Ntau npaum li cas yog qhov tsim nyog tshaj plaws quenching hardness ntawm beryllium bronze
Feem ntau hais lus, lub hardness ntawm beryllium bronze yog tsis nruj me ntsis teev, vim hais tias tom qab beryllium bronze solid tov thiab kev laus kev kho mob, nyob rau hauv ib txwm muaj xwm txheej, yuav muaj qeeb nag lossis daus ntawm solidified theem rau lub sij hawm ntev, yog li peb yuav pom tias beryllium bronze nce. nrog lub sijhawm.Qhov tshwm sim uas nws hardness kuj nce nrog lub sij hawm.Tsis tas li ntawd, cov ntsiab lus elastic yog nyias los yog nyias nyias, thiab nws yog ib qho nyuaj rau kev ntsuas qhov hardness, yog li lawv feem ntau yog tswj los ntawm cov txheej txheem yuav tsum tau ua.Hauv qab no yog qee cov ntaub ntawv rau koj siv.

Beryllium bronze kev kho cua sov

Beryllium bronze yog ib qho khoom siv 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 kho cua sov yog: tom qab kev kho cov tshuaj, nws muaj cov yas zoo 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 hardness thiab lub zog kuj tseem txhim kho.

(1) Kev kho mob ntawm beryllium bronze

Feem ntau, qhov kub thiab txias ntawm kev kho mob yog nyob nruab nrab ntawm 780-820 ° C.Rau cov ntaub ntawv siv los ua cov ntsiab lus elastic, 760-780 ° C 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 ℃.Lub sijhawm tuav feem ntau tuaj yeem suav ua 1 teev / 25mm.Thaum lub beryllium bronze raug rau kev kho cua sov hauv huab cua lossis cua oxidizing, ib zaj duab xis oxide yuav raug tsim rau saum npoo.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.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 qhov cua (xws li hydrogen, carbon monoxide, thiab lwm yam), thiaj li yuav tau txais kev kho cua sov zoo.Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau luv luv lub sij hawm hloov mus rau ntau li ntau tau (hauv qhov no ntawm quenching), txwv tsis pub nws yuav cuam tshuam rau cov khoom siv kho tshuab tom qab kev laus.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 muaj cua sov yuav tsum), tau kawg, qhov chaw nrog cov duab nyuaj kuj siv tau roj kom tsis txhob deformation.

(2) Kev laus kev kho mob ntawm beryllium bronze

Kev laus kub ntawm beryllium bronze muaj feem xyuam rau cov ntsiab lus ntawm Be, thiab tag nrho cov alloys uas muaj tsawg dua 2.1% ntawm Be 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).High conductivity electrode alloys nrog tsawg dua 0.5%, vim qhov nce ntawm melting point, qhov zoo tshaj plaws kev laus kub yog 450-480 ℃, 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, tab sis tus nqi ntawm deformation raug txo.Txhawm rau txhim kho qhov tseeb qhov tseeb ntawm beryllium bronze tom qab kev laus, clamping tuaj yeem siv rau kev laus, thiab qee zaum ob txoj kev kho kev laus tuaj yeem siv tau.

(3) Kev kho kev ntxhov siab ntawm beryllium bronze

Beryllium bronze kev nyuaj siab nyem annealing kub yog 150-200 ℃, tuav lub sij hawm yog 1-1.5 teev, uas yuav siv tau los tshem tawm cov residual kev nyuaj siab tshwm sim los ntawm hlau txiav, straightening, txias sib sau, thiab lwm yam. thaum siv mus ntev.

Beryllium bronze yuav tsum tau kho cua sov rau HRC 30 degrees.Yuav tsum kho li cas?
Beryllium tooj liab

Muaj ntau qib, thiab qhov kub ntawm kev laus yog txawv.Kuv tsis yog ib tug kws tsim khoom ntawm beryllium tooj liab, thiab kuv tsis paub txog nws.Kuv tshawb xyuas phau ntawv qhia.

1. Qhov kev daws teeb meem ntawm high-strength beryllium tooj liab yog 760-800 ℃, thiab cov tshuaj kub ntawm high-conductivity beryllium-tooj ​​liab yog 900-955 ℃.Ntu me me thiab nyias yog khaws cia rau 2 feeb, thiab ntu loj yuav tsum tsis pub tshaj 30 feeb.Cov cua kub ceev yog yooj yim thiab ceev.qeeb,

2. Tom qab ntawd nqa tawm quenching, lub sij hawm hloov mus yuav tsum luv luv, thiab qhov txias txias yuav tsum ceev li sai tau kom tsis txhob muaj nag lossis daus ntawm lub zog ntxiv thiab cuam tshuam rau kev laus tom qab kev kho mob ntxiv.

