Ua haujlwm kub siab tshaj plaws (650℃txog 700 degree):Hauv qab no700 degree, lub sij hawm ntev - lub zog ntawm cov alloy pib txo, thiab cov microstructure hloov.
Structural Stability:Lub ntsiab txhawb zog theem ' tseem nyob ruaj khov hauv qab kwv yees li650 degree.
Kev ua tau zoo ntawm GH4169 tshaj qhov ntsuas kub
Cryogenic rau Chav Kub (-253℃txog 20 degree)
Kev ua tau zoo: hwv 4169pom zoo heev toughness thiab lub zog nyob rau hauv cryogenic ib puag ncig, nrog rau cov kua hydrogen(-253 degree) thiab kua nitrogen (-196 degree).
Daim Ntawv Qhia Txog Kev Thov:Cov hlau no tsis pom muaj kev cuam tshuam rau qhov tawg ntawm qhov kub thiab txias, ua rau nws haum rau cov kua - roj foob pob hluav taws.
Qhov kub nruab nrab (20℃txog 600 degree)
Kev ua tau zoo:Cov alloy no tuav lub zog siab thiab ua rau muaj kev qaug zog heev thiab oxidation tsis kam.
Abrasion Resistance:Abrasion kuj nce me ntsis nrog kub (xws li, ntawm 525℃piv rau chav tsev kub).
Kub kub (600℃txog 700 degree)
Lub zog txwv:Saum toj no630 degree, cov khoom pib mos.
Theem Transformation:Ntev raug rau650 degreeua rau "theem (theem muaj zog) hloov mus rau theem ruaj khov (δ theem), yog li txo cov nyhuv ntxiv zog.
Creep Fracture:Zoo heev creep kuj tau pom hauv qab no650℃/ 700 MPa, tab sis qhov no poob sharply ntawm700℃/ 660 MPa.
Extreme Temperatures (>700 degree)
Oxidation:Ntawm850 degree, oxide zaj duab xis nto ua ntxeem tau thiab yooj yim peels tawm.
Kev txwv kev siv:Ntev -lub sij hawm thauj khoom- cov ntawv thov kev coj ua saum toj no700 degreetsis pom zoo raws li cov qauv softening yog ceev.
