Isici somkhiqizo
I-GH99 iyingxube ye-Ni-Cr esekelwe emvuleni eyenza lukhuni ukuwohloka kwezinga lokushisa eliphezulu, engasetshenziswa isikhathi eside ngaphansi kuka-900°C, futhi izinga lokushisa eliphezulu lesevisi yesikhathi esifushane lingafinyelela ku-1000°C. Ingxubevange ye-GH99 iqiniswa ukwengezwa kwe-chromium, i-cobalt, i-tungsten ne-molybdenum ukuze kuqiniswe isixazululo esiqinile, ngokwengeza i-aluminium ne-titanium ukuze kwakhiwe izigaba eziqiniswa ukuguga, nangokufaka i-boron, i-cerium ne-magnesium ukuhlanza nokuqinisa imingcele yokusanhlamvu. Ingxubevange ye-GH99 inamandla ashisayo aphakeme, inhlangano ezinzile, futhi inomshini ogculisayo oshisayo nobandayo wokubumba kanye nokusebenza kwenqubo yokushisela.I-GH99 ifanele ukwakhiwa kwamagumbi omlilo wenjini ye-aero-injini kanye namagumbi okushisa uphethiloli kanye nezinye izingxenye zesakhiwo ezishiselwe ezishisa kakhulu. Nge-alloy eyenziwe yisakhiwo esikhulu sepuleti, ingasetshenziswa ngqo ngemuva kwesixazululo esiqinile Ukwelashwa ngaphandle kokuguga Ukwelashwa. Ingxubevange ngo-700 ℃ ~ 950 ℃ ukuguga kwesikhathi eside ayitholanga izigaba eziyingozi.
Isicelo somkhiqizo
I-alloy isetshenziswe ekukhiqizeni igobolondo le-nozzle eliguquguqukayo le-aero-injini, umgqomo wamandla nezinye izingxenye; ibha egoqiwe isetshenziswe ekwenzeni ama-aero-engine compressor blades; i-forged bar isetshenziswe ekwenzeni izinjini ezinkulu zegesi ye-naval kanye nezakhi zesakhiwo semicibisholo ecitshwayo.
