Ib qho tshuaj tiv thaiv kab mob (APD) yog hom phiaj xwm crystallographic defect nyob rau hauv uas cov atoms nyob rau hauv ib cheeb tsam ntawm ib tug siv lead ua yog configured nyob rau hauv lub opposite kev txiav txim rau cov nyob rau hauv lub zoo meej lattice system. … Hauv lwm lo lus, APD yog ib cheeb tsam tsim los ntawm kev tiv thaiv qhov tsis xws luag ntawm niam txiv lattice.
Dab tsi yog thaj tsam antiphase?
"Tib thaj tsam tiv thaiv" cais ob lub ntsej muag uas nyob ib sab uas muaj tib lub crystallographic orientation tab sis muaj 180 ° theem ua haujlwm (hloov ntawm ib nrab lub sijhawm) ib leeg. Anti-phase ciam teb feem ntau tshwm sim nyob rau theem txiav txim ntawm binary alloy.
Dab tsi yog qhov tsis xws luag yog tus ciam teb antiphase?
Ib tug ciam teb antiphase (APB) cais ob lub npe ntawm tib theem xaj (Marcinkowski, 1963; Kikuchi thiab Cahn, 1979). Nws tshwm sim los ntawm symmetry tawg uas tshwm sim thaum lub sij hawm kev txiav txim, uas tuaj yeem pib ntawm qhov chaw sib txawv hauv cov lattice tsis zoo.
Twin domains yog dab tsi?
Twin domains yog xav tau thaum twg cov qauv muab tau los rau hauv chav kawm qis-symmetry crystal. Antiphase domains tuaj yeem ua tau thaum twg cov qauv muab los tau poob kev ua haujlwm kev txhais lus symmetry. … Twin domains yuav tsum tau txais thaum twg cov qauv muab tau los rau hauv chav kawm qis-symmetry crystal.
Puas yog ntxaib lossis ntxaib?
Raws li nouns qhov txawv ntawm twining thiab twinningis that twining is (countable) ib layout or motionuas twines thaum twinning yog kev ua ntawm cov lus qhia rau ntxaib.
