Cov hlau ntshiab yog hais txog hlau nyob rau hauv nws cov feem ntau cov ntsiab lus thiab unalloyed daim ntawv, nrog ib tug tshuaj cim ntawm Fe thiab ib tug atomic naj npawb ntawm 26. Nws yog ib tug mos, silvery-dawb, ductile, thiab malleable hlau uas muaj ib tug siab hluav taws xob conductivity thiab yog nyiam los ntawm Cov hlau nplaum thaum nyob hauv nws lub xeev ferromagnetic.
Cov hlau ntshiab tsis tshua muaj nyob hauv qhov xwm txheej thiab feem ntau pom muaj nyob rau hauv kev sib xyaw nrog lwm cov ntsiab lus, xws li oxygen, sulfur, thiab carbon, nyob rau hauv daim ntawv ntawm hlau oxides, sulfides, thiab carbonates. Yuav kom tau txais cov hlau ntshiab, cov tebchaw no yuav tsum raug txo kom siv cov txheej txheem xws li smelting, uas yuav tsum tau ua kom sov cov ore nrog ib tug txo tus neeg sawv cev xws li carbon kom tshem tawm cov pa oxygen thiab lwm yam impurities.
Cov hlau ntshiab muaj ntau yam khoom tshwj xeeb uas ua rau nws muaj txiaj ntsig hauv ntau yam kev siv. Piv txwv li, nws lub siab sib nqus permeability ua rau nws zoo tagnrho rau siv nyob rau hauv electromagnetic cores rau transformers thiab lwm yam khoom siv hluav taws xob. Tsis tas li ntawd, nws cov hluav taws xob hluav taws xob siab ua rau nws tsim nyog rau kev siv hluav taws xob thiab lwm yam khoom siv hluav taws xob.
Txawm li cas los xij, cov hlau ntshiab kuj muaj qee qhov kev txwv. Nws yog cov mos mos thiab tsis tshua muaj zog thiab tensile lub zog piv rau lwm yam hlau, xws li hlau, uas yog cov hlau alloy nrog carbon thiab lwm yam khoom. Yog li ntawd, cov hlau ntshiab tsis yog feem ntau siv rau hauv cov qauv siv uas yuav tsum tau muaj zog txhua yam.
Hauv cov ntsiab lus, cov hlau ntshiab yog cov khoom muaj txiaj ntsig nrog ntau yam kev siv hauv ntau yam lag luam, suav nrog hluav taws xob, hluav taws xob, thiab biomedical fields. Txawm li cas los xij, nws txoj kev siv yuav tsum tau ua tib zoo xav txog ntawm nws cov khoom thiab cov kev txwv.
