superalloy

A na-eji akụkụ buru ibu nke niobium nke ụwa na-emepụta nickel, chromium na ígwè superalloys n'ụdị dị ọcha dị ọcha ma ọ bụ n'ụdị ịdị ọcha dị elu ferric niobium na niobium nickel alloys. A na-eji alloys ndị a na igwe jet, injin turbine gas, akụrụngwa roket, turbochargers na ngwaọrụ ọkụ na-eguzogide okpomọkụ. Niobium ga-etolite y phase na nhazi ọka nke superalloy. Alloys ndị a n'ozuzu nwere ihe ruru 6.5% niobium. Incone1718 alloy bụ otu n'ime niobium-nickel alloys, ọdịnaya nke ọ bụla mmewere bụ: nickel 50%, chromium 18.6%, ígwè 18.5%, niobium 5%, igodo 3.1%, titanium 0.9% na aluminum 0,4%.
