I-Beryllium yethusi, eyaziwa nangokuthi i-copper beryllium, i-CuBe noma i-beryllium bronze, iyingxube yensimbi yethusi kanye ne-beryllium engu-0.5 kuya ku-3%, futhi ngezinye izikhathi nezinye izakhi ze-alloying, futhi inezimfanelo ezibalulekile zokusebenza kwensimbi nokusebenza.

Izakhiwo

I-Beryllium yethusi iyingxubevange eshisekayo, eshiselayo, nemachinable.Imelana nama-asidi angewona oxidizing (isibonelo, i-hydrochloric acid, noma i-carbonic acid), emikhiqizweni yokubola kwepulasitiki, ukuguga nokugwazeka.Ngaphezu kwalokho, ingaphathwa ngokushisa ukuze ithuthukise amandla ayo, ukuqina, kanye nokusebenza kukagesi.

Njengoba i-beryllium inobuthi kunokukhathazeka okuthile kokuphepha ekuphatheni ama-alloys ayo.Isesimweni esiqinile futhi njengezingxenye eziqediwe, ithusi le-beryllium alivezi ingozi ethile yezempilo.Nokho, ukuphefumula uthuli lwayo, njengoba kwakheka lapho kwenziwa imishini noma ukushisela kungase kubangele umonakalo omkhulu wamaphaphu.[1]Izingxube ze-Berryllium zaziwa ngama-carcinogens abantu lapho ehogeliwe.[2] Ngenxa yalokho, ithusi le-beryllium ngezinye izikhathi lithathelwa indawo ama-alloys ethusi aphephile njenge-Cu-Ni-Sn bronze.[3]

Isebenzisa

Ithusi le-beryllium lisetshenziswa eziphethwini nakwezinye izingxenye okufanele zigcine ukwakheka kwazo ngezikhathi lapho zibhekene nokucindezeleka okuphindaphindiwe.Ngenxa ye-conductivity yayo kagesi, isetshenziswa koxhumana nabo abaphansi bamanje kumabhethri nezixhumi zikagesi.Futhi ngenxa yokuthi ithusi le-Beryllium alinanhlansi kodwa liqinile ngokomzimba futhi alinawo uzibuthe, lisetshenziselwa ukwenza amathuluzi angasetshenziswa ezindaweni eziqhumayo noma ngezinjongo ze-EOD.Izinhlobo ezahlukene zamathuluzi ziyatholakala isb. izikrudrayivu, izidladla, izipanela, amashizolo abandayo nezando [4].Enye insimbi ngezinye izikhathi esetshenziselwa amathuluzi angashisi ithusi le-aluminium.Uma kuqhathaniswa namathuluzi enziwe ngensimbi, amathuluzi ethusi eBeryllium abiza kakhulu, awaqinile futhi aguga ngokushesha.Kodwa-ke, izinzuzo zokusebenzisa i-Berryllium copper ezindaweni eziyingozi zidlula lezi zimo ezimbi.

Ithusi le-beryllium libuye lisetshenziswe kaningi ekwenzeni izinsimbi ezishaywayo ezisezingeni eliphezulu, ikakhulukazi ithamborini nonxantathu, lapho laziswa khona ngenxa yephimbo layo elicacile nokuzwakala kwalo okuqinile.Ngokungafani nezinye izinto eziningi, ithuluzi elakhiwe nge-beryllium copper lizogcina ithoni engashintshi kanye ne-timbre inqobo nje uma okubalulekile kusasebenza.“Umuzwa” wezinsimbi ezinjalo ucebile futhi umnandi kangangokuthi ubonakala ungafaneleki lapho usetshenziswa eziculweni ezimnyama, ezinesigqi somculo wakudala.

I-Beryllium yethusi iphinde yathola ukusetshenziswa emishinini yokushisa ephansi ye-cryogenic ye-ultra-low, njengeziqandisi ze-dilution, ngenxa yenhlanganisela yayo yamandla emishini kanye ne-thermal conductivity ephezulu kakhulu kuleli banga lokushisa.

I-Berryllium copper iphinde yasetshenziselwa izinhlamvu zokubhoboza izikhali, [5] nakuba noma yikuphi ukusetshenziswa okunjalo kungavamile ngoba izinhlamvu ezenziwe ngama-alloys ensimbi zingabizi kakhulu, kodwa zinezakhiwo ezifanayo.

I-Beryllium yethusi iphinde isetshenziselwe ukulinganisa-ngenkathi kubhoboza amathuluzi embonini yokumba eqondisayo (i-slant drilling).Izinkampani ezimbalwa ezikhiqiza la mathuluzi yi-GE (QDT tensor positive pulse tool) kanye ne-Sondex (ithuluzi le-Geolink negative pulse).Ingxubevange engeyona-magnetic iyadingeka njengoba kusetshenziswa ama-magnetometer ezibalo ezitholwe ethuluzini.

Ama-alloys

Amandla aphezulu we-beryllium alloys yethusi aqukethe kufika ku-2.7% we-beryllium (cast), noma u-1.6-2% we-beryllium cishe ne-cobalt engu-0.3% (eyenziwe).Amandla aphezulu emishini atholakala ngokuba lukhuni kwezulu noma ukuqina kweminyaka.I-thermal conductivity yalezi zingxubevange iphakathi kwezinsimbi ne-aluminium.Ama-alloys asetshenziswa kaningi njengempahla yokubumba umjovo.Ama-alloys akhiwe akhethwe yi-UNS njenge-C172000 kuya ku-C17400, ama-alloys ahlanganisiwe yi-C82000 kuya ku-C82800.Inqubo yokuqina idinga ukupholiswa okusheshayo kwensimbi efakwe emanzini, okuholela kusixazululo sesimo esiqinile se-beryllium yethusi, esigcinwa ku-200-460 °C okungenani ihora, okwenza kube lula ukuna kwamakristalu e-beryllide e-metastable ku-matrix yethusi.Ukweqisa kuyagwenywa, njengoba kwakheka isigaba sokulinganisa esiqeda amakristalu e-beryllide futhi sinciphise ukuthuthukiswa kwamandla.Ama-beryllide afana kuwo womabili ama-alloys aqoshiwe kanye nama-alloys.

Ama-alloys ethusi e-beryllium aphezulu aqukethe i-beryllium efika ku-0.7%, kanye nenye nickel ne-cobalt.I-thermal conductivity yabo ingcono kune-aluminium, ingaphansi kancane kunethusi elihlanzekile.Ngokuvamile zisetshenziswa njengokuxhumana kukagesi kuzixhumi.
