Qhov sib txawv ntawm 690 thiab 706 inconel -} kev paub

1. Tshuaj lom neeg sib xyaw

Cov tub ntxhais sib txawv nyob hauv cov ntsiab lus ntawm chromium (CR), npib tsib), hlau (FE) txiav txim siab ncaj qha lawv corrosion tsis kam thiab lub zog.

Lub ntsiab	Inconel 690	Inconel 706
Npib tsib caug (ni)	~58-63%	~41-45%
Chromium (cr)	~27-31%	~15-17%
Hlau (FE)	~7-11%	~28-33%
Cobalt (CO)	Tsawg dua los yog sib npaug rau 0.5%	Tsawg dua los yog sib npaug rau 1.0%
Molybdenum (mo)	Tsawg dua los yog sib npaug rau 0.5%	Tsawg dua los yog sib npaug rau 0.2%
Titanium (ti)	~0.2-0.6%	~1.5-2.0%
Aluminium (AL)	~0.1-0.5%	~0.7-1.2%
Niobium (nb)	-	~2.5-3.0%

Inconel 690: Tus cwj pwm los ntawmCov Ntsiab Lus Chromium Cov Ntsiab Lus(27-31%). Cov theem siab siab no cov ua yeeb yaj kiab chomium dense oxide (croo₃) zaj duab xis nyob rau saum npoo, muab kev tiv thaiv zoo heev rau oxidation thiab corrosion.

Inconel 706: Muaj qis cr tab sis qib siab FE FEX. Nws tso siab rau ti, al, thiab nb vim tus yuam sij ntxiv dag zog rau cov ntsiab lus, uas ua rau muaj kev kho mob los nag thaum ua kom sov.

2. Cov Khoom Siv Neeg Kho Tshuab

Lawv cov cwj pwm kev coj sib txawv sib txawv ntawm kev sib txawv ntawm cov qauv tsim {{} inconel 690 ua ntej corrosion tsis kam, thaum Inconel 706 tsom rau lub zog siab.

Ntiag tug	Inconel 690 (anealed)	Inconel 706 (Hnub Nyoog -} tawv)
Lub zog tensile	~ 690 mpa	Tom ntej 1200 MPa
Paib lub zog	~ 310 MPa	1000 MPa
Elongation	~35%	~15%
Kev nyuaj	~20-25	~38-42

Inconel 690: Feem ntau siv nyob rau hauvannealed xeevCov. Nws muaj lub zog nruab nrab tab sis kev du me me thiab tawv heev, uas pab nqus kev ntxhov siab thaum lub sijhawm ua haujlwm.

Inconel 706: Tiavlub zog siab thiab hardnessLos ntawm kev kho mob hnub nyoog (cov txheej txheem kev kho cua sov uas muaj cov cua sov tshwj xeeb thiab tuav dej nag zoo li yog muaj zog ntxiv dag zog rau theem zoo li '). Nws cov txiaj ntsig lub zog yog dhau 3 zaug uas Annealed Inconel 690.

3. Cov ntawv thov tseem ceeb

Lawv cov khoom sib txawv ua rau lawv haum rau cov khoom lag luam sib txawv.

Inconel 690

Thawj daim ntawv thov: Nuclear zog kev lag luam, tshwj xeeb tshaj yog liChav Generator LeegHauv cov tshuab hluav taws xob cov tshuaj tiv thaiv dej (pwrs).

Qho tseem ceeb: Nws cov ntsiab lus siab muab nws cov kev zam tsis kam musKev ntxhov siab corrosion cracking (SCC)Nyob rau hauv high - kub, siab -}} dej nrog chloride lossis oxygen impurities). Nws tseem tiv thaiv oxidation thaum kub (txog li ~ 800 degree).

Lwm Yam Siv: Cov khoom siv tshuaj lom neeg (piv txwv li, reactors kov cov acids uas xeb) thiab siab- race Cheebtsam.

Inconel 706

Thawj daim ntawv thov: Aerospace thiab roj turbine Industries, xws liTurbine Discs, Shafts, thiab Fasteners.

Qho tseem ceeb: Nws lub zog siab (txawm tias thaum nce qhov kub txog rau ~ 650 degree) thiab zoo nkees ua kom nws zoo rau thauj khoom - bearing} Cov kabmob hauv cov cav. Nws tseem muaj qhov zoo weldability, uas yog qhov tseem ceeb rau kev tsim cov ntu.

Lwm Yam Siv: High {{- Kev ua haujlwm freakeners hauv kev lag luam machinery thiab cov qauv txheej txheem hauv cov roj offshore thiab roj platform.

4. Kev Kho Cua Sov

Ob txoj kev alloys xav tau cov txheej txheem kev kho cua sov sib txawv kom ua tiav lawv cov khoom zoo tshaj plaws.

Inconel 690:

Annaling: Cua sov txog 1050-1150 degree, tuav rau lub sijhawm luv luv, ces dej tso. Cov txheej txheem no tshem tawm sab hauv kev ntxhov siab, restores ductility, thiab stickilizes micrivizes micrivy micrubure.

Tsis tas yuav muaj lub hnub nyoog nyuaj, vim tias nws cov kev ua tau zoo tso siab rau cov teeb meem kev daws teeb meem los ntawm CR thiab NI.

Inconel 706:

Siv annaling: cua sov rau 980-1040 degree, tuav, ces dej tso tseg kom tau txais cov khoom sib txig sib luag.

Hnub nyoog Hardening: Ua kom sov rau 700 -}} 730 degree, tuav rau 16-24 teev, ces cua txias. Cov kauj ruam no precipitates zoo '(ni₃ (ti, al) thiab nb-nplua nuj nce zog thiab hardness.
