Isebenza njani inkqubo yonyango yobushushu obuphezulu be-beryllium yobhedu

Beryllium ubheduyi-alloy eyomelezayo yokuguga kwemvula.Inkqubo yobushushu obuqhelekileyo bobhedu obuqinileyo be-beryllium kukugcina ubushushu bukwi-760-830 ℃ kangangexesha elifanelekileyo (ubuncinci yi-60min kwipleyiti nganye eyi-25mm), ukuze i-athomu ye-athomu ye-beryllium inyibilike ngokupheleleyo i-matrix yobhedu kwaye yenze ubuso obusembindini we-cubic lettice α Isigaba sesisombululo esiluqilima se-supersaturated.Emva koko, ukugcinwa kobushushu kwi-320 ~ 340 ℃ kwi-2 ~ 3h ukugqiba inkqubo yokuchithwa kwemvula, ukwenza i-γ′ Phase (CuBe2 isigaba se-metastable).Esi sigaba sihambelana nomzimba womzali, okubangelwa intsimi yoxinzelelo kunye nokuqinisa i-matrix.

Isebenza njani inkqubo yonyango yobushushu obuphezulu be-beryllium yobhedu

Inkqubo yonyango yobushushu obuqhelekileyo bobhedu obuphezulu be-beryllium kukugcina ubushushu kwi-900 ~ 950 ℃ kangangexesha elithile ukugqiba inkqubo yesisombululo esiluqilima, kwaye ke ugcine ubushushu kwi-450 ~ 480 ℃ kwi-2 ~ 4h ukuqonda ukupheliswa. inkqubo yemvula.Ngenxa yokongezwa kwe-cobalt engaphezulu okanye i-nickel kwi-alloy, i-dispersion yokuqinisa iinqununu zininzi i-intermetallic compounds eyenziwe yi-cobalt okanye i-nickel kunye ne-beryllium.Ukuze kuphuculwe ngakumbi amandla ingxubevange, ingxubevange isoloko kubanda wasebenza ukuya kumlinganiselo othile emva kokuba unyango ubushushu isisombululo kunye naphambi ukwaluphala unyango ubushushu, ukuze kuzuzwe isiphumo ukomeleza olubanzi umsebenzi obandayo ukuqina kunye nobudala lukhuni.Ukusebenza kwayo okubandayo akudluli kuma-37%.Ukulungiswa kobushushu besisombululo kuya kwenziwa ngokubanzi ngumenzi wealloyi.Umsebenzisi uya kugqobhoza isisombululo esiphathwe ubushushu kunye nomcu opholileyo oqengqelekayo ube ngamacandelo, kwaye emva koko aqhube unyango lobushushu bokwaluphala ukufumana amacandelo aphezulu entwasahlobo.

Kwiminyaka yakutshanje, i-China iphuhlise umcu kunye nonyango lobushushu obuguga obugqitywe nguabenzi bobhedu beryllium, enokuthi ibethelwe ngokuthe ngqo kwiinxalenye ngabathengi.Emva kokuba i-beryllium bronze iphathwe ngeenkqubo ezahlukeneyo, oonobumba be-alloy state eYurophu nase-United States zezi: A imele isisombululo esiqinileyo i-annealed state.I-alloy ikwimo ethambileyo kwaye kulula ukuyilwa ngokufaka isitampu.Ifuna ukuqhubeka nokusebenza okubandayo okanye ukuguga ngokuthe ngqo ukomeleza unyango.H imele imo yokusebenza nzima (nzima).Thatha iphepha eliqengqelekayo elibandayo njengomzekelo, i-37% yesidanga sokusebenza esibandayo sigcwele imo enzima (H), i-21% yesidanga sokusebenza esibandayo yi-semi hard state (1/2H), kunye ne-11% yesidanga sokusebenza esibandayo yi-1 /4 imeko enzima (1/4H).Abasebenzisi bangakhetha imo efanelekileyo ethambileyo kunye nobunzima ngokobunzima bemilo yamalungu aza kubethwa.I-T ibhekisela kunyango lokushisa emva kokuguga.Ukuba inkqubo yokuguqulwa kunye nokuguga ukomelezwa okupheleleyo kwamkelwe, imeko yayo imelwe yi-HT.
