Dab tsi yog Amorphous Sawb?

Cia peb pib nrog cov khoom siv amorphous. Feem ntau muaj ob hom khoom siv uas tib neeg tuaj yeem ntsib hauv lub neej niaj hnub: ib qho yog cov ntaub ntawv crystalline, thiab lwm yam yog cov khoom siv amorphous. Cov khoom hu ua crystalline yog hais txog kev npaj ntawm atoms hauv cov khoom raws li qee cov cai. Ntawm qhov tsis sib xws, yog tias qhov kev npaj atomic sab hauv yog nyob rau hauv lub xeev tsis xwm yeem, nws yog cov khoom siv amorphous. Feem ntau, cov hlau uas muaj kev sib koom ua ke hauv atomic yog cov khoom siv crystalline. Cov kws tshawb fawb tau pom tias tom qab melting, cov atoms sab hauv ntawm cov hlau yog nyob rau hauv ib tug active lub xeev. Thaum cov hlau pib txias, cov atoms yuav maj mam thiab ua kom zoo raws li cov qauv siv lead ua lub xeev raws li qhov kub thiab txias, tsim cov muaju. Yog tias cov txheej txheem cua txias ceev ceev thiab cov atoms khov kho ua ntej lawv tuaj yeem hloov kho, amorphous alloys raug tsim. Cov txheej txheem siv los npaj amorphous alloys yog txheej txheem ceev ceev. Txau qhov kub-kub molten steel rau hauv lub siab ceev rotating txias cov menyuam. Cov hlau txias sai sai ntawm tus nqi ntawm lab tus degrees ib ob, txo qhov kub ntawm 1300 degree steel kom qis dua 200 degree hauv ib txhiab ntawm ib thib ob, tsim amorphous strips.
