Monel 400 thiab K500 Alloy

1. Tshuaj lom neeg sib xyaw

Cov tub ntxhais sib txawv nyob hauv kev sib ntxiv ntawmntxiv dag zog rau cov ntsiabnyob rau hauv K500, uas Monel 400 tsis muaj. Qhov no cuam tshuam rau lawv cov khoom tom qab.

Hlau	Cov Cheebtsam Tseem Ceeb (raug, los ntawm qhov hnyav)	Qhov tseem ceeb sib txawv
Monel 400	Nickel (NI): 63% - 70%, Tooj (CU): Tsawg dua lossis sib npaug lossis sib npaug: tsawg dua lossis sib npaug nrog 0.5%	Tsis muaj ntxiv dag zog rau cov ntsiab (piv txwv li, al, ti)
Monel K500	Npib tsib (NI): 63% - 70%, tooj (Cu): tsawg dua lossis sib npaug (MN): tsawg dua lossis sib npaug rau 1%,Aluminium (AL): 2.3% - 3.1%, Titanium (ti): 0.35% - 0.85%	Muaj al thiab ti rau nag lossis daus tawv tawv

2. Cov Khoom Siv Neeg Kho Tshuab

Vim tias muaj ntawm Al thiab TI, K500 tuaj yeem tsim kho "los ntawm kev kho cua sov, ua rau muaj zog ntau dua li qhov kub- kev kho monel 400}.

Ntiag tug	Monel 400 (annealed xeev)	Monel K500 (Hnub Nyoog -} Lub Xeev Hardened)
Lub zog tensile	~ 483 MPa (70 Ksi)	~ 1103 mpa (160 ksi)
Tawm Zog (0.2% offset)	~ 172 MPA (25 KSI)	~ 965 MPa (140 Ksi)
Elongation (hauv 50 hli)	~40%	~15%
Hardness (Rockwell B)	~70	~ 110 (Rockwell C: ~ 30)

Monel 400: Mos thiab ductile nyob rau hauv lub xeev annealed; Nws lub zog tsis tuaj yeem txhim kho los ntawm kev kho cua sov (tsuas yog ua haujlwm txias tuaj yeem ua haujlwm me ntsis, tab sis ntawm tus nqi ntawm ductility).

Monel K500: Tom qab "kev daws annealing + hnub nyoog hardening" (cov cua sov kom haum, Al thiab Ti form ua kom zoo heev (ni₃ti) kom zoo heev txhawb zog thiab hardness.

3. Corrosion Kuj

Ob alloys Excel hauv corrosion tsis kam, tab sis lawv cov kev ua tau txawv me ntsis nyob rau hauv ib puag ncig tshwj xeeb:

Muaj zog: Ob qho tiv thaiv corrosion los ntawm seawater, ntsev cov kua, dilute acid (dilrochloric acid (aerated, qis acciic acids. Lawv kuj tsis txhob muaj kev ntxhov siab corrosion (SCC) feem ntau cov tub rog ib puag ncig.

Qhov sib txawv:

Monel 400 tau zoo tsis kam mus rauHydrofluoric acid (HF)thiabCast -} ntws seawater(Vim nws cov ntsiab lus ntau dua Cu cov ntsiab lus thiab qis dua kev pheej hmoo ntawm precipitate -}} induced encomposion corrosion).

Monel K500 tswj hwm zoo corrosion tsis kam tab sis tej zaum yuav tsis muaj kev tiv thaiv me me (piv txwv li nws cov neeg muaj txiaj ntsig, tuaj yeem tsim micro {4} galvanic hlwb nyob rau hauv huab cua.

4. Kev Kho Cua Sov

Qhov no yog qhov kev sib txawv ntawm ob lub alloys:

Monel 400: Cais raws li atsis -} kub -}} kho tau alloyCov. Kev Kho Mob tsuas yog pab rau "Anneal" (muag) cov khoom siv tom qab ua haujlwm txias (piv txwv li kom rov ua haujlwm txias), tsis nce lub zog.

Monel K500: Cais raws li aNas Hau Zog - hatening alloyCov. Nws tso siab rau kev kho cua sov (tov annealing + hnub nyoog hardening) kom ua tiav nws siab- lub zog muaj zog. Yog tsis muaj hnub nyoog tawv, nws cov yam ntxwv zoo ib yam li Monel 400.

5. Thov cov xwm txheej

Lawv qhov sib txawv hauv lub zog thiab corrosion tsis kam ua rau kev siv cov rooj plaub:

Monel 400: Haum rau cov ntawv thov uas nyob qhov twgductility thiab corrosion tsis kamyog ua ntej dhau lub zog siab.

Piv txwv: cov dej hiav txwv seaces, cov twj tso kua mis, tshuaj lom neeg tshuaj ntxuav kom sov (pab roj / roj av / roj av siab} {1} kub siab).

Monel K500: Zoo tagnrho rau cov ntawv thov uas xav tauob lub zog siab thiab corrosion tsis kam.

Piv txwv: tob {- cov khoom siv nuv ntses (piv txwv li lub taub hau roj (piv txwv li}}}} kub corrosion tsis kam).

6. Nqi thiab tshuab luam ntawv

Tus nqi: Monel K500 yog kim dua Monel 400. Qhov ntxiv ntawm Al / TI thiab txheej txheem kev kho mob kub ntxiv (hnub nyoog hardening) nce ntau lawm cov nqi ntau lawm.

Luam ntawv:

Monel 400: Yooj yim rau siv lub xeev annealed xeev (tsawg hardness, zoo nti tsim).

Monel K500: nyuaj rau lub tshuab nyob rau hauv lub hnub nyoog nyob rau hauv lub hnub nyoog - Hardening Lub Xeev (Hardness Hardness, Ultrasive precipitates). Nws yog feem ntau yog machined nyob rau hauv kev daws - Annealed (muag) Lub xeev ua ntej, ces cua sov- {}}} {}} {}}} {}}} {}}}} {}} {}}} {}} {}} {}}}} {}} {} nrhiav kom ua tiav lub zog kawg.
