Ib, Kev kho cua sov ntawm Inconel 601
Kev kho cua sov txheem rau Inconel 601 (UNS N06601, Werkstoff Nr. 2.4851) yog kev daws teeb meem annealing, uas yog ua rau:
Dissolve tej theem precipitated (xws li, carbides) rov qab rau hauv matrix
Ua ib qho zoo sib xws, zoo -grained microstructure
Ua kom zoo siab -kub lub zog, nkag siab, thiab oxidation kuj
Ib qho kev coj ua yog raws li hauv qab no:
Kub: 1150-1200 ° C (2100-2190 ° F)
Tuav lub sij hawm: 15-60 feeb (nyob ntawm seb cov thickness thiab lub cub tawg hom)
Txias txoj kev: Dej quenching (WQ) los yog cua txias ceev
Dej quenching yog qhov zoo dua rau cov ntu tuab kom ntseeg tau tias muaj qhov sib xws, tag nrho austenitic microstructure
Cov cua txias tuaj yeem siv rau cov ntu nyias, tab sis dej quenching ntau dua rau kev kho cua sov txheem
Tom qab cov tshuaj annealing, Inconel 601 feem ntau tsis muaj hnub nyoog nyob rau hauv cov qauv siv, vim nws lub zog ntawm qhov kub thiab txias yog feem ntau los ntawm cov khoom- kev daws teeb meem ntxiv thiab tsim cov txheej txheem tiv thaiv oxide (Cr₂O₃ + NiCr₂O₄) thaum lub sijhawm ua haujlwm, es tsis yog nag lossis daus.
Rau cov ntawv thov tshwj xeeb, qee cov neeg siv yuav ua rau muaj kev ntxhov siab- nyem annealing tom qab vuam los yog tsim kom txo qis kev ntxhov siab, tab sis qhov no yog daim ntawv thov- nyob ntawm thiab tsis yog ib feem ntawm cov txheej txheem kev kho cua sov.
2, Hom Kev Xa Khoom ntawm Inconel 601
Inconel 601 feem ntau muab rau hauv kev daws teeb meem -annealed thiab quenched mob, raws li teev nyob rau hauv cov qauv xws li ASTM B168 (daim ntawv, phaj, sawb), ASTM B166 (bars, rods, hlau), ASTM B167 (seamless kav thiab raj), thiab lwm yam.
Cov xwm txheej xa khoom tuaj yeem piav qhia raws li:
Kev kho cua sov: tshuaj annealed ntawm 1150-1200 degree, ua raws li dej quenching
Microstructure: Siab austenitic, nrog rau qhov zoo rau nruab nrab grain loj
Mechanical zog:
Chav nruab nrab- qhov kub thiab txias
Zoo ductility thiab toughness
Zoo heev - kub lub zog thiab oxidation tsis kam mus txog 1100℃(2010℃F)
Rau feem ntau lub hom phiaj engineering, kev daws teeb meem -annealed mob yog tus qauv "raws li{1}}xa" lub xeev, thiab kev kho cua sov ntxiv feem ntau tsis tas yuav tsum tau tshwj tsis yog tau teev tseg rau ib qho kev tsim khoom (xws li, kev ntxhov siab tom qab vuam).
