ASTM f2063 yog dab tsi
ASTM f2063 yog dab tsi?
ASTM f2063 yog American Society for Testing and Materials (ASTM) specification for nickel-titanium shape memory alloy npaj rau siv hauv kev kho mob thiab kho hniav.
ASTM F 2063 05 yog dab tsi?
ASTM F 2063 Kev Tswj Xyuas Kev Nyab Xeeb05 hais txog ASTM specification rau nickel-titanium zoo nco alloy siv nyob rau hauv kev kho mob thiab kho hniav daim ntaub ntawv. Cov kev qhia tshwj xeeb qhia txog qhov yuav tsum tau muaj rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev, thiab kev kam rau siab ntawm cov khoom siv nickel-titanium alloy siv hauv kev phais thiab cov khoom siv kho mob.
Dab tsi yog nickel-titanium alloy?
Nickel-titanium alloy, feem ntau hu ua Nitinol, yog cov khoom siv hloov pauv uas siv dav hauv kev lag luam kho mob vim nws cov cim cim xeeb thiab cov khoom siv superelastic. Nitinol yog ib qho kev sib xyaw ntawm nickel thiab titanium, muaj cov txiaj ntsig ntawm ob qho tib si hlau. Cov hlau no yog tus cwj pwm los ntawm nws qhov kev ua tau zoo tshaj plaws, kev nco zoo, thiab kev qaug zog, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev kho mob thiab kev cog hniav.
Dab tsi yog qhov txawv ntawm ntshiab titanium thiab titanium alloy?
Unadulterated titanium yog cov hlau uas muaj cov khoom siv titanium nkaus xwb uas tsis muaj cov hlau sib txawv sib xyaw ua ke. Titanium alloys, ntawm qhov tod tes, yog tsim los ntawm kev sib txuas nrog lwm cov hlau xws li npib tsib xee, txhuas, vanadium, molybdenum, lossis hlau los txhim kho nws cov khoom siv thiab tshuaj lom neeg. khoom. Titanium amalgams yog cov hauv av ntau dua, khoov tau ntau dua, thiab tsis tuaj yeem siv tsis tau ntau dua li cov titanium uas tsis muaj qhov tsis zoo.
Dab tsi yog qhov sib txawv ntawm nickel-titanium alloy?
Nitinol, binary alloy ua los ntawmnickel thiab titanium, thiab Tinel, ternary alloy ua los ntawm npib tsib xee, titanium, thiab hydrogen, yog ob hom nickel-titanium alloys uas tau siv ntau tshaj plaws. Txhua alloy yog tsim los rau ib daim ntawv thov tshwj xeeb thiab muaj cov khoom sib txawv xws li lub cim xeeb zoo, superelasticity, thiab corrosion kuj.
Dab tsi yog qhov txawv ntawm stainless hlau thiab nickel-titanium?
Stainless hlau thiab npib tsib xee-titanium (Nitinol) yog ob qho khoom siv nrov siv hauv kev lag luam kho mob. Stainless hlau yog cov hlau alloy uas muaj hlau, chromium, thiab carbon, thaum Nitinol yog ib qho kev sib xyaw ntawm npib tsib xee thiab titanium. Piv nrog rau cov hlau tsis muaj steel, Nitinol nthuav tawm cov yam ntxwv tshwj xeeb xws li kev nco zoo, superelasticity, thiab biocompatibility, ua rau nws tsim nyog siv rau hauv kev cog qoob loo thiab khoom siv kho mob.
Nickel-titanium hu ua dab tsi?
Nickel-titanium feem ntau hu ua Nitinol. Lub npe Nitinol yog ib lub ntsiab lus muab los ntawm ob lub hlau hauv cov hlau - "Ni" rau nickel thiab "Ti" rau titanium, thiab "NOL" xa mus rau Naval Ordinance Laboratory, qhov twg cov hlau tau tsim thawj zaug.
Hauv kev xaus, cov nickel-titanium alloys tau hloov kho kev lag luam kho mob vim lawv cov khoom tshwj xeeb, xws li cov duab nco thiab superelasticity. ASTM f2063 tus qauv ua kom ntseeg tau tias cov khoom siv nickel-titanium raug tsim thiab sim ua raws li cov qauv tsim nyog thiab kev nyab xeeb.
