Lub zog ntawm cov khoom yog txiav txim los ntawm ntau yam, nrog rau nws cov tshuaj muaj pes tsawg leeg, microstructure, thiab kev kho cua sov. Ob qho tag nrho cov hlau thiab hlau tuaj yeem tsim kho kom muaj lub zog muaj zog, ua rau nws nyuaj rau kev tshaj tawm tus yeej tsis tau txiav txim siab txog hom thiab kev siv.
Sib piv zog: Alloys vs. Steel
Thaum nws los txog rau lub zog, ob qho tib si alloys thiab steel muaj lawv qhov zoo. Qee cov alloys, xws li titanium alloys lossis qee cov nickel-based superalloys, tuaj yeem pom qhov tshwj xeeb lub zog-rau-hnyav piv thiab ua tau zoo nyob rau hauv huab cua. Cov ntaub ntawv no feem ntau siv rau hauv aerospace thiab kev ua haujlwm siab uas qhov kev txuag hnyav thiab kev ua haujlwm ntev yog qhov tseem ceeb.
Basic Strength ntawm Hlau
Hlau yog cov khoom siv tseem ceeb hauv kev tsim kho thiab kev tsim khoom vim nws lub zog zoo-rau-qhov hnyav piv. Cov pa roj carbon steel, nrog cov ntsiab lus sib txawv ntawm cov pa roj carbon monoxide, muaj qhov zoo tensile zog thiab hardness. Alloy steels, uas suav nrog cov ntsiab lus xws li chromium thiab molybdenum, txhim kho cov khoom xws li toughness thiab hnav tsis kam. Cov hlau no tau siv dav vim tias lawv sib npaug zog, nqi, thiab yooj yim ntawm fabrication.
Alloy Steels: Txhim kho cov khoom
Alloy steels yog npaj los ua haujlwm ntawm cov yam ntxwv tsis meej yav dhau los uas cov hlau tuaj yeem muab tau. Los ntawm kev ntxiv cov khoom xws li npib tsib xee, chromium, lossis vanadium, amalgam npaj tuaj yeem ua kom tiav elasticity dua, zoo dua hardenability, thiab ntxiv kev tiv thaiv los ntawm yaig thiab hnav. Qhov no ua rauIncoloy Alloy 800H bartsim nyog rau cov ntawv thov ntxiv xws li kev kub ntxhov siab lossis kub siab heev.
Incoloy Alloy 800 paub txog nws lub zog ntawm qhov kub thiab txias. Nrog nws cov npib tsib xee-hlau-chromium daim, nws tawm tsam oxidation thiab carburization, ua rau nws zoo tagnrho rau cov khoom siv cua sov thiab siv sib hloov. Qhov kev sib xyaw ua ke no ua rau nws txoj kev sib koom siab thiab kev ruaj ntseg nyob rau hauv cov xwm txheej uas cov txheej txheem npaj tuaj yeem ua tsis ncaj.
Incoloy 800H yog ib qho kev hloov kho ntawm Incoloy 800, npaj rau cov ntawv thov uas xav tau lub zog loj thiab muaj zog. Kev nthuav dav cov pa roj carbon thiab txhuas cov ntsiab lus ntawm 800H txuas ntxiv txhim kho nws cov ductile thiab creep-burst zog, ua rau nws tsim nyog rau cov kev ntxhov siab xws li roj turbines thiab petrochemical tuav.
Rau cov kev thov feem ntau, Incoloy 800HT muaj ntau qhov tseem ceeb tshaj qhov kub thiab txias zog thiab kev tiv thaiv los ntawm creep. Kev sib xyaw ua ke ntawm cov qauv qib siab no lav lub zog thiab kev cia siab rau hauv cov xwm txheej tsis txaus ntseeg, zoo li cov neeg muaj hnub nyoog muaj zog thiab kev siv tshuaj hnyav.
Nws txhais tau hais tias me ntsis yuav tsum nco ntsoov tias lub zog ntawm ob qho tib si sib xyaw thiab hlau tuaj yeem cuam tshuam los ntawm cov txheej txheem kho cua sov, ua haujlwm kom ruaj khov, thiab lwm yam txheej txheem metallurgical. Qhov no txhais tau hais tias lub zog ntawm cov khoom siv tsis yog tag nrho los ntawm nws cov yam ntxwv raws li kev sib xyaw lossis cov hlau tsis tau ntxiv los ntawm qhov nws tau ua thiab kho.
