Kev kub siab ua haujlwm: Turbine hniav yuav tsum tau tiv thaiv qhov cuam tshuam ntawm qhov kub thiab txias cua txias thaum lub cav ua haujlwm. High-temperature alloys muaj zoo heev kub-kub kuj thiab muaj peev xwm tswj cov txheej txheem stability nyob rau hauv huab ua hauj lwm kub thiab tsis yooj yim rau soften, yaj los yog poob.
Lub zog siab thiab tawv tawv: Turbine hniav yuav tsum tau tiv thaiv lub zog loj los ntawm kev sib hloov ceev thiab cov cua kub siab, thiab cov hlau kub kub muaj lub zog zoo thiab nruj, muaj peev xwm tswj tau cov duab ruaj khov nyob rau hauv cov kev ua haujlwm hnyav thiab tsis yooj yim deformed lossis tawg.
Anti-oxidation thiab anti-corrosion zog: High-temperature alloys tuaj yeem tsim cov txheej tiv thaiv oxidation ntom ntom kom tiv thaiv cov pa oxygen hauv cov huab cua los ntawm kev ua rau oxidative corrosion rau cov hniav nto thiab txuas lub neej kev pab cuam ntawm cov hniav.
Thermal fatigue resistance: Turbine blades raug cuam tshuam los ntawm cov thermal cycles thiab thermal expansion thaum lub sij hawm ua hauj lwm, thiab muaj feem xyuam rau thermal qaug zog tawg. High-temperature alloys muaj zoo thermal qaug zog tsis kam thiab muaj peev xwm tswj tau stability nyob rau hauv high-temperature cyclic loads thiab ntev kev pab cuam lub neej ntawm cov hniav.
