Lub zog sib piv ntawm "alloy" thiab "stainless hlau" tsis ncaj ncaj vim tias"Alloy" yog qhov dav qeb uas suav nrog cov hlau tsis muaj nws tus kheejCov. Ib qho "alloy" yog cov hlau sib sau ntawm ob lossis ntau dua (ooth-based alloys muaj tsawg kawg yog) thiab ntau zaus lwm cov lus xws li npib tsib xee, molybdenum, molybdenum, lossis manganese.
Lub zog yog nyob ntawm cov hom alloy tshwj xeeb, nws muaj pes tsawg leeg, thiab kev kho cua sov. Ntawm no yog qhov tseem ceeb tshaj plaws:
Stainless hlausib txawv hauv lub zog. Piv txwv li:
Austenitic stainless hlau (piv txwv li, 304, 316) muaj lub zog xob rau hauv tensile (300-600 mpa) tab sis kev du me me.
Martensitic stainless hlau (piv txwv li, 440c) tuaj yeem kho tshav kub kom ua tiav lub zog (txog li 1,700 MPa) tab sis muaj tsawg dua corrosion-resistant.
Lwm Yam Alloys(piv txwv li, nickel-based supallloys zoo li inconel, titanium alloys, lossis aluminium alloys) yuav muaj zog dua li qee cov hlau tsis muaj zog:
Kev kub siab aluminium alloys (piv txwv li, 7075-T6) muaj lub zog tensile ntawm ~ 500 mpa, tshaj ntau dhau ntawm kev ua kom tsis muaj cua sov.
Nickel-based alloys zoo li Inconel 718 tuaj yeem ncav cuag lub zog tensile ntawm 1,400 mpa, surpassing feem ntau stainless hlau.
Titanium alloys (piv txwv li, ti, 4v) muab lub zog tensile ntawm 900-1,100 MPa, muaj zog dua 304 stainless hlau (~ 500 mpa).
Tag: Qee cov alloys muaj zog dua li cov hlau tsis muaj zog, thaum lwm tus tsis muaj zog. Nws nyob ntawm qhov tshwj xeeb alloy thiab qib ua piv.
Yog lawm,Inconel alloys feem ntau muaj zog dua li feem ntau stainless hlau, tshwj xeeb tshaj yog thaum nce kub. Ntawm no yog cov ncauj lus kom ntxaws:
Tsis zooYog tsev neeg ntawm Nickel-based superalloys tsim rau lub zog siab, oxidation tsis kam, thiab ruaj khov nyob rau hauv 1,000 txog 1,000℃/ 1,832℃f). Cov zog tseem ceeb xws li:
Chav-Kub Kub: Feem ntau inconel qib (piv txwv li, inconel 600) muaj tensile zog ntawm 600-8 MPA, tshaj li Austenitic Stainless hlau zoo li 304 (500 MPA) lossis 3150 MPA).
Kev Kub Siab Lub Zog: Inconel khaws lub zog ntawm qhov kub ntawm cov hlau stainless. Piv txwv li, Inconel 718 Kev tswj hwm ~ 80% ntawm nws chav-kub (1,200℃f), thaum 31% ntawm nws lub zog ntawm tib qho kub.
Kev Kho Cua Sov: Alloys zoo li Inconel X-750 tuaj yeem yog nag hajensitic muaj zog tshaj 1,300 MPa, ntau dua li, txawm tias qhov kev cia siab rau qhov siab dua yog qhov zoo dua qub).
Yam muaj: Ob peb hom tshwj xeeb stainless hlau (piv txwv li-high-high-high-high-high-high-high, pH Txawm li cas los xij, lawv tseem tsis muaj qhov muaj peev xwm muaj lub zog ntawm cov huab cua sov heev.
Inconel alloys muab lub zog superior piv txwv rau feem ntau cov hlau, ua rau lawv muaj cov cua sov, thiab cov chaw ua kom sov, thiab cov chaw ua pa taws uas stainless hlau yuav swb.
