Cov yam ntxwv ntawm hluav taws xob resistivity ntawm hluav taws xob cua sov alloy resistivity tseem ruaj khov thaum lub sij hawm kev pab cuam lub neej:

Cov yam ntxwv ntawm hluav taws xob resistivity ntawm hluav taws xob cua sov alloy resistivity tseem ruaj khov thaum lub sij hawm kev pab cuam lub neej:

Lub resistivity ntawm lub cua sov caij yuav tsum nyob ruaj khov thaum siv. Qhov kev hloov pauv me me yog, qhov me dua qhov kev hloov pauv ntawm lub caij thiab qhov hloov ntawm lub zog hluav taws xob rau cov cua sov kuj yog me me, yog li ua kom muaj cua sov zoo thiab ruaj khov.

Hluav taws xob cua sov alloys yuav ua rau muaj kev hloov pauv ntawm kev tiv thaiv vim muaj kev hloov pauv ntawm cov tshuaj lom neeg muaj pes tsawg leeg thiab nag lossis daus ntawm cov tebchaw raws li cov ciam teb lossis hauv cov nplej ntawm qhov kub thiab txias. Nickel-chromium thiab nickel-chromium-hlau alloys yog qhov ruaj khov nyob rau hauv metallographic qauv ntawm qhov kub thiab txias, yog li cov resistivity ruaj khov thaum siv mus ntev. Ntawm qhov tsis sib xws, kev ruaj ntseg ntawm cov hlau-chromium-aluminium alloys yog qhov tsis zoo, feem ntau vim tias cov ntsiab lus txhuas hauv cov hlau tsis tshua muaj zuj zus, ua rau muaj kev hloov pauv hauv kev tiv thaiv.

Cov yam ntxwv ntawm hluav taws xob resistivity ntawm hluav taws xob cua sov alloys High resistivity nqi:

Hluav taws xob cua sov alloy cov ntaub ntawv yuav tsum xub muaj ib tug kuj siab resistivity. Lub tshuab hluav taws xob cua sov ua los ntawm cov khoom siv hluav taws xob muaj zog muaj kev hloov pauv hluav taws xob siab; qhov ntim ntawm cov hluav taws xob cua sov yog me me; cov khoom siv alloy raug cawm; high-power ceev cua sov tuaj yeem pom tau. Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum tsim hluav taws xob cua sov rau hluav taws xob nrog qhov kub thiab txias, lub zog siab thiab qhov me me.

Thaum tsim hluav taws xob cua sov cov ntsiab lus, nyob rau hauv txoj cai, high-temperature Cheebtsam yuav tsum tau ua los ntawm cov ntaub ntawv alloy nrog siab resistivity, thiab low-temperature Cheebtsam yuav tsum tau ua los ntawm cov ntaub ntawv alloy nrog qis resistivity.
