Lub ntsiab sib txawv ntawm inconel thiab incoloy -} kev paub

1. Puag Tshuaj Muaj Zog (Cov Tub Ntxhais Tub Ntxhais)

Thawj txoj kab sib faib nyob rau hauv cov txheeb ze sib piv ntawmNickel (NI) thiab Hlau (Fe)- ob lub ntsiab hauv ob lub tsev neeg alloy:

Almoy Tsev Neeg	Nickel (NI) cov ntsiab lus	Hlau (FE) cov ntsiab lus	Qhov Tseem Ceeb Alloying Ntsiab Lus
Tsis zoo	Siab (feem ntau 50-75 wt%)	Tsawg (feem ntau<10 wt%; often a "trace" element)	Chromium (CR, 15-25 WT%) rau oxidation tsis kam; Molybdenum (mo), Niobium (NB), Titanium (ti) (al) rau ntxiv dag zog (ntawm nag lossis daus daus tawv).
Incoloy	Nruab Nrab (Feem Ntau 25-45 WT%)	High (feem ntau ntawm cov lus, ~ 40-60 wt%)	Chromium (CR, 15-25 WT%) rau corrosion tsis kam; Titanium (ti) los yog txhuas (al) (hauv qab qhov qis dua inconel) rau kev ruaj khov, tsis hnyav nag lossis daus tsis txhob muaj nag lossis daus.

Inconel 625: ~ 61% NI, ~ 21% CR, ~ 9% MO,<2.5% Fe.

Incoloy 800: ~ 32% ni, ~ 21% cr, ~ 45% tus nqi ti / al.

2. Cov khoom ntiag tug tseem ceeb

Lawv cov kev sib txawv sib txawv ncaj qha drive divergent kev ua tau zoo, tshwj xeeb hauvhigh - kev coj tus cwj pwm kubthiabHardness / Muaj Zog Txhawb Cov Hluav Taws Xob:

Cov cuab yeej qeb	Tsis zoo	Incoloy
High - lub zog kub	Tshwj. Tsim los rau "creep resistance" (tsis kam rau deformation nyob rau hauv ntev-}}}} kev kub ntxhov (txog li 1,200℃/ 2,192℃f). Ua tiav ntawmnag lossis daus tawv tawv(piv txwv li, gamma - Prime} Prime (') ntu los ntawm Ti / Ib Ntxiv), uas ntsuas phoo), uas ntsuas phoo hloov pauv hauv microstructure.	Zoo, tab sis qis dua li inconel. Zoo rau "Oxidation / Corrosion Kuj" ntawm kev mob siab (txog ~ 870 qib siab (1,600℃f) es tsis muaj zog. Kev txhawb nqa ntxiv los ntawm cov khoom khov kho los ntawm cov tawv- kev daws teeb meem (CR / MO) thiab cov khoom siv tsis muaj dej nag.
Hardness & Ductility	Harder hauv tshav kub -}} {{1} {{1} {{1} {} ag, inconel 718: ~ 35-45-45-45-45-45-45-45-45-45-45-45-45-45-45-45-45-45-45-45-45-45-4m). Ductility yog ib nrab (tshuav nyiaj dag zog).	Softer nyob rau hauv cov annealed yub (piv txwv li, incoloy 800: ~ 140-180 hb / 70-85 hrb). Kev du dua, ua rau nws yooj yim rau daim ntawv (piv txwv li, khoov, vuam) yam tsis muaj kev tawg.

Tsawg dua qhov optimized rau tus nqi -} istosion, generosion scenarios.	Balanced, nqi -}}}}}}Corrosion Kuj(piv txwv li, rau sulfuric acid, seaterwater, muaj chemical) ntawm qhov kub kub. Oxidation tsis kam yog qhov zoo tab sis tsis yog huab li inconel.

3. Cov ntawv thov raug

Lawv cov khoom haum nrog qhov sib txawv siv cov xwm txheej, xav txog lawv cov hom phiaj tsim:

Almoy Tsev Neeg	Cov Ntawv Qhia Tseem Ceeb	Kev ceeb toom
Tsis zoo	- Aerospace: roj turbine li, combusction chambers, dav hlau cav sib xyaw. -} Power Tiam: Boiler Superheater Leeg, Nuclear Refore Qhov Chaw. {-}} {- kub reactors (qhov twg cov cav tov yog qhov tseem ceeb).	Yuav tsum tau tiv thaiv lub sijhawm ntev dhau los ua kom sov (800-1,200℃tsis muaj deficical- nws cov ntsiab lus siab thiab nag lossis daus pab kom qhov no.
Incoloy	- petrochemical: cov pip hluav taws xob, roj hluav taws xob roj (resistions sulfuric acid / crude roj corrosion). {{0- Arine: Seasater Relling Tshuab (Reazing Chloride - induced pitting). {{0- Cov Khoom Noj Ua Khoom Noj: Stainless Hlau {{} Kuv cov ntsiab lus NI qis dua tab sis corrosion tsis kam yog tseem.

4. Tus nqi & Dricabability

Tus nqi: Inconel yog qhov kim dua kim dua li incoloy, vim nws cov ntsiab lus npib tsib txhiab xyoo (npib tsib xee) thiab ntxiv ntawm cov nqi ntau xws li niobium lossis molybdenum.

Qhov xwm txheej: Incoloy yog qhov yooj yim rau weld, thiab tshuab {{{{- nws cov ntsiab lus qis dua txo qis kev pheej hmoo ntawm kev tawg. Inconel, tshwj xeeb tshaj yog nag lossis daus {{2} eg, tsis txhob muaj qhov loj dua vuam (piv txwv li cov tshuab hluav taws kub ntau dua) thiab kev kho kom zoo dua thaum tshav kub kub
