1. Dab tsi yog ib tus nickel-based supalloy?
2. Yuav ua li cas qhov tsis zoo ntawm Nickel-based supalloys?
Tus nqi siab: Kev tsim khoom yuav tsum muaj qhov tsawg thiab kim tshaj plaws (E {{}}} Cov txheej txheem zoo li lub tshuab nqus thiab cov kev sib tw ua kom zoo nkauj {2}
Nyuaj machining: Lawv lub zog siab thiab Hardness - ua rau lawv nyuaj rau cov cuab yeej (e}
Kuj tseem ceeb ntom: Nrog lub ntom ntom ntawm ~ 8 . 2}}}}}} g.
Ib puag ncig rhiab heev: Raug rau kev xeb ib puag ncig (e {.}}}
Kev Pab Cuam Tshuam: Cov ntsiab lus tseem ceeb xws li cobalt thiab rhenium yog tsis tshua muaj, cov kev pheej hmoo txaus ntshai los muab cov saw hlau thiab kev ua kom ntev.
{{03. Dab tsi lub hardness ntawm nickel-based supalloys?
Chav Kub Kub: Feem ntau yog li ntawm200-400 HB (Brinell Hardness)lossis30-45 HRC (Rockwell C), nyob ntawm cov alloy thiab cua sov . Piv txwv li, thaum tshav kub tau ua tiav, thaum ua kub yaj.
Kev Kub Siab Lub Hardness High: Cov allots khaws lub zog tseem ceeb ntawm kev kub siab (e {{}}} kub}
4. Yuav ua li cas qhov ntom ntawm Nickel-based supalloys?
5.} waht cov muaj pes tsawg leeg ntawm cov npib tsib xee-based supalloy?
Npib tsib xee (ni, 50-70%): Ua cov hauv paus matrix, muab kev daws teeb meem thiab ruaj khov ntawm qhov kub siab .
Chromium (CR, 10-20%): Txhim kho kev xeb thiab oxidation tsis kam los ntawm kev tsim cov kev tiv thaiv kev tiv thaiv cov txheej txheem tiv thaiv .
Cobalt (CO, 5-15%): Txhim kho siab kub lub zog thiab ruaj khov lub crystal qauv .
Molybdenum (mo) lossis tungsten (w, 1-10%): Ntxiv dag zog rau lub matrix los ntawm cov khoom siv khov kho .
Aluminium (Al) thiab titanium (ti, 1-5% txhua): Daim 'precipitates (Ni₃ (Al, Ti)), tus tseem ceeb me) rau cov hnub nyoog ua kom tawv thiab ntxiv dag zog.
Niobium (nb, 1-5%): Cov ntawv '' precipitates (Ni₃nb) hauv alloys zoo li Inconel 718 los txhim kho lub zog {}}
Rhenium (re, 0.5-3%): Txhim kho creep tsis kam thiab ductility nyob rau hauv cov kev siv kub siab-kub, ib txwm muaj nyob rau hauv ib leeg-crystal alloys.
Cov pa roj carbon (c, 0.03-0.2%): Cov qauv carbides (e {{. g}}}}}, mc, m₂₃c₆) los txhawb cov hmoov nplej {}}
Kab kawm (e {{. g.}}, zr, Hf, B,<1% total): Ntxiv dag zog rau cov ciaj ciam lossis hloov oxidation tus cwjmwm zoo .
