Rau technical procurement neeg ua hauj lwm thiab metallurgical kws txawj, kev ntseeg ntawmGH4169 superalloytsis yog tsuas yog kev lag luam thov, tab sis qhov teeb meem ntawm qhov tseeb ntawm qhov sib npaug. Qhov kev sib tw tseem ceeb tshaj plaws hauv kev yuav khoom yog ua kom ntseeg tau cov ntsiab lus niobium (Nb) nyob rau hauv "kub ntau" ntawm 4.75% txog 5.50%.
Qhov tseem ceeb ntawm Niobium:
Niobium yog lub hauv paus tseem ceeb ua rau 'theem ntxiv dag zog.
Kev sib txawv me me hauv Nb cov ntsiab lus tuaj yeem ua rau:
Aging Failure:Nb cov ntsiab lus tsis txaus ua rau txo qis hardness thiab creep zog.
Vuam Risks:GH4169 muaj npe nrov rau nws cov lus teb qeeb qeeb, ua rau nws yooj yim rau vuam yam tsis muaj qhov tawg. Cov cuab yeej tshwj xeeb no nyob ntawm kev tswj hwm ntawm Nb cov ntsiab lus.
