FeCrAl AloyiChojambula / Chojambula Chojambula 0.05mm Kukhuthala kwa Magawo Achitsulo a Honeycomb

Zomwe zili ndi aluminiyumu yapamwamba, kuphatikizapo chromium yapamwamba imapangitsa kuti kutentha kwa makulitsidwe kuchuluke mpaka 1425 C (2600F); Pansi pa mutu wotsutsa kutentha, iziFeCrAl aloyis amafananizidwa ndi Fe ndi Ni base alloys omwe amagwiritsidwa ntchito. Monga tikuonera pa tebulo, ndiFeCrAl aloyis ali ndi katundu wapamwamba poyerekeza ndi ma aloyi ena m'madera ambiri.

Dziwani kuti, pakusintha kutentha kwanyengo, kuwonjezera kwa yttrium ku aloyi ya AF, yomwe imadziwikanso kuti Fecralloys alloys, imathandizira kumamatira kwa oxide yoteteza, kupangitsa moyo wautumiki wa zigawo za AF kukhala zotalikirapo kuposa za aloyi. A-1 kalasi.

Fe-Cr-Al alloy mawaya amapangidwa ndi iron chromium aluminium base alloys okhala ndi zinthu zazing'ono zosinthika monga yttrium ndi zirconium ndipo amapangidwa ndi smelting, kugudubuza chitsulo, kupanga, annealing, kujambula, chithandizo chapamwamba, kuyesa kuwongolera kukana, ndi zina zambiri.
Waya wa Fe-Cr-Al udapangidwa ndi makina oziziritsira othamanga kwambiri omwe mphamvu yake imayendetsedwa ndi kompyuta, imapezeka ngati waya ndi riboni(chingwe).

Mbali ndi ubwino
1. Kutentha kwakukulu kogwiritsa ntchito, kutentha kwakukulu kogwiritsa ntchito kumatha kufika 1400C (0Cr21A16Nb, 0Cr27A17Mo2, etc.)
2. Coefficient yotsika ya kutentha ya kukana
3. Kutsika kwamafuta owonjezera kowonjezera kuposa ma Ni-base super-alloys.
4. High resistivity magetsi
5. Kukana bwino kwa dzimbiri pansi pa kutentha kwakukulu, makamaka pansi pa mlengalenga wokhala ndi sulfides
6. Katundu wapamwamba kwambiri
7. Zosamva zouluka
8. Kutsika mtengo waiwisi, Kutsika kochepa komanso mtengo wotsika mtengo poyerekeza ndi waya wa Nichrome.
9. Kukana kwa okosijeni kwapamwamba pa 800-1300ºC
10. Moyo wautali wautumiki

Mapangidwe a metastable aluminiyamu magawo chifukwa makutidwe ndi okosijeni malondaFeCrAl aloyimawaya (0.5 mm makulidwe) pa kutentha zosiyanasiyana ndi nthawi yafufuzidwa. Zitsanzo zinali ndi okosijeni wa isothermally mu mpweya pogwiritsa ntchito thermogravimetric analyzer (TGA). Mapangidwe a zitsanzo zokhala ndi okosijeni adawunikidwa pogwiritsa ntchito Electronic Scanning Electron Microscope (ESEM) ndi X-ray pamwamba pake adagwiritsidwa ntchito pogwiritsa ntchito magetsi a Energy Dispersive X-Ray (EDX). Njira ya X-Ray Diffraction (XRD) idagwiritsidwa ntchito kuwonetsa gawo la kukula kwa oxide. Kafukufuku wonse adawonetsa kuti ndizotheka kukulitsa malo apamwamba kwambiri a gamma alumina paFeCrAl aloyimawaya pamwamba pamene isothermally okosijeni pamwamba 800 ° C kwa maola angapo.
