Erni {-1 yog cov npib tsib xee yog cov khoom siv tsis zoo (xws li muaj nickel (xws li muaj Nickel 200 thiab 201). Nws tseem dav siv nyob rau hauv kev sib txuas ntawm dissimilar metrals xws li npib tsib xee thiab stainless hlau. Nws cov tshuaj sib xyaw ua ke thiab cov txheej txheem cov yam ntxwv ua rau nws cov khoom siv hluav taws xob tseem ceeb, kev thov ua haujlwm hauv qab no, kev thov ua tau zoo thiab tshawb fawb.
1. Lub ntsiab lus thov cov xwm txheej ntawm Erni -1
Vuam ntawm cov khoom ntshiab npib tsib xee
Ntshiab Nickel (xws li N6 Alloy) tau siv dav hauv cov cuab yeej siv hluav taws xob, hluav taws xob, thiab lwm yam vim nws qhov kev ua tau zoo heev. Txawm li cas los xij, Nickel ntshiab yog nquag mus rau qhov tsis xws luag xws li pores thiab tawg thaum vuam. Erni {{-1 Tseem cuam tshuam tau zoo dua li cov khoom siv tsis zoo (xws li Aroy arc vuam (paw) thiab tungsten inert roj vuam (gtaw).
Kev Sib Txuas Kev Sib Txuas
Erni {-1 yuav siv tau rau vuam npib tsib xee thiab stainless hlau. Piv txwv li, hauv cov cuab yeej siv Nuclear Reactor, cov neeg npib Nickel thoob plaws yog welded nyob rau saum npoo ntawm stainless hlau subtrates (xws li SS316H) txhawm rau txhim kho corrosion tsis kam. Tsis tas li ntawd, nws tseem siv tau los ua cov txheej hloov rau bfe {}}}} composite steel phaj vuam, zoo thaiv cov kev sib txawv ntawm Fe ntsiab thiab ua kom muaj kev ua kom muaj weld.
2. Kev ua tau zoo ntawm erni -1
Deoxidation thiab nitrogen fixation
Lub al (1.5%) thiab ti (2. {{}}. 5%) 5}}}}.
Lis Kev Ua Ntawv Txhim Kho thiab Kev Txhim Kho Cov Khoom Siv
Tin ovrass (yaj taw tes 2950 degree) ua raws li heterogeneous nucleature cores los txhawb nqa cov pas liab ua kom zoo thaum Molten pas crystallization. Qhov nruab nrab nplej loj yog txo los ntawm 125.8 μm ntawm Paw Ua ke rau 54.8 μm, lub zog tensile yog nce los ntawm 11.6%, thiab lub elongation loj hlob ntawm 85.5%. Tsis tas li ntawd, tin muaj peev xwm "Pin" "Austenite gragaries, inhibit Grain Condration, thiab txhim kho creep kam.
Corrosion Kuj Ua Kom Zoo
Hauv 6% kev daws teeb meem, cov xeb corrosion, tus lej ntawm Weld (2.345 G / M²²} that filled than that wel p), tab sis tseem muaj siab dua li ntawm Weld (2.345] yog qhov tsis zoo yog qhov zoo dua li ntawm Weld zoo dua.
3. Cov txheej txheem tswj thiab tshawb fawb txog kev kawm tau
Qhov Tseem Ceeb Ntawm Kev Ua Haujlwm Kev Cai Tswj
Txawm hais tias Al thiab TI muaj cov teebmeem dazidation deoxidation, ntau dhau yuav ua rau muaj ntau qhov loj-suav nrog (xws li 20 μm), uas yuav ua rau muaj kev puas tsuaj ntawm Weld. Cov kev tshawb fawb tau pom tias Ti cov ntsiab lus yuav tsum tau nruj me ntsis tswj tau qhov ntau ntawm 2. 5%}}. 5%}}. 5%}
Vuam cov txheej txheem hloov tau
Erni {-1 yog sib xws nrog ntau hom vuam arc, suav nrog ntshav arc vuam (paw) thiab tungsten inert roj vuam (gtaw). Piv nrog unfilled paw, cov txheej txheem ntsuas hluav taws xob ntau ntawm cov xaim xaim yog dav thiab cov vuam ua kom ruaj khov.
4. Kev lag luam thov kev lag luam
Cov Khoom Siv Hluav Taws Xob Nuclear fais fab: Eni -1 yog siv rau cladding ntawm stadding staytrates los xyuas kom cov kub thiab corrosion reactor nkoj.
Cov Khoom Siv Tshuaj: Hauv vuam ntawm Ntshiab Nickel N6 Reasors, Erni {1}}}}}}}} {}, txuas lub neej ntawm cov khoom siv.
Tag
Erni {-1 vuam hlau ua cov kev cai ntshiab thiab kev xaiv cov kev xaiv zoo tshaj plaws rau qhov kub thiab txias thiab kev txhim kho ib puag ncig. Nyob rau yav tom ntej, nrog lub tshuab hluav taws xob ntawm vuam technical thiab kev tsim kho tshiab ntawm cov khoom tsim qauv, lub peev txheej thov tau ntawm Enti {1} Yuav tau tshaj tawm ntxiv.
