I-beryllium yobhedu, ekwabizwa ngokuba yi-copper beryllium, iCuBe okanye i-beryllium bronze, yintsimbi yobhedu kunye ne-0.5 ukuya kwi-3% ye-beryllium, kwaye ngamanye amaxesha nezinye izinto ezidibeneyo, kwaye inomsebenzi obalulekileyo wesinyithi kunye neempawu zokusebenza.

Iipropati

I-beryllium yobhedu yi-ductile, i-weldable, kunye ne-machinable alloy.Iyakwazi ukumelana ne-non-oxidizing acids (umzekelo, i-hydrochloric acid, okanye i-carbonic acid), kwiimveliso zeplastiki zokubola, ukuguga kunye ne-galling.Ngaphaya koko, inokunyangwa ubushushu ukuze iphucule amandla ayo, ukuqina, kunye nokuhanjiswa kombane.

Njengoko i-beryllium inetyhefu kukho iinkxalabo zokhuseleko zokuphatha ii-alloys zayo.Ikwimo eqinileyo nanjengamalungu agqityiweyo, ubhedu lweberyllium alubonakalisi bungozi buthile kwimpilo.Nangona kunjalo, ukuphefumla uthuli lwayo, njengoko lwenziwa xa kusetyenzwa okanye ukuwelda kunokubangela umonakalo omkhulu emiphungeni.[1] Iikhompawundi zeBeryllium zaziwa zii-carcinogens zabantu xa zisethiwe.[2] Ngenxa yoko, i-beryllium yobhedu ngamanye amaxesha ithathwa indawo yealloys zethusi ezikhuselekileyo ezifana ne-Cu-Ni-Sn bronze.[3]

Usebenzisa

Ubhedu lweBeryllium lusetyenziswa kwimithombo kunye nezinye iindawo ekufuneka zigcine imilo yazo ngamaxesha apho ziphantsi koxinzelelo oluphindaphindiweyo.Ngenxa ye-conductivity yayo yombane, isetyenziselwa uqhagamshelwano oluphantsi lwangoku kwiibhetri kunye nezixhumi zombane.Kwaye ngenxa yokuba i-beryllium yobhedu ayivuthisi kodwa iqinile kwaye ingenamagnetic, isetyenziselwa ukwenza izixhobo ezinokuthi zisetyenziswe kwiindawo eziqhumayo okanye ngeenjongo ze-EOD.Iintlobo ngeentlobo zezixhobo ziyafumaneka umz. izikrurudrayiva, iipliers, izipani, iitshizili ezibandayo kunye neehamile [4].Enye intsimbi ngamanye amaxesha esetyenziselwa izixhobo ezingatshisiyo yibronze ye-aluminium.Xa kuthelekiswa nezixhobo ezenziwe ngentsimbi, izixhobo zobhedu zeBeryllium zibiza kakhulu, azinamandla kwaye ziguga ngokukhawuleza.Nangona kunjalo, iingenelo zokusebenzisa i-beryllium copper kwiindawo ezinobungozi zidlula ezi zinto zingalunganga.

Iberyllium yobhedu ikwasetyenziswa rhoqo xa kusenziwa izixhobo zokubethwa ezikumgangatho ophezulu, ngakumbi itamborini kunye nonxantathu, apho ixabiseke kakhulu ngenxa yethoni yayo ecacileyo kunye nesandi esinamandla.Ngokungafaniyo nezinye izinto ezininzi, isixhobo esakhiwe nge-beryllium copper siya kugcina ithoni ehambelanayo kunye ne-timbre ixesha elide njengoko izinto zisebenza.“Imvakalelo” yezo zixhobo zomculo ityebile yaye imnandi kangangokuba zibonakala zingekho ngqiqweni xa zisetyenziswa kumculo omnyama nonesingqi esingakumbi.

Ubhedu lweBeryllium lukwafumene ukusetyenziswa kwisixhobo se-cryogenic sobushushu obuphantsi kakhulu, njengeefriji zokuxutywa, ngenxa yokudityaniswa kwamandla omatshini kunye ne-thermal conductivity ephezulu kolu luhlu lobushushu.

Iberyllium copper iye yasetyenziselwa iimbumbulu zokugqobhoza isikrweqe, [5] nangona naluphi na usebenziso olunjalo lungaqhelekanga kuba iimbumbulu ezenziwe kwialloys zentsimbi zingabizi kakhulu, kodwa zineempawu ezifanayo.

Ubhedu lweBeryllium lukwasetyenziselwa ukulinganisa-ngelixa-ukugaya izixhobo kwi-directional (slant drilling) ishishini lokugaya.Iinkampani ezimbalwa ezenza ezi zixhobo ziyi-GE (QDT tensor positive pulse tool) kunye ne-Sondex (i-Geolink negative pulse tool).I-alloy engeyiyo-magnetic iyafuneka njengoko i-magnetometers isetyenziselwa izibalo ezifunyenwe kwisixhobo.

Ingxubevange

Amandla aphezulu e-beryllium copper alloys aqukethe ukuya kwi-2.7% ye-beryllium (i-cast), okanye i-1.6-2% ye-beryllium malunga ne-0.3% ye-cobalt (eyenziwe).Amandla aphezulu omatshini aphunyezwa ngokuqina kwemvula okanye ukuqina kweminyaka.I-thermal conductivity yezi alloys ilala phakathi kweentsimbi kunye ne-aluminium.I-alloys etyhidiweyo isetyenziswa rhoqo njengezinto zokubumba iinaliti.I-alloys edibeneyo ikhethwe yi-UNS njenge-C172000 ukuya kwi-C17400, i-alloys ephosiweyo yi-C82000 kwi-C82800.Inkqubo yokuqina ifuna ukupholisa ngokukhawuleza kwesinyithi esifakwe emanzini, okukhokelela kwisisombululo esiqinileyo se-beryllium kwi-copper, ethi ke igcinwe kwi-200-460 ° C ubuncinane iyure, iququzelele imvula yeekristale ze-beryllide ze-metastable kwi-matrix yobhedu.Ukugqithisa kuyaphetshwa, njengefom yesigaba sokulinganisa echitha i-crystals ye-beryllide kwaye inciphisa ukongezwa kwamandla.I-beryllides iyafana kuzo zombini ii-alloys ezenziweyo kunye ne-alloys.

I-conductivity ephezulu ye-beryllium i-alloys yobhedu iqulethe ukuya kwi-0.7% i-beryllium, kunye ne-nickel kunye ne-cobalt.I-conductivity yabo ye-thermal ingcono kune-aluminium, ingaphantsi kancinci kunobhedu olusulungekileyo.Ngokuqhelekileyo zisetyenziswa njengabafowunelwa bombane kwizihlanganisi.
