Beryllium bhuronzi imhando dzakasiyana-siyana dzekunaya kwemvura inoomesa alloy. Mushure mekugadzirisa kwakasimba uye kurapwa kwekuchembera, simba rinogona kusvika 1250-1500MPa (1250-1500kg). Hunhu hwayo hwekupisa kupisa ndeiyi: ine yakanaka plasticity mushure mekugadzirisa kwakasimba kurapwa uye inogona kuremara nekushanda kunotonhora. Nekudaro, mushure mekuchembera kurapwa, ine yakanakisa elastic muganho, uye kuoma kwayo uye simba zvinovandudzwa.
(1) Solid solution kurapwa kweberyllium bronze
Kazhinji, tembiricha yekudziya yekurapa mhinduro iri pakati pe780-820 ℃. Zvemidziyo inoshandiswa seyakatsetseka, 760-780 ℃ inoshandiswa, kunyanya kudzivirira zviyo zvakakora kubva pakukanganisa simba. Kufanana kwekushisa kwechoto chekugadzirisa mhinduro kunofanirwa kunyatsodzorwa mukati me ± 5 ° C. Nguva yekubata inogona kuverengerwa seawa imwe/25mm. Kana beryllium bhuronzi yaiswa pasi yakasimba mhinduro kudziyisa kurapwa mumhepo kana oxidizing mhepo, oxide firimu rinoumbwa pamusoro. Kunyangwe iine mhedzisiro shoma pamichina zvinhu mushure mekusimba kwezera, zvinokanganisa hupenyu hwesevhisi yemuumbi wemidziyo panguva yekushanda kunotonhora. Kuti udzivise oxidation, inofanira kupiswa muvira rekutsvaira kana kuparara kweammonia, inert gasi, kuderedza mhepo (yakadai sehydrogen, carbon monoxide, nezvimwewo) kuti uwane chiedza chakajeka chekurapa. Mukuwedzera, kutarisa kunofanira kubhadharwa kupfupisa nguva yekuendesa (panguva yekudzima) zvakanyanya sezvinobvira, kana zvisina kudaro iyo mechanical properties mushure mekukwegura ichakanganiswa. Zvinhu zvakatetepa hazvipfuure masekonzi matatu, uye zvikamu zvakajairika hazvipfuure masekonzi mashanu. Iyo yekudzima svikiro inowanzoshandisa mvura (hapana kudziyisa kunodiwa). Ehe, oiri inogona zvakare kushandiswa kune zvikamu zvine maumbirwo akaomarara kudzivirira deformation.
(2) Kukwegura kurapwa kweberyllium bronze
Tembiricha yekuchembera yeberyllium bronze ine hukama neBe content. Ese alloys ane isingasviki 2.1% Iva anofanirwa kuve akura. Kune alloys ane Iva mukuru kupfuura 1.7%, iyo yakakwana yekuchembera tembiricha ndeye 300-330 ° C, uye nguva yekubata ndeye 1-3 maawa (zvichienderana nechimiro uye ukobvu hwechikamu). Kune yakanyanya conductive electrode alloys neBe less than 0.5%, nekuda kwekuwedzera kunyungudika, yakanyanya kuchembera tembiricha ndeye 450-480 ° C uye nguva yekubata i1-3 maawa. Mumakore achangopfuura, mbiri-nhanho uye yakawanda-nhanho kuchembera zvakare yakagadziridzwa, ndiko kuti, kuchembera kwenguva pfupi pakupisa kwakanyanya uyezve-yenguva refu yekuvharira kuchembera pakudzika kwakadzika. Zvakanakira izvi ndezvekuti mashandiro acho anovandudzwa asi deformation yakaderedzwa. Kuti uvandudze iyo dimensional kurongeka kweberyllium bronze mushure mekuchembera, zvigadziriso zvinogona kushandiswa kuchembera, uye dzimwe nguva nhanho mbiri dzakasiyana dzekuchembera dzinogona kushandiswa.
(3) Kushushikana kwekunetseka kurapwa kweberyllium bronze
Iyo yekuzorodza yekurerutsa tembiricha yeberyllium bronze ndeye 150-200 ℃ uye nguva yekubata i1-1.5 maawa. Inogona kushandiswa kubvisa zvakasara kushushikana kunokonzerwa nesimbi yekucheka, kutwasanudza, kutonhora kuumba, nezvimwewo, uye kudzikamisa chimiro uye dimensional kurongeka kwezvikamu panguva yekushandiswa kwenguva refu.
