Dab tsi yog qhov sib txawv ntawm 718 thiab 925 alloy?
Dab tsi yog qhov txawv ntawm alloy 925 thiab Alloy 718?
Nickel alloys
Alloy 925 thiab Alloy 718 muaj ntau yam sib xws. Txawm li cas los xij, vim tias alloy 925 muaj lub zog zoo sib xws rau Alloy 718, nws yog siv tau los ua tus nqi qis dua hauv ntau daim ntawv thov.
Alloy 925 yog ib cocoy npib tsib xee, txhais tau tias qhov loj tshaj plaws hauv nws yog npib loj tshaj plaws nyob rau hauv nws yog npib loj, accounting rau {% ntawm tag nrho. Nws tseem muaj cov hlau, chromium, thiab molybdenum, tab sis nyob rau hauv qis proportions. Hauv kev sib piv, Alloy 718 muaj 50-55}% npib tsib xee, nrog cov nqi sib xws ntawm chromium thiab molybdenum. Vim tias tsib xee yog ib qho kev ntxiv uas muaj nqi ntxiv, qhov nce nyob rau hauv Inconel 718 nce ntxiv los ntawm 20% txheeb ze rau Incoloy rau Incoloy 925.
Cov khoom siv cov khoom siv ntawm Incoloy 925 yog qhov zoo heev li Inconel 718, raws li ob leeg ua tiav lawv lub zog los ntawm nag lossis daus ntau zog. Ib qho ntxiv me me ntawm titanium, txhuas, thiab niobium daim ntawv nplua precipitates thoob plaws cov hlau thaum nws mus dhau los ntawm cov txheej txheem kev kho cua sov theem nrab. Cov precipitates no pab "kho" Micres Microstructure thaum nws raug rau sab nraud thauj khoom, yog li nce nws lub zog thiab tawv.
Gnee pawg cov khoom lag luam thoob plaws 718 hauv cov kab sib txuas los ntawm 5/8 "{{}"} 87-254 mm) hauv lub taub.
Alloy 925 tsis tshua muaj peev xwm yooj yim muaj nyob rau hauv qhov me tshaj diameters, yog li peb cov Tshuag feem ntau pib ntawm 4 "{{{{4 {4 {4} nplej} hli) hauv lub taub.
