Ukucutshungulwa kweBeryllium

I-beryllium bronze iyi-alloy eqinisiwe yokuguga kwezulu.Inqubo evamile yokwelapha ukushisa kwe-beryllium bronze enamandla amakhulu ukugcina izinga lokushisa liku-760 ~ 830 ℃ isikhathi esifanele (okungenani imizuzu engu-60 ngepuleti eliwugqinsi elingu-25mm), ukuze i-solute atomic beryllium incibilike ngokugcwele ku-matrix yethusi ukuze yakha isigaba esingu-α se-cubic lattice egxile ebusweni.Isixazululo esiqinile se-Supersaturated.Kamuva, izinga lokushisa lagcinwa ku-320-340 °C amahora angu-2-3 ukuze kuqedelwe inqubo yokuchithwa kwe-desolubilization kanye nemvula ukuze kwakhiwe isigaba sika-γ' (isigaba se-CuBe2 metastable).Ukuhambisana kwalesi sigaba ne-matrix kudala insimu yokucindezeleka eqinisa i-matrix.Inqubo evamile yokwelashwa kokushisa kwe-high-conductivity beryllium bronze iwukugcina isikhathi esithile ekushiseni okuphezulu kwe-900-950 ° C ukuze kuqedelwe inqubo yesisombululo esiqinile, bese uyigcina ku-450-480 ° C ngo-2-4. amahora ukuze kuzuzwe inqubo ye-desolubilization kanye nemvula.Njengoba i-cobalt eyengeziwe noma i-nickel yengezwe ku-alloy, izinhlayiya zayo eziqinisa ukuhlakazeka ziyizinhlanganisela ze-intermetallic ezakhiwe yi-cobalt noma i-nickel ne-beryllium.Ukuze kuqhutshekwe kuthuthukiswe amandla ingxubevange, izinga elithile ukusebenza abandayo ngokuvamile kwenziwa phezu ingxubevange emva ukwelashwa ukushisa isixazululo nangaphambi ukuguga ukwelashwa ukushisa, ukuze kuzuzwe esibanzi ukuqinisa umphumela umsebenzi obandayo ukuqina kanye nobudala ukuqina. .Iziqu zayo zokusebenza ezibandayo ngokuvamile azidluli ama-37%.Ukwelashwa kokushisa kwesixazululo ngokuvamile kufanele kwenziwe ngumkhiqizi we-alloy.Ngemuva kokuthi umsebenzisi eshaye isixazululo semicu ephethwe ukushisa negoqwe ngamakhaza abe yizingxenye, abe eseziguga ukuze athole izakhi zentwasahlobo ezinamandla aphezulu.Eminyakeni yamuva nje, i-United States ithuthukise amapheshana anokwelashwa kokushisa okuguga okugcwaliswe abakhiqizi bethusi be-beryllium, futhi amakhasimende angawashaya ngokuqondile abe izingxenye ezizosetshenziswa.Ngemva kokuba ithusi le-beryllium selicutshungulwe ngezinqubo ezihlukahlukene, izinhlamvu zaseYurophu nase-United States ze-alloy state yilezi: Isixazululo se-annealed state (i-annealed), i-alloy isesimweni esithambile kakhulu, kulula ukugxivizwa futhi yakheke, futhi idinga. ukuqhubeka nokusebenza okubandayo noma ukwelashwa okuqondile kokuguga..H imele isimo sokuqina komsebenzi (hard).Uma sithatha ishidi eligoqekile njengesibonelo, ama-37% edigri yomsebenzi obandayo anzima ngokuphelele (H), ama-21% eziqu zomsebenzi obandayo anzima kakhulu (1/2H), kanti u-11% weziqu zomsebenzi obandayo ngu-1 / 4 isimo esiqinile (1/4H), umsebenzisi angakhetha isimo esifanele esithambile nesiqinile ngokusho kobunzima bokubhoboza ukuma kwengxenye.I-T imele isimo sokwelashwa kokushisa (ukwelashwa kokushisa) osekukhulile futhi kwaqiniswa.Uma inqubo yokuqiniswa okuphelele kokuguga nokuguga yamukelwa, isimo sayo simelelwa yi-HT.
