Beryllium bronze ndiyo yakajairika kuchembera kunaya kwakasimbiswa alloy.Iyo yakajairwa kupisa kupisa kweyepamusoro-simba beryllium bronze ndeyekuchengetedza tembiricha iri pa760 ~ 830 ℃ kwenguva yakakodzera (angangoita maminetsi makumi matanhatu pa25mm gobvu ndiro), kuitira kuti solute atomic beryllium inonyungudutswa zvizere mumhangura matrix. gadzira α chikamu chechiso-chepakati cubic lattice.Supersaturated solid solution.Zvadaro, tembiricha yakachengetwa pa 320-340 °C kwe 2-3 h kuti ipedze hurongwa hwe desolubilization uye kunaya kwemvura kuumba γ' chikamu (CuBe2 metastable phase).Kubatana kwechikamu ichi nematrix kunogadzira nzvimbo yekushungurudzika inosimbisa matrix.Iyo yakajairika kupisa kupisa maitiro e-high-conductivity beryllium bronze ndeyekuchengeta kwenguva yakati rebei pane yakanyanya tembiricha ye900-950 °C kupedzisa iyo yakasimba mhinduro process, uye woichengeta pa450-480 °C ye2-4. maawa ekuzadzisa desolubilization uye kunaya kwemvura.Sezvo yakawanda cobalt kana nickel yakawedzerwa kune alloy, kupararira kwayo kusimbisa zvimedu zvinonyanya kusanganisa intermetallic zvinoumbwa necobalt kana nickel uye beryllium.Kuti uwedzere kunatsiridza simba reiyo alloy, imwe dhigirii yekushanda inotonhora inowanzoitwa pane alloy mushure memhinduro yekupisa kurapwa uye isati yachembera kupisa kurapwa, kuitira kuti uwane yakazara inosimbisa mhedzisiro yekutonhora basa kuomesa uye kuomesa zera. .Dhigirii rayo rinotonhora rekushanda kazhinji haripfuuri 37%.Solution kupisa kurapwa kunofanira kazhinji kuitwa nemugadziri alloy.Mushure mekunge mushandisi abaya mhinduro inogadziriswa kupisa uye inotonhora-yakakungurutswa mitsetse muzvikamu, ivo vanobva vazvichembera kupisa kurapwa kuti vawane yakakwirira-simba chitubu zvinhu.Mumakore achangopfuura, United States yakagadzira mitsetse ine kuchembera kupisa kurapwa kunopedzwa nevagadziri vemhangura yeberyllium, uye vatengi vanogona kuzvibaya zvakananga kuita zvikamu zvekushandisa.Mushure mekunge beryllium bronze yagadziriswa nemaitiro akasiyana-siyana, mavara muEurope nekuUnited States kune alloy state ndeaya: A means solution annealed state (annealed), iyo alloy iri munyoro, iri nyore kudhindwa nekuumbwa, uye inoda. kuva kumwe kutonhora kushanda kana kunanga kuchembera kurapwa..H inomirira kuti basa-kuomesera mamiriro (hard).Kutora pepa rinotonhora-rakakungurutswa semuenzaniso, 37% yedhigirii rekushanda rinotonhora rakanyatso kuoma (H), 21% yedhigirii rekushanda kunotonhora iri semi-yakaoma (1/2H), uye 11% yedhigirii rekushanda kunotonhora i1. / 4 yakaoma mamiriro (1/4H), mushandisi anogona kusarudza yakakodzera yakapfava uye yakaoma mamiriro maererano nekuoma kwekubaya chimiro chechikamu.T inomiririra mamiriro ekurapa kupisa (kupisa kurapwa) kwave kukwegura uye kusimbiswa.Kana iyo nzira yekusimbisa kwakazara kwe deformation uye kuchembera yakagamuchirwa, iyo nyika inomiririrwa neHT.
