Beryllium mhangura, inozivikanwawo semhangura beryllium, CuBe kana beryllium bronze, isimbi alloy yemhangura uye 0.5 kusvika 3% beryllium, uye dzimwe nguva iine zvimwe zvinhu zvealloying, uye ine yakakosha simbi uye inoshanda hunhu hwekuita.

Properties

Beryllium mhangura is ductile, weldable, uye machinable alloy.Inoshingirira kune asiri-oxidizing asidhi (semuenzaniso, hydrochloric acid, kana kabhoni asidhi), kune zvigadzirwa zvekuora epurasitiki, kupfeka zvinokuvadza uye kuputika.Uyezve, inogona kupiswa-inorapwa kuti ivandudze simba rayo, kusimba, uye magetsi conductivity.

Sezvo beryllium ine chepfu pane zvimwe zvinonetsa zvekuchengetedza pakubata ma alloys ayo.Muchimiro chakasimba uye sezvikamu zvakapedzwa, beryllium mhangura hairatidze chero njodzi yehutano.Nekudaro, kufema guruva rayo, sekuumbwa kana kugadzira kana welding kunogona kukonzera kukuvara kwakanyanya kwemapapu.[1]Makomboni eBeryllium anozivikanwa necarcinogens yemunhu kana akafemeswa.[2] Nekuda kweizvozvo, mhangura yeberyllium dzimwe nguva inotsiviwa nemhangura yakachengetedzeka yakaita seCu-Ni-Sn bronze.[3]

Uses

Beryllium mhangura inoshandiswa muzvitubu uye zvimwe zvikamu zvinofanirwa kuchengetedza maumbirwo azvo panguva dzavari kudzokororwa kuomerwa.Nekuda kwekuita kwayo kwemagetsi, inoshandiswa mune yakaderera-ikozvino mabhatiri uye magetsi ekubatanidza.Uye nekuti Beryllium mhangura haipedzi asi yakasimba mumuviri uye isina magineti, inoshandiswa kugadzira zvishandiso zvinogona kushandiswa munzvimbo dzinoputika kana nekuda kweEOD.Mhando dzematurusi akasiyana-siyana dziripo eg screwdrivers, pliers, spanners, cold chisel nesando [4].Imwe simbi dzimwe nguva inoshandiswa kune isiri-sparking maturusi ialuminium bronze.Zvichienzaniswa nemidziyo yakagadzirwa nesimbi, Beryllium mhangura maturusi anodhura, haana kusimba uye kupera nokukurumidza.Nekudaro, zvakanakira kushandisa Beryllium mhangura munzvimbo dzine njodzi zvinodarika izvi zvisingabatsiri.

Beryllium mhangura inowanzoshandiswa mukugadzira zviridzwa zvemhando yepamusoro-soro, kunyanya tamborini uye katatu, uko inokosheswa nenzwi rayo rakajeka uye mutinhimira wakasimba.Kusiyana nezvimwe zvinhu zvakawanda, chiridzwa chakaumbwa neberyllium mhangura chinochengetedza toni inowirirana uye timbre kwenguva yakareba sekunge zvinhu zvichiramba.“Manzwiro” ezviridzwa zvakadaro akapfuma uye ane mutsindo zvokuti anoita seasiri panzvimbo paanoshandiswa muzvidimbu zvakasviba, zvine mutinhimira zvemumhanzi wekirasi.

Beryllium mhangura yakawanawo kushandiswa mu-ultra-low tembiricha cryogenic midziyo, senge dilution refrigerator, nekuda kwekusanganiswa kwayo kwesimba remuchina uye yakanyanya kupisa yekupisa mune ino tembiricha.

Beryllium copper yakashandiswawo kubaya mabara ezvombo, [5] kunyangwe mashandisirwo akadaro asina kujairika nekuti mabara anogadzirwa nesimbi alloys anodhura zvakanyanya, asi ane zvinhu zvakafanana.

Beryllium mhangura inoshandiswawo kuyera-ipo-kuchera maturusi mune inotungamira (slant drilling) indasitiri yekuchera.Makambani mashoma anogadzira zvishandiso izvi GE (QDT tensor positive pulse tool) uye Sondex (Geolink negative pulse tool).Iyo isiri-magnetic alloy inodiwa sezvo magnetometers anoshandiswa pakuverenga anogamuchirwa kubva pachishandiso.

Alloys

High simba beryllium copper alloys ine kusvika 2.7% ye beryllium (cast), kana 1.6-2% ye beryllium inenge 0.3% cobalt (yakagadzirwa).Iyo yakakwirira mechanical simba inowanikwa nekunaya kwemvura kuoma kana kuoma kwezera.Thermal conductivity yeaya alloys iri pakati pesimbi nealuminium.Iyo yakakandwa alloys inowanzoshandiswa sezvinhu zvejekiseni molds.Iyo yakagadziriswa alloys inosarudzwa neUNS seC172000 kusvika kuC17400, iyo yakakandwa alloys ndeye C82000 kusvika kuC82800.Kuomeswa kwacho kunoda kutonhora nekukurumidza kwesimbi yakanyungudutswa, zvichiita kuti pave neyakaomarara mamiriro e beryllium mumhangura, inozochengetwa pa200-460 °C kweinenge awa, zvichiita kunaya kwemetastable beryllide crystals mumhangura matrix.Kuwedzeredza kunodzivirirwa, sechimiro chechimiro chechimiro chinopedza iyo beryllide makristasi uye kuderedza kuwedzera kwesimba.Iwo beryllides akafanana mune ese akakandwa uye akagadzirwa alloys.

High conductivity beryllium copper alloys ine inosvika 0.7% beryllium, pamwe neimwe nickel necobalt.Kupisa kwavo kwekupisa kuri nani pane kwealuminium, zvishoma zvishoma pane yakachena mhangura.Vanowanzo shandiswa semagetsi emagetsi mumagetsi.
