Kusetshenziswa kabanzi ama-alloys we-titanium emasimini okukhiqiza izimboni ngenxa yesilinganiso sabo esiphakeme esiphakeme esiphakeme, ukumelana nokumelana, kanye nokumelana okuphakeme kokugqwala. Inani elikhulayo lezinkampani likhetha ukusebenzisa i-Titanium Alloy TC11 esikhundleni se-TC4 kubakhiqizi abathuthukisi nama-blades, ngenxa yendawo yokumelana nokuhlangana okungcono kanye nekhono lokusebenza okungcono kakhulu isikhathi eside. I-Titanium Alloys iyizinto ezinzima ze-classical-to-umshini wokuqina okuphezulu okuphezulu okugcinwe emazingeni okushisa aphakeme kanye nokusebenza okuphansi okuholela ekushiseni okuphezulu kokusika. Kwezingxenye ezithile ze-Aero-injini, ezinjengabaphathi abakhulu, ezinezindawo ezisontekile, kunzima ukwanelisa izidingo ezisezingeni eliphakeme neziphakeme kakhulu ngokusebenzisa umsebenzi wokugaya.
Kwinjini yokuhlanza izimoto yangaphakathi, i-turbocharger rotor iba nomthelela ekukhuphukeni kwamandla okusebenza kwamandla kanye nokwehliswa kwamafutha, ngoba igesi yokuphelelwa amandla ikhuthaza ukusebenza kahle kwamafutha. Kodwa-ke, i-turbocharger rotor inomdwebo obulalayo obizwa ngokuthi '' turbo-lag '' okubambezeleka ukusebenza okuqinile kombuso weTurbocharger ngaphansi kuka-2000 RPM. I-Titanium Aluminides inganciphisa isisindo siye esigabeni se-turbocharger evamile. Ngaphandle kwalokho, ama-alloys we-tial anenhlanganisela yobuningi obuphansi, amandla athile athile, izakhiwo ezinhle kakhulu zemishini, nokumelana nokushisa. Ngokuvumelana nalokho, ama-alloys we-tial angasusa inkinga ye-turbo-lag. Kuze kube manje, ukukhiqizwa kweTurbocharger, kufakwe inqubo ye-powder metallurgy kanye nenqubo yokuphosa. Kodwa-ke, kunzima ukusebenzisa inqubo ye-powder metallurgy e-turbocharger ekhiqizweni, ngenxa yokuzwakala kwayo okumpofu kanye nokushiswa.
Ngokombono wenqubo ebiza kakhulu, ukusakazwa kwezimali kungabhekwa njengobuchwepheshe bezomnotho onenzuzo yezomnotho ye-alloys ye-tial. Kodwa-ke, i-turbocharger inezingxenye zodonga ezi-curvature nezingxenye ezincanyana, futhi akukho mininingwane efanele efana nokungasebenzi kanye noketshezi lokushisa lokubumba, lokushisa lokushisa kanye ne-centrifugal Force. Imodeli yokusakaza inikeza indlela enamandla futhi ebiza kakhulu yokutadisha ukusebenza kwamapharamitha ahlukahlukene wokuphonsa.
