Dab tsi cais peb Alloys
5083. Cov ntsiab lus magnesium teev lub zog: 5052 nqa 2.2-2.8%, 5754 nqa 2.6-3.6% thiab 5083 nqa 4.0-4.9%. Cov magnesium siab dua nce lub zog thiab txhim kho kev tiv thaiv dej hiav txwv, tab sis nws kuj ua rau lub qhov rais vuam thiab ua rau muaj kev xav tau yog tias cov khoom raug tuav ntawm qhov kub siab rau lub sijhawm ntev.
Cov ntawv nyias nyias hauv cov qib no raug txiav txim rau ASTM B209 / B209M, uas teev cov ntawv tso cai sib txawv thiab yam khoom siv yam tsawg kawg nkaus rau txhua tus npau taws. Marine phaj nyob rau hauv 5083 yog ntxiv los ntawm ASTM B928. Lub teb chaws sib npaug tshwm sim nyob rau hauv EN 485-2, uas tabulates mechanical zog rau daim ntawv, sawb thiab phaj.

Cov duab qhia yog qhov tseem ceeb rau cov tempers muaj npe, tsis lav qhov tsawg kawg nkaus; kev lees txais yog tawm tsam qhov tsawg kawg nkaus cov khoom tabulated nyob rau hauv cov qauv siv rau daim ntawv txiav txim, temper thiab thickness.
Temper xaiv rau nyias daim ntawv
Temper designations ua raws li EN 515 system. H111 thiab H112 qhia tias muaj kev sib zog me ntsis- hardened lossis raws li -rolled mob thiab yog qhov kev xaiv ib txwm rau cov khoom uas yuav raug tsim hnyav, vim lawv khaws cov ductility tshaj plaws. H22 thiab H32 yog peb lub hlis twg-mob tempers haum rau kev fabrication, vaj huam sib luag ua hauj lwm thiab nres txoj kev. H116 thiab H321 yog stabilized tempers siv nyob rau hauv marine kev pab cuam, qhov twg tsis kam mus rau intergranular nres tom qab ntev raug ntawm qhov kub siab me ntsis teeb meem.
Rau 0.5 hli mus rau 3 hli cov ntaub ntawv, lub temper es lub alloy feem ntau txiav txim seb ib tug khoov yuav tawg. Lub vojvoog khoov nruj nyob rau hauv lub siab tawv tuaj yeem ua tsis tau txawm tias cov hlau nws tus kheej zoo kawg nkaus weldable.
Fabrication thiab Application Notes
Tag nrho peb cov alloys weld zoo los ntawm cov pa roj tungsten arc thiab roj hlau arc txheej txheem siv cov muab tub lim, thiab lawv tau yooj yim txiav los ntawm shear, laser thiab waterjet. Springback nce nrog npau taws, yog li tooling rau H32 lossis H116 daim ntawv yuav tsum tau teem rau lub vojvoog loj dua rau H111. Cov npoo yog muab cov khoom tiav, thiab tuaj yeem txhuam, anodised lossis embossed; anodising ntawm qib siab - qib magnesium ua rau cov xim tsaus dua, cov pob tshab tsawg dua li ntawm 5052.
Cov kev siv ntawm cov ntsuas no suav nrog lub nkoj hull thiab lawj Cheebtsam, tank thiab silo panels, txoj kev thiab kev tsheb ciav hlau lub cev vaj huam sib luag, siab- nkoj sab hauv qhov twg tso cai, thiab cov ntawv dav dav- hlau fabrication qhov hnyav thiab corrosion kuj suav.
Cov lus nug nquag
Q:Qhov twg ntawm peb cov alloys muaj zog tshaj?
A: 5083, vim nws cov ntsiab lus magnesium siab dua thiab manganese ntxiv muab lub zog siab tshaj plaws ntawm peb; 5052 yog qhov qis tshaj plaws thiab 5754 zaum ntawm lawv.
Q:Yam temper yuav tsum xaiv rau nruj khoov?
A: Lub siab mos los yog lub zog me me xws li H111 lossis H112, txij li thaum lub caij nplooj ntoos hlav rov qab thiab tawg tuaj yeem nce ntxiv raws li qhov hnyav nce ntxiv.
Q:5083 puas tuaj yeem siv sab nraum zoov hauv huab cua hauv hiav txwv?
A: Yog, thiab stabilized tempers xws li H116 yog ib txwm teev rau marine lug tiv thaiv intergranular nres.
Q:Cov alloys no puas tuaj yeem kho tau?
A: Tsis yog. Lawv tsis yog -kub- kho tau, yog li lub zog los ntawm kev ua kom tawv nqaij tawv, tsis yog los ntawm kev kho thiab kev laus.
Q:Cov qauv twg siv rau cov ntawv nyias ntawm cov qib no?
A: ASTM B209 / B209M rau daim ntawv thiab phaj, nrog EN 485-2 raws li qhov sib npaug European tabulation ntawm cov khoom siv kho tshuab.
Q:Puas yog anodising ua haujlwm ntawm 5083?
A: Nws ua tau, tab sis cov txheej yog tsaus dua thiab tsis tshua pom tseeb dua ntawm 5052 vim tias cov ntsiab lus magnesium ntau dua.