3. Kev laus kev kho mob, kev laus kub ntawm high-strength beryllium tooj liab yog 260-400 ℃, thiab lub tshav kub preservation yog 10-240 feeb, thiab cov laus kub ntawm high-conductivity beryllium tooj liab yog 425-565 ℃, thiab tuav lub sij hawm. yog 30-40 feeb;Nyob rau tib lub sijhawm, tus qub tuaj yeem kho tau, thaum lub sijhawm tom kawg tsis tuaj yeem kho.Nws yog ib qho tsim nyog yuav tau pib dua los ntawm kev daws teeb meem dua.

Lub tempering koj hais yog softening saum cov laus kub, txoj cai?Yog li ntawd, thawj cov khoom siv tshuaj tau raug rhuav tshem.Kuv tsis paub tias qhov kub thiab txias yog dab tsi.Tom qab ntawd tsuas yog pib los ntawm kev daws teeb meem dua.Qhov tseem ceeb yog tias koj yuav tsum paub txog hom beryllium tooj liab, cov khoom siv tshuaj thiab cov txheej txheem kev laus ntawm cov beryllium tooj liab sib txawv, los yog sab laj nrog cov chaw tsim khoom ntawm cov khoom siv rau kev kho cua sov kom raug.

Yuav ua li cas kom sov kev kho mob ntawm tawv bronze
Tawv bronze?Nws yuav tsum yog beryllium bronze, txoj cai?Kev kho cua sov kom muaj zog ntawm beryllium bronze feem ntau yog kev kho mob + kev laus.Cov kev kho mob sib txawv raws li qhov tshwj xeeb beryllium bronze thiab cov kev cai tshwj xeeb ntawm ib feem.Raws li ib txwm muaj, cua sov ntawm 800 ~ 830 degrees yog siv.Yog tias nws yog siv los ua cov khoom elastic, cov cua kub yog 760 ~ 780.Raws li qhov ua tau zoo thickness ntawm qhov chaw, cov cua sov thiab tuav lub sij hawm kuj txawv.Qhov teeb meem tshwj xeeb yog txheeb xyuas kom meej, feem ntau 8 ~ 25 feeb.Qhov kub ntawm kev laus feem ntau yog 320. Ib yam li ntawd, cov kev cai tshwj xeeb txawv raws li cov khoom siv ntawm cov khoom.Lub sij hawm laus yog 1 mus rau 2 teev rau cov khoom nrog hardness thiab hnav tsis kam, thiab 2 mus rau 3 teev rau cov khoom nrog elasticity.Teev.

Cov txheej txheem tshwj xeeb yuav tsum tau hloov kho raws li qhov sib txawv ntawm beryllium bronze, cov duab thiab qhov loj ntawm cov khoom, thiab cov khoom siv kawg yuav tsum tau ua.Tsis tas li ntawd, cov cua kub ntawm beryllium bronze yuav tsum tau siv cov cua sov los yog lub tshuab nqus tsev kho cua sov.Feem ntau siv cov huab cua tiv thaiv muaj xws li chav, ammonia, hydrogen lossis charcoal, nyob ntawm seb cov xwm txheej tshwj xeeb ntawm koj qhov chaw.
Yuav kho beryllium tooj liab li cas?
Beryllium tooj liab yog ib qho muaj ntau yam nag lossis daus hardening alloy.Tom qab kev daws teeb meem thiab kev laus kev kho mob, lub zog tuaj yeem ncav cuag 1250-1500MPa.Nws cov yam ntxwv kho cua sov yog: tom qab kev kho cov tshuaj, nws muaj cov yas zoo 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 hardness thiab lub zog kuj tseem txhim kho.

Kev kho cua sov ntawm beryllium tooj liab tuaj yeem muab faib ua kev kho annealing, kev kho tshuaj thiab kev laus kev kho mob tom qab kev daws teeb meem.

Kev kho hluav taws rov qab (rov qab) tau muab faib ua:

(1) Nruab nrab softening annealing, uas tuaj yeem siv los ua cov txheej txheem softening hauv nruab nrab ntawm kev ua haujlwm.

(2) Stabilized tempering yog siv los tshem tawm cov machining kev nyuaj siab generated thaum lub sij hawm precision springs thiab calibration, thiab stabilize lub sab nraud qhov ntev.

(3) Kev ntxhov siab rau kev ntxhov siab yog siv los tshem tawm cov kev ntxhov siab ntawm kev ua haujlwm thaum lub sij hawm machining thiab calibration.
