Beryllium bronze yog ntau yam nag lossis daus hardening alloy. Tom qab kev daws teeb meem thiab kev laus, lub zog tuaj yeem ncav cuag 1250-1500MPa (1250-1500kg). Nws cov yam ntxwv ntawm kev kho cua sov yog: nws muaj cov yas zoo tom qab kho cov khoom siv thiab tuaj yeem deformed los ntawm kev ua haujlwm txias. Txawm li cas los xij, tom qab kev laus kev kho mob, nws muaj qhov zoo tshaj plaws elastic txwv, thiab nws cov hardness thiab lub zog kuj tseem txhim kho.
(1) Kev daws teeb meem ntawm beryllium bronze
Feem ntau, qhov kub thiab txias rau kev kho mob yog nyob nruab nrab ntawm 780-820 ℃. Rau cov khoom siv los ua cov khoom siv elastic, 760-780 ℃ yog siv, feem ntau los tiv thaiv cov nplej ntxhib los ntawm kev cuam tshuam lub zog. Qhov kub tsis sib xws ntawm kev kho cua sov yuav tsum tau tswj nruj me ntsis hauv ± 5 ° C. Lub sijhawm tuav feem ntau tuaj yeem suav ua 1 teev / 25mm. Thaum beryllium bronze raug rau cov khoom siv hluav taws xob kho cua sov hauv huab cua lossis oxidizing huab cua, oxide zaj duab xis yuav raug tsim rau saum npoo. Txawm hais tias nws muaj kev cuam tshuam me ntsis ntawm cov khoom siv kho tshuab tom qab lub hnub nyoog muaj zog, nws yuav cuam tshuam rau lub neej kev pab cuam ntawm lub cuab yeej pwm thaum ua haujlwm txias. Txhawm rau kom tsis txhob oxidation, nws yuav tsum tau muab tso rau hauv lub tshuab nqus tsev vacuum los yog ammonia decomposition, inert gas, txo cua sov (xws li hydrogen, carbon monoxide, thiab lwm yam) kom tau txais kev kho cua sov zoo. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau kom txo lub sijhawm hloov pauv (thaum lub sijhawm quenching) kom ntau li ntau tau, txwv tsis pub cov khoom siv kho mob tom qab kev laus yuav raug cuam tshuam. Cov ntaub ntawv nyias yuav tsum tsis pub tshaj 3 vib nas this, thiab feem ntau yuav tsum tsis pub tshaj 5 vib nas this. Qhov nruab nrab quenching feem ntau siv dej (tsis xav tau cua sov). Tau kawg, roj kuj tuaj yeem siv rau qhov chaw nrog cov duab nyuaj kom tsis txhob deformation.
(2) Kev laus kho ntawm beryllium bronze
Kev laus kub ntawm beryllium bronze muaj feem xyuam rau cov ntsiab lus Be. Tag nrho cov alloys uas muaj tsawg dua 2.1% yuav tsum muaj hnub nyoog. Rau cov alloys muaj ntau dua 1.7%, qhov zoo tshaj plaws kev laus kub yog 300-330 ° C, thiab lub sij hawm tuav yog 1-3 teev (nyob ntawm seb cov duab thiab thickness ntawm ib feem). Rau cov khoom siv hluav taws xob uas muaj hluav taws xob zoo nrog tsawg dua 0.5%, vim tias qhov kub ntawm qhov kub thiab txias yog 450-480 ° C thiab lub sijhawm tuav yog 1-3 teev. Nyob rau hauv xyoo tas los no, ob-theem thiab ntau theem kev laus kuj tau tsim, uas yog, lub sij hawm luv luv ntawm kev laus ntawm qhov kub thiab txias thiab tom qab lub sij hawm ntev rwb thaiv tsev laus ntawm qhov kub thiab txias. Qhov zoo ntawm qhov no yog qhov kev ua tau zoo dua, tab sis qhov deformation yog txo. Txhawm rau txhim kho qhov tseeb qhov tseeb ntawm beryllium bronze tom qab kev laus, cov khoom siv tuaj yeem siv rau kev laus, thiab qee zaum ob theem ntawm kev laus tuaj yeem siv tau.
(3) Kev kho kev ntxhov siab ntawm beryllium bronze
Kev ntxhov siab kev ntxhov siab annealing kub ntawm beryllium bronze yog 150-200 ℃ thiab lub sijhawm tuav yog 1-1.5 teev. Nws tuaj yeem siv los tshem tawm cov kev ntxhov siab uas tshwm sim los ntawm cov hlau txiav, ncaj, sib sau txias, thiab lwm yam, thiab ua kom ruaj khov ntawm cov duab thiab qhov tseeb ntawm qhov chaw thaum siv mus ntev.
