Thepa ea Metal Beryllium

Beryllium ke tšepe e bohlooho, e bobebe (boima ba 1.848 g/cm3), e thata, 'me ho bonolo ho etsa lera le letenya le sireletsang oxide holim'a moea, kahoo e batla e tsitsitse mocheso oa kamore.Beryllium e na le ntlha e qhibilihang ea 1285 ° C, e phahameng haholo ho feta lisebelisoa tse ling tse khanyang (magnesium, aluminium).Ka hona, li-alloys tse nang le beryllium li bobebe, li thata, 'me li hana mocheso o phahameng,' me ke lisebelisoa tse loketseng bakeng sa ho etsa lisebelisoa tsa sefofane le sefofane.Ka mohlala, tšebeliso ea li-alloys tsa beryllium ho etsa li-rocket casings ho ka fokotsa boima ba 'mele haholo;tšebeliso ea li-alloys tsa beryllium ho etsa li-satellite tsa maiketsetso le lifofane tsa sepakapaka li ka netefatsa polokeho ea sefofane.

"Mokhathala" ke bothata bo tloaelehileng ba litšepe tse akaretsang.Ka mohlala, thapo ea nako e telele e jereng mojaro e tla robeha ka lebaka la "mokhathala", 'me selemo se tla lahleheloa ke elasticity ka lebaka la "mokhathala" haeba e hatelloa khafetsa le ho phutholoha.Metal beryllium e na le ts'ebetso e khahlanong le mokhathala.Ka mohlala, eketsa ka 1% tšepe beryllium ho tšepe e qhibilihisitsoeng.Nako ea selemo e entsoeng ka tšepe ena ea alloy e ka otlolla ka makhetlo a limilione tse 14 ka nako e sa khaotseng ntle le ho lahleheloa ke elasticity ka lebaka la "mokhathala", esita le boemong ba "mocheso o mofubelu" Ntle le ho lahleheloa ke ho feto-fetoha ha eona, e ka hlalosoa e le "indomitable".Haeba hoo e ka bang 2% ea tšepe ea beryllium e eketsoa ho boronse, matla a tsitsitseng le elasticity ea koporo ena ea beryllium alloy ha e fapane le tšepe.Ka hona, beryllium e tsejoa e le "tšepe e hanyetsanang le mokhathala".

Ntho e 'ngoe ea bohlokoa ea tšepe ea beryllium ke hore ha e chese ha e otla, kahoo li-alloys tsa koporo-nickel tse nang le beryllium li atisa ho sebelisoa ho etsa liboro, lihamore, lithipa le lisebelisoa tse ling tse sebelisoang ka ho khetheha bakeng sa ho sebetsa. thepa e tukang le ho phatloha.

Metal beryllium e boetse e na le thepa ea ho ba pepeneneng ho mahlaseli.Ha re nka li-X-ray e le mohlala, matla a ho phunyeletsa beryllium a matla ho feta a loto ka makhetlo a 20 ’me a matla ho feta a koporo ka makhetlo a 16.Ka hona, beryllium ea tšepe e na le botumo ba "khalase ea tšepe", 'me beryllium e atisa ho sebelisoa ho etsa "lifensetere" tsa X-ray tubes.

Metal beryllium e boetse e na le mosebetsi o motle oa ho fetisa molumo.Lebelo la ho phatlalatsoa ha molumo ka tšepe ea beryllium le ka holimo ho 12,600 m/s, e leng holimo haholo ho feta lebelo la molumo moeeng (340 m/s), metsi (1500 m/s) le tšepe (5200 m/s) .e ratoang ke indasteri ea liletsa tsa mmino.
