Lub US Naval Research Laboratory tau tsim Haynes alloys thiab muab npe rau lawv tom qab Elbert Haynes kom hwm nws. Txawm hais tias muaj kev thov tsis tu ncua rau siab - kub alloys thaum lub sij hawm lub tebchaws United States 'loj ntau lawm nyob rau hauv WWII, alloys uas tuaj yeem tiv taus qhov kub thiab txias tau ua pov thawj tias tsis tshua muaj heev. Nws yog thaum lub sijhawm cov xwm txheej no uas Haynes alloys tau yug los.
Haynes alloys tau dhau los thiab txuas ntxiv hloov nrog kev nce qib hauv thev naus laus zis thiab nws daim ntawv thov hauv ntau qhov kev lag luam. Tam sim no, Haynes alloys suav nrog siab - cov ntaub ntawv kawg uas muaj ntau yam kev siv.
Yam khoom
Muaj ntau ntau yam ntawm Haynes alloys. Nov yog qee qhov piv txwv ntau dua:
Haynes 230 zoo li yog hom nickel superalloy nrov tshaj plaws. Cov nickel superalloy no suav nrog 20% chromium, 14% molybdenum, 5% tungsten, thiab 0.15% carbon. Qhov tshwj xeeb superalloy no feem ntau yog siv rau hauv cov khoom lag luam rau aviation, aerospace, thiab lub zog sectors vim nws siab - xaj cov qauv welded thiab oxidation - muaj peev xwm tiv taus, nrog rau siab - qhov kub thiab txias.
Haynes 188 kuj tseem muaj npe nrov rau nws qhov siab - qhov kub thiab txias. Haynes 188 kuj yog npib tsib xee-raws li superalloy thiab muaj 22% chromium, 14% titanium, 3% aluminium, thiab 1.5% molybdenum. Cov nickel superalloy no kuj tau ua pov thawj kom dhau Haynes 230 hauv oxidation tsis kam thiab siv rau hauv cov turbines thiab lwm yam khoom siv qib siab.
Haynes 25 kuj yog npib tsib xee-raws li superalloy thiab tso nyiaj rau 20% chromium, 10% molybdenum, 5% tungsten, thiab 3% titanium. Qhov no Haynes alloy, nrog rau superalloy npib tsib xee, tau ua pov thawj kom tshaj thiab tuav lub zog siab, siab - kub lub zog, corrosion kuj, thiab machinability. Cov hlau no kuj tseem siv rau lwm cov ntaub ntawv uas xav tau siab - cov khoom kub thiab cov tshuab.
Lwm yam ntawm Haynes alloy muaj xws li Haynes 214, Haynes 242, Haynes 263, thiab Haynes 282.
Daim ntawv thov
Haynes alloys nquag ua haujlwm hauv ntau qhov kev lag luam, ntau yam uas siv lawv cov yam ntxwv tsis sib xws. Hauv qab no yog ob peb yam ntawm lawv cov kev siv rau ib sector.
Aerospace: Alloys yog qhov tseem ceeb hauv aerospace xws li turbine blades, engine nozzles, thiab gas turbines, uas yog ib co ntawm cov high -kub aerospace Cheebtsam.
Petrochemical: Kev lag luam petrochemical rov siv cov Haynes alloys hauv cov tshuaj reactors, cov khoom siv kho kom zoo, thiab hauv siab - cov kav dej kub uas tiv taus huab cua kub thiab siab, nrog rau xa cov corrosion kuj.
Nuclear: Alloys yog siv rau hauv kev lag luam nuclear rau kev ua haujlwm ruaj khov thiab nyab xeeb ntawm nuclear reactors thiab tsim cov roj cov ntsiab lus, cov khoom siv hluav taws xob, thiab cov kav dej.
Kev Kho Mob: Haynes alloys yog siv rau hauv kev kho mob implants xws li casts thiab dag pob qij txha vim lawv siab biocompatibility.
