Intengo Yefekthri Thengisa I-Niobium Powder nge-Nb kanye ne-CAS No 7440-03-1 Ama-Alloys aphezulu-Entropy(HEA)

i-superalloy

Ingxenye enkulu ye-niobium yomhlaba isetshenziswa ekukhiqizeni i-nickel, i-chromium kanye nama-superalloys asekelwe ku-iron ngendlela ehlanzekile yensimbi noma ngendlela yokuhlanzeka okuphezulu kwe-ferric niobium kanye ne-niobium nickel alloys. Lawa ma-alloys asetshenziswa ezinjinini zejethi, ezinjinini ze-turbine yegesi, ezingxenyeni zamarokhethi, kuma-turbocharger nakumadivaysi omlilo angashi. I-Niobium izokwakha isigaba esingu-y esakhiweni sokusanhlamvu se-superalloy. Lawa ma-alloys ngokuvamile aqukethe i-niobium efika ku-6.5%. I-Incone1718 alloy ingenye ye-niobium-nickel based alloys, okuqukethwe kwe-elementi ngayinye: i-nickel 50%, i-chromium 18.6%, i-iron 18.5%, i-niobium 5%, ukhiye 3.1%, i-titanium 0.9% ne-aluminium 0.4%. Izicelo zifaka okokusebenza kwe-airframe ephezulu, okusetshenziswe ku-Project Gemini.

I-Niobium base alloy

I-C-103 iyingxubevange ye-niobium equkethe u-89% niobium, 10% hafnium kanye no-1% we-titanium, engasetshenziswa kumabhomu okuqhuma amarokhethi e-liquid, njengenjini eyinhloko yemoduli yenyanga ye-Apollo. Imojula yesevisi ye-Apollo isebenzise ingxubevange yesiliva ehlukile. Njengoba i-niobium iqala ukwenza i-oxidize ngaphezu kuka-400 ° C, ukuze ivimbele ukuthi ingabi brittle, kufanele kufakwe i-coating yokuvikela ebusweni bayo.

I-Niobium nayo idlala indima ebalulekile ekwelashweni kokuhlinzwa, ayikwazi ukusetshenziselwa kuphela ukukhiqiza amadivaysi ezokwelapha, kodwa futhi "izinto eziphilayo eziguquguqukayo", ngoba inokumelana nokugqwala okuhle kakhulu, ngeke ihlanganyele nezinto ezahlukahlukene eziwuketshezi emzimbeni womuntu. , futhi cishe azilimazi ngokuphelele izicubu zomzimba webhayoloji, ngoba noma yiziphi izindlela zokuvala inzalo zingajwayela. Ngakho-ke ingabopha izicubu ze-organic isikhathi eside futhi ihlale ingenabungozi emzimbeni.
