Nyob rau hauv qhov siab - qhov kub thiab txias hauv cheeb tsam ntawm cov roj turbine, cov khoom xws li cov khoom siv hluav taws xob sib txuas, cov ntaub thaiv hluav taws xob, thiab cov kav dej tso pa tawm ntsib cov huab cua hnyav. Rau engineers thiab procurement managers, lub ntsiab mob point yog nyob rau hauv qhov kev pheej hmoo ntawm cov khoom tsis ua hauj lwm:
Thermal creep deformation:Ntawm qhov kub thiab txias ntawm650℃rau 700 degree, txheem alloys tuaj yeem soften thiab warp, ua rau kev cuam tshuam kev sib dhos thiab kev ua haujlwm tsis ua haujlwm.
Scale:Cov ntaub ntawv tsis zoo tuaj yeem tsim cov nkig, yooj yim flaking oxide txheej ( nplai), uas ua rau muaj kev puas tsuaj rau hauv qab dej siab - ceev turbine hniav.
Lwm txoj kev ua raws li:Siv "kev lag luam- qib" cov ntaub ntawv uas tsis ua raws li kev nruj aerospace- cov qauv ntawv pov thawj qib.
PebGH4169 (sib npaug rau Inconel 718) ntawv hlau, tshwj xeeb tsim los siv aVIM + VAR (ob lub tshuab nqus tsev melting) txheej txheem, tshem tawm cov kev pheej hmoo no, ua kom muaj kev ncaj ncees ntawm koj lub zog infrastructure.
