Lub uniformity ntawm lub resistivity ntawm lub cua sov raj yog zoo dua:

Lub uniformity ntawm resistivity txhais tau hais tias lub resistivity ib 'meter' thiab batch ntawm hluav taws xob cua sov alloy hlau los yog sawb los yog tus nqi kuj nyob rau hauv ib lub 'meter' yuav tsum zoo ib yam, thiab lub fluctuation ntau npaum li cas yuav tsum tau me me li sai tau. Lub uniformity ntawm resistivity muaj feem xyuam rau ntau yam xws li alloy smelting, casting billet, kev kho cua sov, ib qho hnyav ntawm hlau pas nrig thiab lwm yam.

Lub uniformity ntawm resistivity ntawm nickel-chromium thiab nickel-chromium-hlau alloys yog zoo dua li ntawm cov hlau-chromium-aluminium alloys. Cov txhuas nyob rau hauv lub tom kawg yog nquag mus rau segregation thaum smelting thiab ingot casting (qhov tshwm sim ntawm uneven tis ntawm constituent ntsiab nyob rau hauv lub alloy thaum crystallization) hu ua segregation), uas ua rau ib tug txo nyob rau hauv lub uniformity ntawm lub alloy.

Lub uniformity ntawm resistivity yog tshwj xeeb tshaj yog tseem ceeb rau filaments thiab nyias strips. Vim tias lawv feem ntau yog siv los tsim hluav taws xob cua sov rau cov khoom siv hauv tsev hauv ntau qhov ntau, yog tias qhov tsis sib xws ntawm kev tiv thaiv tsis zoo, lub zog ntawm txhua lub ntsiab lus yuav txawv.
