Beryllium tooj liab feem ntau muab faib ua: tooj liab, tooj dag, tooj liab;Kev kho cua sov ntawm beryllium tooj liab alloy yog tus yuam sij rau nws cov versatility.Sib txawv ntawm lwm cov tooj liab alloys uas tuaj yeem tsuas yog ntxiv dag zog los ntawm kev ua haujlwm txias, lub zog siab heev, conductivity thiab hardness ntawm tshwj xeeb zoo li beryllium tooj liab yog ua tiav los ntawm ob txheej txheem ntawm kev ua haujlwm txias thiab kev kho cua sov.Cov beryllium tooj liab alloys tuaj yeem ua los ntawm kev kho cua sov.Tsim thiab txhim kho nws cov khoom siv kho tshuab, lwm cov tooj liab alloys tsis muaj qhov zoo dua.
Hom ntawm beryllium tooj liab:

Muaj ntau ntau yam ntawm beryllium tooj liab alloys nyob rau hauv kev ua lag luam tsis ntev los no, cov feem ntau yog liab tooj liab (ntshiab tooj liab): oxygen-dawb tooj liab, phosphorus-ntxiv deoxidized tooj liab;tooj dag (tooj liab-raws li alloy): tin tooj dag, manganese tooj dag, hlau tooj dag;bronze Class: tin bronze, silicon bronze, manganese bronze, zirconium bronze, chrome bronze, chrome zirconium tooj liab, cadmium bronze, beryllium bronze, thiab lwm yam. Kev kho cua sov ntawm beryllium tooj liab alloy yog tsim los ntawm kev kho thiab hnub nyoog hardening.
1. Txoj kev kho annealing

Feem ntau, qhov kub thiab txias ntawm kev kho tshuaj yog nyob nruab nrab ntawm 781-821 ° C.Rau cov khoom siv los ua cov khoom siv elastic, 761-780 ° C yog siv, feem ntau los tiv thaiv cov nplej ntxhib los ntawm kev cuam tshuam lub zog.Cov tshuaj annealing tshav kub txoj kev kho mob yuav tsum ua rau lub cub tawg kub uniformity nruj me ntsis tswj nyob rau hauv ± 5 ℃.Lub sijhawm tuav feem ntau tuaj yeem suav ua 1 teev / 25mm.Thaum beryllium tooj liab raug rau kev kho cua sov hauv huab cua lossis cua oxidizing, ib zaj duab xis oxide yuav tsim rau ntawm qhov chaw.Txawm hais tias nws muaj kev cuam tshuam me ntsis ntawm cov khoom siv kho tshuab tom qab kev laus zog, nws yuav cuam tshuam rau lub neej kev pabcuam ntawm lub cuab yeej thaum ua haujlwm txias.
2. Hnub nyoog hardening kev kho cua sov

Kev laus kub ntawm beryllium tooj liab muaj feem xyuam rau cov ntsiab lus ntawm Be, thiab tag nrho cov alloys uas muaj tsawg dua 2.2% ntawm Be yuav tsum raug rau kev laus.Rau cov alloys uas muaj ntau tshaj 1.7%, qhov zoo tshaj plaws kev laus kub yog 301-331 ° C, thiab lub sij hawm tuav yog 1-3 teev (nyob ntawm seb cov duab thiab thickness ntawm ib feem).High conductivity electrode alloys nrog tsawg dua 0.5%, vim qhov nce ntawm melting point, qhov zoo tshaj plaws kev laus kub yog 450-481 ℃, thiab lub sij hawm tuav yog 1-3 teev.

Nyob rau hauv xyoo tas los no, ob-theem thiab ntau theem kev laus kuj tau tsim, uas yog, kev laus lub sij hawm luv luv ntawm qhov kub siab ua ntej, thiab tom qab ntawd mus ntev thermal aging ntawm qhov kub thiab txias.Qhov zoo ntawm qhov no yog qhov kev ua tau zoo dua qub thiab tus nqi ntawm deformation txo.Txhawm rau txhim kho qhov tseeb qhov tseeb ntawm beryllium tooj liab tom qab kev laus, clamping tuaj yeem siv rau kev laus, thiab qee zaum ob txoj kev kho kev laus tuaj yeem siv tau.

Cov kev kho mob zoo li no muaj txiaj ntsig zoo rau kev txhim kho cov hluav taws xob conductivity thiab hardness ntawm beryllium tooj liab alloy, yog li yooj yim rau kev ua tiav ntawm cov khoom tseem ceeb ntawm beryllium tooj liab alloy thaum ua.
