Nimonic 115 Alloy Sheet
Nimonic 115 alloy daim ntawv yog npib tsib xee-chromium-cobalt-molybdenum alloy uas tuaj yeem nag lossis daus- tawv. Alloy 115 yog ib qho creep-tiv taus alloy tsim rau siab -kev pabcuam kub txog 1010℃. Haum rau oxidation tsis kam thiab siab -kub lub zog.
Nws tau tsim los muab tso rau hauv qhov kub tshaj plaws ntawm lub turbine, uas muaj kev ntxhov siab ntau tshaj plaws. Cov neeg siv khoom uas nug txog cov khoom siv no yuav luag tsuas yog siv nws rau siab -kub load- cov kabmob hauv cov tshuab dav hlau thiab cov roj turbines. Qhov no lees paub tias nws tsim nyog rau kev ua haujlwm ntev - nyob rau hauv cov xwm txheej hnyav.
Tsis tas li ntawd, hais txog cov txheej txheem kev kho cua sov, Alloy 115 yog cov tshuaj annealed ntawm 1190℃(2175℃F) rau 1 1/2 1 teev, huab cua-cooled rau 1099℃(2010℃F), tuav ntawm 1099℃(2010℃F) rau 61 xuab moos {cooled. Vim yog cov txheej txheem nyuaj me ntsis, tus nqi ua haujlwm yog siab dua li qhov siab ntawm - kub alloys.
Lork muab cov qauv thiab specifications
Feem ntau, Nimonic 115 alloy nplooj ntawv peb muab raws li tus qauv AMS 5829 (feem ntau siv rau aerospace nyias nyias). Xwb, DIN 2.4636 lossis DIN 17752 kuj muaj.
Peb cov ntawv tuab tshwj xeeb: Cov ntawv nyias nyias feem ntau yog li ntawm 0.5mm txog 6mm, thaum nruab nrab -cov ntawv tuab yog 6mm thiab siab dua. Peb muab ob hom ntawv: txias- dov (nqus nto, nruj tuab tolerances) thiab kub- dov (tej zaum yuav muaj oxide nplai rau ntawm qhov chaw).
Peb cov kev xaiv tiav saum npoo: 115 alloy rau aerospace daim ntawv thov feem ntau yuav tsum tau annealing, pickling, sib tsoo, los yog polishing. Rau daim ntawv thov hniav, qhov saum npoo yuav tsum tsis muaj microcracks, thiab nws yuav tsum tau txiav txim siab seb qhov kev ntsuas qhov tob tob yog qhov yuav tsum tau ua.

Weldability
Yuav tsum muaj cov khoom siv hlau nplaum rau vuam yog yuav tsum tau - qhov no tuaj yeem yog qhov sib tw alloy lossis cov muab tub lim nrog cov nickel siab, cobalt, molybdenum, thiab chromium cov ntsiab lus. Cov txheej txheem vuam tsim nyog suav nrog cov roj hlau- arc vuam, roj-tungsten arc vuam, submerged-arc vuam, thiab cov hlau thaiv- arc vuam.
Annealing
Nimonic 115 yog cov tshuaj annealed ntawm 1190℃(2175℃F) ua raws li qhov txias txias.
Ua haujlwm txias
Cov txheej txheem txheem txheej txheem yog siv rau kev ua haujlwm txias Nimonic 115. Kev siv cov pa roj carbon monoxide dawb tsis pom zoo, vim tias lawv tuaj yeem ua rau galling. Galling tuaj yeem txo qis los ntawm kev siv cov khoom muag muag thiab hnyav- lub luag haujlwm lubricants.
Vuam
Vuam cov tswv yim pom zoo rau Nimonic 115 suav nrog roj-tungsten arc vuam, roj hlau-arc vuam, submerged-arc vuam, thiab cov hlau thaiv- arc vuam. Kev siv cov hlau nplaum sib txuam yog pom zoo rau cov txheej txheem vuam, thiab cov hlau nplua nuj nyob hauv Ni, Co, Cr, thiab Mo tuaj yeem siv thaum tsis muaj cov hlau sib txuam.
Kev tsim
Cov txheej txheem ib txwm siv thiab hnyav -cov roj nplua nyeem yog siv rau kev tsim cov txheej txheem ntawm Nimonic 115, vim nws muaj qhov zoo ductility. Cov cuab yeej muaj zog tau pom zoo rau cov hlau no vim tias nws muaj zog dua li cov hlau uas muaj feem ntau. Tom qab kev tsim cov txheej txheem, tag nrho cov kab ntawm cov roj nplua nyeem yuav tsum tau muab ntxuav kom tsis txhob embrittlement ntawm cov hlau.
Machineability
Nimonic 115 yog machined los ntawm cov pa machining txoj kev. Cov hlau no muaj qib siab dua ntawm gumminess thiab lub zog thiab ua haujlwm - hardened thaum lub sij hawm machining txheej txheem. Cov cuab yeej siv thiab siv cov cuab yeej ua haujlwm hnyav thaum lub sijhawm ua haujlwm ua haujlwm kom txo qis kev ua haujlwm - hardening lossis chatter ntawm no alloy ua ntej txheej txheem txiav. Cov roj nplua nyeem hnyav yog tsim rau kev tho txawv, tapping, drilling, lossis broaching. Dej-raws li cov dej txias uas yog dej-raws li tau pom zoo rau kev ua haujlwm siab -, xws li milling, sib tsoo, lossis tig.
