Hlau yog cov hlau ntshiab. Nov yog cov lus piav qhia ntxaws:
Txhais thiab Cov Khoom
Txhais: Hlau yog cov khoom siv tshuaj nrog lub cim Fe thiab atomic naj npawb 26. Nws belongs rau qeb ntawm cov hlau hloov pauv.
Cov khoom: Cov hlau ntshiab yog hlau dawb los yog silvery-dawb nrog ib tug hlau 光泽. Nws muaj qhov melting point ntawm 1538 degree thiab qhov kub ntawm 2750 degree. Nws yog malleable thiab ductile, txhais tau tias nws tuaj yeem ua tau yooj yim zoo li thiab kos rau hauv cov xov hlau nyias. Cov hlau ntshiab kuj tseem yog mos thiab yooj yim rau kev ua, tab sis nws muaj qis hardness thiab lub zog piv rau qee qhov ntawm nws cov alloys.
Siv dav
Vim nws cov ductility zoo heev thiab malleability, cov hlau ntshiab tau siv dav hauv ntau daim ntawv thov thoob plaws hauv keeb kwm, xws li hauv kev tsim cov cuab yeej, riam phom, thiab tsis ntev los no, hauv kev tsim cov khoom siv hluav taws xob xws li lub tshuab hluav taws xob thiab lub cev muaj zog. Tsis tas li ntawd, hlau thiab nws cov tebchaw yog siv los tsim cov hlau nplaum, tshuaj, inks, pigments, abrasives, thiab lwm yam khoom.
Distinction los ntawm Steel
Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm cov hlau los ntawm cov hlau, uas yog cov hlau alloy nrog carbon thiab lwm yam khoom. Cov hlau muaj qhov nyuaj dua thiab lub zog ntau dua li cov hlau ntshiab vim qhov sib ntxiv ntawm cov hlau alloying, ua rau nws haum rau ntau yam kev siv.
Hauv cov ntsiab lus, hlau yog cov hlau ntshiab uas muaj lub cev sib txawv thiab siv ntau yam. Nws qhov tseem ceeb hauv kev lag luam thiab kev siv thev naus laus zis tsis tuaj yeem hais dhau los.
