Npib tsib xee raws li alloy: inconel690 muaj kev sib xyaw thiab cov ntawv thov qhia
Inconel690 muaj cov khoom siv tshuaj tiv thaiv kab mob antioxidant thiab kev nyuaj siab heev corrosion. Nws muaj qhov zoo heev corrosion tsis kam rau ntau cov xov xwm aqueous thiab cov cua sov siab. Tsis tas li ntawd, nws tseem muaj lub zog siab, nws yog xim hlau zoo nkauj ruaj khov thiab ua kom zoo dua qub.
Inconel690 Kev Siv Tshuaj:
Cov pa roj carbon C: Tsawg dua lossis sib npaug rau 0. 050
Chromium cr: 27-37
Nickel Ni: Matrix
Hlau Fe: 7-11
Manganese MN: Tsawg dua lossis sib npaug rau 0. 50
Silicon Si: tsawg dua los yog sib npaug rau 0. 50
Phosphorus p: tsawg dua lossis sib npaug rau 0. 02
Sulphur S: Tsawg dua lossis sib npaug rau 0. 015
Tooj liab Cu: tsawg dua los yog sib npaug rau 0. 5
Inconel690 Cov Khoom Siv Lub Cev:
Inconel690 ceev faj: 8.19g / melting taw tes: 1344-1377} degree
Inconel690 Elastic Modulus: 211 GPA thermal conductivity: 12.1 λ / (W · Alex)
Inconel69 {{4 4}} hardness: hrb85 thermal expansion coefficient (} degree): 14.0 x 10-6
Lub ntsiab tseem ceeb ntawm inconel 690: Nickel-based kub alloy incloy omoLel 690 nws tau ua tau zoo heev corrosion thiab thermal stability.
Inconel 690 alloy cov khoom pov thawj ua tau zoo corrosion tsis zoo nyob rau hauv ntau cov kev daws teeb meem aqueous thiab cov roj av ib puag ncig. Vim nws cov ntsiab lus chromium siab, nws ua rau muaj cov acidic tawm xws li nitric acid thiab hydrofluoric acid. Hauv hydrochloric acid, nws tuaj yeem tiv thaiv corrosion ntawm cov kev ua kom muaj ntau (li 15% lossis tsawg dua), thiab muaj cov pa hluav taws xob phosphoric ntawm chav tsev kub thiab nruab nrab kub. Txawm li cas los xij, nyob rau hauv cov daws teeb meem npau npau, nws tsuas tuaj yeem tiv thaiv cov kua roj ntau cov kua qaub.
Tus qauv ntawm cov yeeb nkab690 tom qab kev kho cov tshuaj yog Austenite + ib qho me me ntawm cov carbide + ib qho me me ntawm TI (CN). Thaum kev daws qhov kub thiab txias yog nruab nrab ntawm 950 ~ 1100 degree, cov noob loj tsis hloov ntau. Thaum kev daws qhov kub tshaj 1150 degree, qoob loo loj nce sai heev. Yog li ntawd, nws raug nquahu tias kev kho cov kev kho ntsuas kub tsawg dua 1100 degree.
Tom qab TT kev kho mob, CR23C6 precipitates ntawm cov ciaj ciam av, thiab qhov loj me nrog kev nce lub sijhawm kub thiab kev faib tshuaj morphology los ntawm ib nrab txuas ntxiv mus rau ib nrab. Tom qab kev kho mob ntawm 800 × 104 degree lossis siab dua rau 48 teev, qhov loj nce siab heev.
