Qhov feem pua ntawm tungsten thiab tooj liab nyob hauvtungsten tooj liab alloymuaj kev cuam tshuam loj rau nws cov khoom. Nov yog qee qhov kev cuam tshuam dav dav ntawm qhov sib txawv ntawm qhov feem pua muaj pes tsawg leeg:
Qhov ntom: Ua kom cov ntsiab lus tungsten nyob rau hauv cov hlau ua rau muaj qhov ntom ntom dua. Tungsten muaj qhov ntom ntom dua li tooj liab, yog li qhov feem pua tungsten ntau dua yuav ua rau muaj qhov ntom ntom ntawm cov alloy.
Hluav taws xob conductivity:Cov hluav taws xob conductivity ntawm tungsten tooj liab alloy rods txo qis thaum cov ntsiab lus tungsten nce. Tooj liab yog ib qho zoo heev conductor ntawm hluav taws xob, thaum tungsten muaj qis conductivity. Yog li ntawd, ntau dua tungsten feem pua ua rau txo hluav taws xob conductivity.
Thermal conductivity:Lub thermal conductivity ntawm cov alloy txo nrog nce cov ntsiab lus tungsten. Tooj liab yog ib qho zoo heev thermal conductor, thaum tungsten muaj qis thermal conductivity. Yog li, raws li qhov kev faib ua feem ntawm tungsten nce, thermal conductivity ntawm cov hlau txo qis.
Mechanical Strength: Ua kom cov ntsiab lus tungsten hauv tungsten tooj liab alloy txhim kho nws lub zog txhua yam. Tungsten muaj zog ntau dua tooj liab, yog li qhov feem pua ntawm tungsten ntau dua tuaj yeem ua rau kev txhim kho tag nrho lub zog thiab hardness ntawm cov hlau.
Thermal Expansion: Lub coefficient ntawm thermal expansion txo nrog nce tungsten cov ntsiab lus. Tooj liab muaj cov coefficient siab dua ntawm thermal expansion piv rau tungsten. Yog li ntawd, ntau dua tungsten feem pua ntawm cov hlau ua rau txo qis thermal expansion, ua rau nws ruaj khov dua nyob rau hauv qhov kub thiab txias.
Machineability:Lub machinability ntawm tungsten tooj liab alloy tuav txo nrog nce cov ntsiab lus tungsten. Tungsten yog cov khoom siv tawv dua piv rau tooj liab, ua rau nws nyuaj rau tshuab. Yog li ntawd, alloys nrog ntau dua tungsten feem pua feem ntau nyuaj rau tshuab.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom tshwj xeeb ntawm tungsten tooj liab alloy tuaj yeem sib txawv nyob ntawm qhov feem pua muaj pes tsawg leeg thiab cov ntsiab lus ntxiv alloying tam sim no. Cov khoom sib txawv raug xaiv raws li qhov xav tau sib npaug ntawm cov khoom siv rau kev siv tshwj xeeb, xav txog yam xws li conductivity, lub zog, thermal tswj, thiab machinability yuav tsum tau.
