Pure hlau yog malleable.
Malleability yog hais txog cov khoom muaj peev xwm ua rau hammered, nias, lossis dov rau hauv cov ntawv nyias yam tsis muaj kev tawg lossis tawg. Cov hlau ntshiab muaj cov cuab yeej no vim nws cov qauv hlau thiab cov khoom tsis muaj zog ntawm nws cov atoms, uas tso cai rau nws mus rau qhov tseem ceeb deformation yam tsis poob nws txoj kev ncaj ncees.
Nov yog qee cov ntsiab lus tseem ceeb hais txog cov hlau ntshiab lub malleability:
Hlau Bonding: Cov hlau ntshiab muaj cov qauv siv lead ua hlau, uas cov atoms tuav ua ke los ntawm cov hlau nplaum. Cov ntawv cog lus no kuj tsis muaj zog piv rau covalent lossis ionic bonds, tso cai rau cov atoms swb dhau ib leeg thaum raug rau sab nraud. Qhov no ua rau cov hlau ntshiab malleable thiab ductile.
Yas Deformation: Thaum cov hlau ntshiab yog raug compressive los yog tensile rog, nws undergoes yas deformation. Qhov no txhais tau hais tias cov duab ntawm cov khoom hloov mus tas li yam tsis muaj kev tawg lossis tawg. Qhov kev muaj peev xwm ua rau cov yas deformation yam tsis muaj qhov tsis ua haujlwm yog qhov cim ntawm cov khoom siv tau yooj yim.
Kev ua thiab kev siv: Vim nws txoj kev ua tau zoo, cov hlau ntshiab tuaj yeem ua tau yooj yim zoo li tus thiab tsim rau hauv ntau yam duab thiab ntau thiab tsawg siv cov tswv yim xws li hammering, dov, thiab nias. Qhov no ua rau nws muaj ntau yam khoom siv rau ntau yam kev siv, suav nrog kev tsim cov cuab yeej, tshuab, thiab cov khoom siv.
Kev sib piv nrog lwm cov hlau: Txawm hais tias muaj ntau cov hlau yog malleable, cov degree ntawm malleability yuav txawv nyob ntawm seb cov hlau muaj pes tsawg leeg thiab cov qauv. Cov hlau ntshiab, nrog nws cov kev sib txuas ntawm cov hlau tshwj xeeb thiab cov qauv siv lead ua, nthuav tawm cov qib siab ntawm malleability piv rau lwm cov hlau.
Nyob rau hauv cov ntsiab lus, cov hlau ntshiab yog qhov tseeb malleable, thiab cov cuab yeej no ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv hauv ntau yam lag luam.
