rau nws cov khoom siv xaiv rau kev siv cov kev siv heev.
