Nyob rau hauv 650 ℃, lub alloy muaj siab yield zog thiab rupture zog.Nyob rau hauv 760 ℃, nws muaj oxidation zoo thiab ruaj khov siv mus sij hawm ntev.
Dav siv nyob rau hauv kev tsim cov aviation thiab av roj turbine xyaw ua hauj lwm hauv qab 650C turntable zoo qhov chaw (turbine disc, compressor disc, phau ntawv journal, thiab lwm yam), zoo li qub qauv qhov chaw, turbine txheej nplhaib, fasteners thiab lwm yam.
Incoloy 901 Daim ntawv thov thiab cov kev cai tshwj xeeb:
Qhov no alloy yog dav siv nyob rau hauv aero-engine nyob rau hauv kev ua hauj lwm rotating qhov chaw thiab fasteners ntawm foreian lub teb chaws thiab cov av roj turbine kom txog rau thaum 650 C, ib tug ntev kev pab cuam lub neejHome, nws kuj tau siv nyob rau hauv aircraft engine, uas yog ib tug paub tab alloy los ntawm kev siv xeem. Alloy farging, yog tias cov txheej txheem tsis xaiv lossis kev ua haujlwm tsis raug, nws qhov kev ua tau zoo yuav qhia pom kev ncaj ncees, thiab yuav ua rau muaj qhov sib txawv.tab sis ntev li ntev raws li cov txheej txheem nruj me ntsis, qhov phenomenon.won tsis tshwm sim.Expansion coefficient ntawm cov alloy yog nyob ze rau cov cua sov siv alloy steel, hlau hlau loj uas ua rau nws muaj peev xwm mus txuas ob yam ntaub ntawv nyob rau hauv lub ntsej muag ntawm kub account yam tsis muaj kev tshwj xeeb.
