Lawv coercivity qis kuj ua rau poob qis. Lub superconductivity ntawm amorphous hlau nyias zaj duab xis tau pom nyob rau hauv thaum ntxov 1950s los ntawm Buckel thiab Hilsch.
Amorphous hlau ua li cas?
Amorphous hlau yog tsim los ntawm kev poob siab khov ntawm cov hlau nplaumCov atoms tsis muaj sijhawm los tsim cov iav crystalline thiab ua kom muaj kev sib haum xeeb (amorphous). Txij li cov theem hloov ntawm cov kua mus rau cov khoom yog suppressed nyob rau hauv cov txheej txheem no, tsis muaj crystallization nuclei yog tsim thaum solidification.
Vim li cas thiaj nyuaj ua amorphous hlau?
Vim tias tsis muaj cov dav hlau ntawm atoms hauv cov khoom siv amorphous, cov atoms yog gridlocked rau hauv cov qauv iav, ua rau kev txav ntawm pawg ntawm atoms nyuaj heev. Ib qho txiaj ntsig ntawm qhov no atomic gridlock, yog tias qee cov hlau amorphous nyuaj heev. Liquidmetal® yog ntau dua ob zaug nyuaj dua stainless hlau.
Thaum twg yog kua hlau tsim?
Atakan Peker ntawm Liquidmetal Technologies, Lake Forest, Calif. Peker ntxiv tau pab Johnson tsim lub tswv yim ntawm kev tsim cov kua hlau tuab uas tsim iav yam tsis tas yuav tsum tau ua kom txias sai. Johnson tau pib ua haujlwm hauv thaj chaw thaum ntxov 1980s nrog cov npoj yaig ntawm NASA's Jet Propulsion Laboratory.
Puas yog hlau amorphous?
Ib yam amorphous hlau yog an alloy ntawm hlau nrog boron thiab silicon Amorphous hlau los ntawm cov neeg muab khoom no hauv daim ntawv nyias (25-microns tuab) ribbon lossis ntawv ci. Daim ntawv no tshwm sim ncaj qha los ntawm cov txheej txheem siv los tsim cov hlau: Molten hlau drips mus rau lub log uas muaj cov ntshiab molybdenum.
