I-beryllium yobhedu njenge-alloy edibeneyo ye-beryllium yobhedu, eyaziwa ngokuba yi-beryllium bronze, i-beryllium copper alloy.Yi-alloy eneempawu ezilungileyo zoomatshini, zomzimba kunye neekhemikhali ezibanzi.Emva kokucima kunye nokufudumala, inamandla amakhulu, u-elasticity, ukumelana nokugqoka, ukuxhathisa ukukhathala kunye nokuxhathisa ukushisa.Ngelo xesha, i-beryllium yobhedu nayo ine-conductivity ephezulu yombane., i-thermal conductivity, ukumelana nokubanda kunye ne-non-magnetic, akukho zintlantsi xa zichaphazeleka, kulula uku-weld kunye ne-braze, ukuxhathisa okugqwesileyo kwe-corrosion emoyeni, amanzi amatsha kunye namanzi olwandle.
Yimathiriyeli yomgangatho ophezulu we-elastic kunye nokusebenza kakuhle phakathi kwee-alloys zethusi.Inamandla amakhulu, ukuqina, ukuqina, amandla okudinwa, i-elag encinci, ukuxhathisa ukubola, ukumelana nokunxiba, ukumelana nokubanda, ukuqhuba okuphezulu, okungeyo-magnetic, kwaye akukho zintlantsi xa zichaphazeleka.Uluhlu lweempawu ezibalaseleyo zomzimba, iikhemikhali kunye nezoomatshini.Umbala we-beryllium ubhedu ubonisa imibala emibini ebomvu okanye ephuzi.Kuyinto eqhelekileyo ukuba umbala we-beryllium ubhedu ubonakale uphuzi kwaye ubomvu, kuba ukuphendulwa kweekhemikhali ze-oxidation kwenzeka ngexesha lokuvelisa kunye nenkqubo yokugcina, kwaye umbala uguquka.

Ubhedu lwe-beryllium luhlukaniswe lube lubhedu oluphezulu lwe-beryllium kunye nobhedu oluphantsi lwe-beryllium.Ubhedu oluphezulu lwe-beryllium lubhekisa kubhedu lwe-beryllium kunye nomxholo we-beryllium omkhulu kune-2.0.I-Beryllium yobhedu yinto yokumelana ne-electrode ye-welding ye-welding, ene-conductivity elungileyo yombane kunye ne-thermal kunye nobunzima obuphezulu.Xa i-welding, i-electrode inxiba incinci, isantya sikhawuleza, kwaye iindleko ziphantsi.
Inkqubo yokuvelisa ubhedu lweBeryllium
Inkqubo yokuvelisa i-beryllium yobhedu ihlukaniswe ngamanyathelo amane: ukuveliswa kwe-beryllium-copper master alloy ngendlela yokunciphisa i-carbothermal, ukunyibilika kwe-beryllium yobhedu, i-ingot ye-alloy yobhedu kunye nokuveliswa kwe-beryllium copper alloy plate, i-strip kunye ne-strip.
Ukuveliswa kwe-beryllium-copper master alloys ngokunciphisa i-carbothermal ibhekisela ekunciphiseni ngokuthe ngqo kwe-beryllium kwi-beryllium oxide kunye nekhabhoni yobhedu olutyhidiweyo, ilandelwa yi-alloying yobhedu.Ukuveliswa kwe-beryllium-copper master alloy ngokunciphisa i-carbothermic kwishishini kuqhutyelwa kwisithando sombane se-arc.Isithando sombane se-arc sifakwe kwisitya esitywiniweyo.Umsebenzisi unxiba imaski yegesi.I-% ye-carbon powder ixutywe kwi-ball mill kunye nomhlaba, kwaye emva koko umaleko wobhedu, umgca we-beryllium oxide kunye nomxube we-carbon powder ulayishwe kwisithando sombane se-arc kwiibhetshi, amandla kwaye anyibilike.Xa ipholile ukuya kuma 950 degrees celcius – 1000 degrees celcius, igama lengxubevange ethi beryllium carbide, carbon, kunye nentsalela engumgubo idada, slag, emva koko iphoswe kwi-2.25 kg okanye i-5 kg ​​yeingono ku-950 degrees celcius.
