Ucoceko oluphezulu lweFerro Niobium kwisitokhwe
I-Niobium-iMibandela yeZinto eziNtiya ezinokubakho kwixesha elizayo
I-Niobium yintsimbi engwevu ekhanyayo ngembonakalo emhlophe egudileyo kwimigangatho eqingqiweyo. Ibonakaliswa yindawo ephezulu yokunyibilika yama-2,477 ° C kunye noxinzelelo lwe-8.58G / cm³. I-Niobium inokwenziwa ngokulula, nokuba ngamaqondo obushushu asezantsi. I-Niobium yi-ductile kwaye yenzeka nge-tanttalm kwi-ore yendalo. NjengoTenallom, i-Niobium ikwabonisa ukumelana nokunganyangeki kwekhemikhali kunye ne-oxidation.

Inkcazo:
Eyona nto iphambili kwi-ferniobium yi-iron alloy ye-wiobium nentsimbi. Ikwaqulathe ukungcola ezinjenge-aluminium, i-silicon, ikharbon, nelfure, kunye ne-phosphorus. Ngokutsho komxholo we-Niobium wolwabiwo, yahlulwe yaba yiFenb50, iFenb0 kunye neFenb70. I-iron alloy eveliswe nge-niobium-tantalm ore iqulethe i-tantalelom, ebizwa ngokuba yi-Niobium-Tantalelom iron. I-Ferro-Niobium kunye ne-Niobium-I-Natick Alflis isetyenziswa njengezongezo ze-niobium kwi-vacuum shling yesabelo se-Iron-Alloys. Kuya kufuneka ukuba ube nomxholo wegesi ophantsi kunye nokungcola okuphantsi, anjenge-Pb, SB, BI, i-SNT "njl. Njl. njl.
Isicelo:
I-ferniobium isetyenziselwa ukunyibilikisa ubushushu obuphezulu (ukunganyange ubushushu) isabelo, intsimbi engenasitayile kunye namandla aphezulu ephantsi kwentsimbi. I-Niobium ichaza i-niobium ye-niobium ye-niobium ngekhabhoni kwintsimbi engenasitayile kunye nentsimbi yobushushu. Inokuthintela ukukhula okungqongqo kubushushu obuphakamileyo, hlaziya isakhiwo sentsimbi, kunye nokuphucula amandla, ukuqina kunye neepropathi zensimbi yentsimbi
