Magnesium, lithium, thiab calcium tsuas yog yaj hauv tooj liab, thiab manganese thiab tooj liab tau sib xyaw ua ke tas li. Plaub yam no tuaj yeem siv tau ua deoxidizers rau tooj liab. Manganese tuaj yeem ua kom muaj zog ntawm tooj liab. Cov tooj liab tooj liab tsawg manganese muaj lub zog siab thiab tiv taus xeb, thiab tau siv hauv kev tsim tshuaj lom neeg. Manganese-tooj liab muaj tsawg heev tiv thaiv qhov kub thiab txias thiab tiv taus cov hlau tsis zoo. Vim yog qhov hloov pauv ntawm allotropic siv lead ua, theem kev hloov pauv ntawm tooj liab-manganese alloy hauv lub xeev ruaj khov yog qhov nyuaj heev. Hauv theem ruaj khov, nws muaj cov txheej txheem ntawm kev hloov pauv hloov pauv hloov pauv thiab hloov pauv hloov pauv. Nws muaj kev vibration thiab suab nrov txo cov khoom thiab yog cov khoom sib xyaw ua kom damping.
Cov khoom ntiaj teb tsis tshua muaj neeg sawv cev los ntawm cerium yuav luag tsis yaj hauv tooj liab. Lawv lub luag haujlwm hauv tooj liab yog hloov kho thiab ua kom huv. Lawv tuaj yeem desulfurize thiab deoxidize, thiab tuaj yeem tsim cov ntsiab lus melting siab nrog cov ntsiab lus qis melting impurities kom tshem tawm cov teeb meem cuam tshuam thiab txhim kho tooj liab thiab cov phom sij. Yas yas, ntxiv cov khoom ntiaj teb uas tsis tshua muaj neeg rau hauv kev kos cov hlau nplaum tuaj yeem txhim kho cov yas thiab txo qhov txias ua haujlwm tawg. Raws li cov ntsiab lus zinc hauv tooj dag nce, cov qauv ntawm chav sov yog li α, α + β, thiab β. The α theem muaj cov yas zoo nyob hauv chav sov, thaum β theem muaj cov yas zoo thaum kub, thiab tsis tuaj yeem tiv taus yas deformation ntawm chav sov.
Raws li cov ntsiab lus zinc nce ntxiv, lub zog ntawm tooj dag nce ntxiv, thiab nws cov yas qis dua, zoo li hluav taws xob thiab cov cua sov ua kom sov. Feem ntau hais lus, qis melting point impurities xws li Pb, Bi, Sb, P, thiab lwm yam yog teeb meem rau tooj dag. Lawv tsim cov khoom sib txuas ua ke nrog tooj liab, uas tau faib rau hauv thaj tsam ntawm cov qoob loo thiab ua rau cov cua sov tawg. Tus qauv yuav tsum tau tswj nruj me ntsis. Feem ntau, nws tsis tas yuav tsum tau ua. Ntau tshaj 0.005%, txhawm rau tshem tawm lawv cov kev phom sij, hloov pauv, xws li zirconium, lub ntiaj teb tsis tshua muaj, thiab lwm yam tuaj yeem muab ntxiv, uas tuaj yeem tsim cov khoom sib xyaw ua kom ruaj khov nrog cov ntsiab lus qis.
Ntau lub ntsiab lus muaj txiaj ntsig zoo rau tooj dag, xws li txhuas, tin, txhuas, hlau, manganese, npib tsib xee, silicon, thiab lwm yam. Lwm cov ntsiab lus tuaj yeem txhim kho lub zog thiab kev tiv thaiv xeb ntawm tooj dag. Lawv lub zog ntawm cov qauv tooj dag muaj qhov sib txawv ntawm kev nthuav dav thaj tsam α theem thiab txo qis area theem cheeb tsam, uas tuaj yeem txiav txim los ntawm zinc sib npaug.
Cov tooj dag tuaj yeem ua tiav los ntawm cov txheej txheem cua sov thiab txias txias. Cov khoom ua tiav siab yog nyob rau hauv daim ntawv ntawm daim hlau, kab xev, raj, pas nrig, xov hlau, thiab lwm yam. Cov txheej txheem tsis ua, txheej txheem txheej txheem thiab cov khoom siv yuav muaj qhov cuam tshuam tseem ceeb rau kev ua tau zoo ntawm cov khoom. Cov khoom siv tooj dag Feem ntau, yuav tsum tau kho kom tsis txhob muaj kev nyuab siab, txwv tsis pub kev nyuab siab yuav tawg thaum siv, tshwj xeeb tshaj yog nyob hauv cov xov xwm corrosive thiab cua.
