Beryllium tooj liab, tseem hu ua tooj liab beryllium, CuBe los yog beryllium bronze, yog cov hlau alloy ntawm tooj liab thiab 0.5 mus rau 3% beryllium, thiab qee zaum nrog lwm cov alloying ntsiab lus, thiab muaj cov hlau tseem ceeb thiab kev ua haujlwm zoo.
Cov khoom
Beryllium tooj liab yog ductile, weldable, thiab machinable alloy.Nws yog resistant rau non-oxidizing acids (piv txwv li, hydrochloric acid, los yog carbonic acid), rau yas decomposition khoom, abrasive hnav thiab galling.Tsis tas li ntawd, nws tuaj yeem raug kho cua sov los txhim kho nws lub zog, durability, thiab hluav taws xob conductivity.
Raws li beryllium yog tshuaj lom, muaj qee qhov kev txhawj xeeb txog kev nyab xeeb rau kev tuav nws cov alloys.Nyob rau hauv daim ntawv thiab raws li cov khoom tiav, beryllium tooj liab tsis muaj kev phom sij tshwj xeeb.Txawm li cas los xij, ua pa nws cov plua plav, raws li tsim thaum machining lossis vuam yuav ua rau mob ntsws loj.[1] Beryllium tebchaw yog paub tib neeg carcinogens thaum nqus tau.[2] Yog li ntawd, beryllium tooj liab yog qee zaum hloov los ntawm kev nyab xeeb tooj liab hlau xws li Cu-Ni-Sn bronze.[3]
Siv
Beryllium tooj liab yog siv nyob rau hauv springs thiab lwm qhov chaw uas yuav tsum tau khaws lawv cov duab nyob rau hauv lub sij hawm nyob rau hauv uas lawv yuav raug rov strained.Vim nws cov hluav taws xob conductivity, nws yog siv nyob rau hauv qis-tam sim no hu rau roj teeb thiab hluav taws xob connectors.Thiab vim tias Beryllium tooj liab tsis muaj qhov tsis zoo tab sis lub cev tawv thiab tsis muaj hlau nplaum, nws yog siv los ua cov cuab yeej uas tuaj yeem siv rau hauv qhov chaw tawg lossis rau lub hom phiaj EOD.Ntau yam cuab yeej muaj xws li cov ntsia hlau, pliers, spanners, txias chisels thiab rauj [4].Lwm cov hlau qee zaum siv rau cov cuab yeej tsis muaj teeb meem yog aluminium bronze.Piv nrog rau cov cuab yeej ua los ntawm cov hlau, Beryllium tooj liab cov cuab yeej kim dua, tsis muaj zog thiab hnav sai dua.Txawm li cas los xij, qhov zoo ntawm kev siv Beryllium tooj liab nyob rau hauv ib puag ncig txaus ntshai tshaj qhov tsis zoo no.
Beryllium tooj liab kuj nquag siv nyob rau hauv kev tsim cov cuab yeej ua haujlwm zoo, tshwj xeeb tshaj yog tambourine thiab daim duab peb sab, qhov twg nws yog khoom plig rau nws lub suab meej thiab muaj zog resonance.Tsis zoo li feem ntau lwm cov ntaub ntawv, ib qho cuab yeej muaj li ntawm beryllium tooj liab yuav tuav lub suab zoo ib yam thiab timbre ntev npaum li cov ntaub ntawv resonates.Qhov "xav" ntawm cov twj paj nruag zoo li no yog nplua nuj thiab zoo nkauj rau lub ntsiab lus uas lawv zoo li tawm ntawm qhov chaw thaum siv tsaus, ntau dua cov suab paj nruag classical.
Beryllium tooj liab kuj tau pom siv nyob rau hauv ultra-low kub cryogenic cov khoom, xws li dilution tub yees, vim hais tias ntawm nws ua ke ntawm txhua yam muaj zog thiab kuj thermal conductivity nyob rau hauv no kub ntau yam.
Beryllium tooj liab kuj tau siv rau armor tho mos txwv, [5] txawm tias ib qho kev siv no txawv txawv vim cov mos txwv ua los ntawm cov hlau alloys tsis tshua kim, tab sis muaj cov khoom zoo sib xws.
Beryllium tooj liab kuj tseem siv rau kev ntsuas-thaum-drilling cov cuab yeej hauv kev taw qhia (slant drilling) kev lag luam drilling.Ob peb lub tuam txhab tsim cov cuab yeej no yog GE (QDT tensor zoo mem tes cuab tam) thiab Sondex (Geolink tsis zoo mem tes cuab tam).Yuav tsum muaj cov hlau nplaum uas tsis yog hlau nplaum vim cov hlau nplaum siv rau kev xam tau txais los ntawm lub cuab yeej.
Cov hlau nplaum
Lub zog loj beryllium tooj liab alloys muaj txog li 2.7% ntawm beryllium (cam khwb cia), los yog 1.6-2% ntawm beryllium nrog txog 0.3% cobalt (wrought).Lub siab mechanical zog yog ua tiav los ntawm nag lossis daus hardening lossis hnub nyoog hardening.Lub thermal conductivity ntawm cov alloys nyob nruab nrab ntawm cov hlau thiab txhuas.Cov cam khwb cia hlau feem ntau siv los ua cov khoom siv rau kev txhaj tshuaj pwm.Lub wrought alloys yog tsim los ntawm UNS li C172000 rau C17400, cov cam khwb cia hlau yog C82000 rau C82800.Cov txheej txheem hardening yuav tsum tau ua kom txias sai ntawm cov hlau annealed, uas ua rau lub xeev muaj zog ntawm beryllium hauv tooj liab, uas tom qab ntawd khaws cia ntawm 200-460 ° C rau tsawg kawg ib teev, ua kom yooj yim nag lossis daus ntawm metastable beryllide crystals hauv tooj liab matrix.Overaging yog zam, raws li ib qho kev sib npaug theem cov ntaub ntawv uas depletes lub beryllide crystals thiab txo lub zog li.Cov beryllides zoo sib xws hauv ob qho tib si cam khwb cia thiab wrought alloys.
High conductivity beryllium tooj liab alloys muaj txog li 0.7% beryllium, nrog rau qee cov npib tsib xee thiab cobalt.Lawv thermal conductivity zoo dua li ntawm txhuas, tsuas yog me ntsis tsawg dua tooj liab ntshiab.Lawv feem ntau yog siv los ua hluav taws xob tiv tauj hauv cov khoom sib txuas.
