Qhov sib txawv tseem ceeb ntawm 5083 H111 thiab 5083 H116 aluminium alloys nyob rau hauv lawv cov txheej txheem tempering, uas ua rau cov khoom sib txawv thiab lawv qhov tsim nyog rau kev siv tshwj xeeb.
5083 H111 yog lub zog uas yog softer thiab ntau formable, ua rau nws haum rau daim ntaub ntawv uas yuav tsum tau ntau dua plasticity thiab yooj yim ntawm shaping. Nws ua haujlwm nruab nrab- hardening tom qab annealing tab sis tsis ua tiav qhov hardness ntawm H11 mob. Qhov kev npau taws no zoo tagnrho rau kev siv dav dav, xws li khoov thiab sib sau, qhov twg lub zog siab tsis yog qhov kev txhawj xeeb tseem ceeb.
Ntawm qhov tod tes, 5083 H116 tshwj xeeb ua tiav los txhim kho nws cov khoom siv kho tshuab, tshwj xeeb tshaj yog nws lub zog thiab corrosion kuj. Nws yog tsim los tiv thaiv exfoliation thiab intergranular corrosion, ua rau nws yog ib qho kev xaiv nrov rau marine daim ntaub ntawv xws li nkoj hulls thiab offshore qauv uas superior corrosion kuj tseem ceeb heev.
Ob lub alloys muaj nyob rau ntawm 5083 series, marine-qib txhuas-magnesium alloy paub txog kev tiv thaiv corrosion zoo thiab weldability. Txawm li cas los xij, lawv lub xeev npau taws (H111 thiab H116) txiav txim siab lawv cov yam ntxwv ua haujlwm:
5083 H111yog ib qho yooj yim ua hauj lwm- hardened tom qab annealing, muab nruab nrab lub zog thiab zoo formability. Nws yog feem ntau siv rau cov qauv siv dav dav uas xav tau lub zog nruab nrab thiab kev ua haujlwm zoo, xws li cov khoom siv welded, automotive panels, thiab tsis yog - cov khoom tseem ceeb marine.
5083 H116yog strain-hardened thiab undergoes ib tug stabilization tshav kub kev kho mob, uas txhim kho nws lub zog, tsis kam mus rau kev nyuaj siab corrosion cracking, thiab corrosion kuj nyob rau hauv hnyav marine ib puag ncig. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev thov cov ntawv thov dej hiav txwv xws li kev tsim khoom nkoj, cov chaw sab nrauv, thiab lwm qhov chaw uas xav tau lub zog siab thiab zoo dua corrosion kuj.
Qhov txawv ntawm 5083 H111 thiab 5083 H116:
Lub zog: H116 muaj zog dua piv rau H111, nrog lub zog tawm los ntawm 230 MPa piv rau 150 MPa rau H111.
Corrosion Resistance: H116 yog optimized rau marine ib puag ncig, muab superior tiv thaiv exfoliation thiab intergranular corrosion.
Ua haujlwm tau: H111 yog ntau formable thiab ductile, thaum H116 muaj zog tab sis yuav tsum tau ceev faj tuav thaum lub sij hawm tsim cov txheej txheem.
Vuam Performance: Ob lub alloys yog weldable, tab sis H116 tau txhim khu kev tiv thaiv rau lub zog hauv zos poob hauv tshav kub- cuam tshuam cheeb tsam thaum vuam, ua rau nws zoo dua rau kev ua haujlwm siab -.
Daim ntawv thov: H111 yog qhov tsim nyog rau cov ntawv thov tsis tshua muaj txiaj ntsig zoo li kev tsim khoom dav dav thiab cov khoom siv, thaum H116 yog qhov zoo tshaj plaws rau siab -load marine thiab offshore qauv uas yuav tsum tau superior corrosion kuj.
Hauv cov ntsiab lus,5083 H111yog tus nqi -tshuaj zoo rau kev siv dav dav nrog lub zog nruab nrab thiab zoo formability, thaum5083 H116yog tsim tshwj xeeb rau marine thiab huab ib puag ncig, muab lub zog ntau dua thiab zoo dua tiv thaiv corrosion thiab kev ntxhov siab tawg.