Intlawulo esetyenziselwa ukunyibilikisa i-beryllium yobhedu ialloy ibandakanya intsimbi entsha, i-scrap, i-secondary remelting charge kunye ne-master alloy.
I-Berryllium ngokubanzi isebenzisa i-beryllium-copper master alloy (equlethe i-beryllium 4%);Ngamanye amaxesha i-nickel isebenzisa isinyithi esitsha, oko kukuthi, i-nickel electrolytic, kodwa kungcono ukusebenzisa i-nickel-copper master alloy (equlethe i-20% ye-nickel);i-cobalt isebenzisa i-cobalt-copper master alloy (i-Cobalt 5.5%), kwaye abanye basebenzisa ngokuthe ngqo i-cobalt ecocekileyo;i-titanium yongezwa nge-titanium-copper master alloy (equlethe i-15% ye-titanium, kwaye ezinye ziqulethe i-27.4% ye-titanium), kwaye ezinye zongeza ngokuthe ngqo i-sponge titanium;i-magnesium yi-magnesium- i-Copper master alloy (equlethe i-35.7% ye-magnesium) yongezwa.
Ii-chips (ii-chips zokugaya, ii-chips zokusika, njl. njl.) kunye nezixhobo ezincinci zekona ezenziwe ngexesha lokucubungula zivame ukuphonswa kwiingots emva kokunyibilika kwesibini njengentlawulo yokunyibilikisa;ukongeza kwi-remelting material ehlaziyiweyo, xa i-batching Kwakhona kuqhelekile ukongeza enye inkunkuma yokulahla kunye ne-machining inkunkuma ngokuthe ngqo kwisithando somlilo.
I-ingot ye-beryllium i-alloy copper ihlukaniswe ibe yi-non-vacuum ingot kunye ne-vacuum ingot.Iindlela zokuphosa ingot ye-non-vacuum esetyenziswayo ngoku ekusetyenzisweni kwe-beryllium yokuvelisa i-copper alloy ibandakanya i-iron mold ingot casting, i-flowless ingot casting, i-semi-continuous ingot casting kunye ne-ingot eqhubekayo.Iindlela ezimbini zokuqala zisetyenziswa kuphela kwiifektri ezinezikali ezincinci zemveliso.
Iingcali zithi ukuze ufumane i-beryllium-copper alloy ingots kunye nomxholo ophantsi wegesi, ulwahlulo oluncinci, ukufakwa okuncinci, kunye ne-uniform kunye ne-dense crystal structure, eyona ndlela ingcono kukucoca i-ingots emva kwe-vacuum smelting.Ukuphosa ingot ye-vacuum kunempembelelo ebalulekileyo ekuqinisekiseni umxholo wezinto ezinokuthi zixutywe ngokulula njenge-beryllium kunye ne-titanium.Xa kuyimfuneko, igesi ye-inert ingangeniswa ukukhusela inkqubo yokuphosa ingot.
Inkcazo ye-beryllium yokushisa ukushisa kobhedu: unyango olushushu lwe-beryllium yobhedu Unyango olushushu lwe-beryllium yobhedu lunokwahlulwa lube ngunyango lwe-annealing, unyango lwesisombululo kunye nokuguga emva kokunyanga kwesisombululo.
I-beryllium copper retreat (i-return) yonyango ihlulwe ibe: (1) I-annealing yokuthambisa ephakathi, engasetyenziselwa inkqubo yokuthambisa phakathi kokucubungula.(2) Ukushisa okuzinzile kusetyenziselwa ukuphelisa uxinzelelo lomatshini oluveliswa ngexesha lokuchaneka kwemithombo kunye nokulinganisa, kunye nokuzinzisa imilinganiselo yangaphandle.(3) Ukunciphisa uxinzelelo loxinzelelo kusetyenziselwa ukuphelisa uxinzelelo lomatshini olwenziwe ngexesha lomatshini kunye nokulinganisa.
