Dab tsi yog qhov hardness ntawm tantalum hlau nyob ntawm?
Lub hardness ntawmtantalum hlaufeem ntau yog nyob ntawm nws cov purity thiab nws yuav ua li cas.
Feem ntau hais lus, tantalum xaim nrog ntau dua purity feem ntau tsis muaj zog, thaum tantalum hlau uas tau dhau los ua qee cov txheej txheem tuaj yeem muaj zog dua.
Nov yog qee qhov kwv yees li ntawm tantalum hardness qhov tseem ceeb:
Higher purity tantalum: feem ntau muaj qis hardness, zoo ib yam li hlau los yog txhuas. Hardness tuaj yeem ntsuas ntawm Vickers hardness (HV) nplai, uas yog kwv yees li ntawm 50 HV thiab 200 HV.
Txias ua hauj lwm tantalum: Lub hardness ntawm tantalum tuaj yeem nce ntxiv los ntawm kev ua haujlwm txias xws li dov, kos duab lossis extrusion.
Kev ua haujlwm txias ua rau cov qauv siv lead ua los ze zog, yog li ua kom tawv tawv. Lub hardness ntawm kho tantalum tuaj yeem ncav cuag 300 HV.
Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov hardness ntawm tantalum yog ze ze rau nws cov kev siv thiab tuav. Hauv qee qhov kev siv kub, xws li aerospace lossis nuclear industries, siab dua-hardness tantalum yuav nyiam vim nws tuav lub zog thiab ruaj khov nyob rau hauv high-temperature ib puag ncig.
Txawm li cas los xij, hauv lwm daim ntawv thov, softer tantalum tej zaum yuav tsim nyog dua vim tias nws tuaj yeem ua tau yooj yim dua rau hauv cov duab uas xav tau. Hardness kuj tuaj yeem hloov kho los ntawm alloying thiab kev kho cua sov kom ua tau raws li cov kev xav tau ntawm kev siv sib txawv.
