Isici somkhiqizo
I-GH907 iyimvula ye-Fe-Ni-Co eyenza lukhuni ukunwebeka okuphansi kwengxube yezinga lokushisa eliphezulu, iqiniswe nge-niobium, i-titanium, i-silicon kanye ne-trace boron. I-alloy inamandla aphezulu, i-coefficient ephansi yokwandisa, ukumelana kahle nokukhathala okushisayo nokubanda kanye ne-modulus ecishe ibe njalo yokunwebeka ngaphansi kuka-650 ℃. Iphoyinti le-Curie liphakathi kuka-400 ℃ no-450 ℃. I-coefficient yokunwetshwa kwe-alloy empeleni ayishintshile ngaphansi kwephoyinti le-Curie. Ingxubevange ilungele ukukhiqizwa kwazo zonke izinhlobo zamasongo enjini yendiza kanye nomagazini ngaphansi kuka-650 ℃, futhi imikhiqizo eyinhloko ihlanganisa imigoqo, ama-forging, amapuleti namapheshana. Ngenxa yokuthi ingxubevange ayinayo i-chromium, izakhi ze-aluminium, ukumelana nokushisa okuphezulu kwe-oxidation akulungile. Uma isetshenziswa isikhathi eside ngaphezu kuka-700 ℃, kufanele kwamukelwe okokuvikela okufanele. Ingaphezulu lengxubevange lingadutshulwa, futhi ukukhathala okugobayo okujikelezayo kungakhuphuka cishe ngo-18% ngemva kokuchama kwesibhamu.
Isicelo somkhiqizo
Ingxubevange isetshenziswe isesimweni esihle ekukhiqizeni omagazini bangemuva be-aero-injini yokucindezela okuphezulu kwe-compressor, izindandatho ezithwala imithwalo, izindandatho ezivikela ukushisa, izindandatho zokuvalwa kwegumbi elivuthayo, izihlalo zekhekheba lezinyosi nezindandatho zangaphandle ze-turbine.
