Ungakanani obona bunzima bufanelekileyo bokucima i-beryllium yobhedu
Ngokuqhelekileyo, ubunzima be-beryllium yobhedu abuchazwanga ngokungqongqo, kuba emva kwe-beryllium isisombululo esiqinileyo sobhedu kunye nonyango lokuguga, phantsi kweemeko eziqhelekileyo, kuya kubakho imvula encinci yesigaba esiqinileyo ixesha elide, ngoko siya kufumanisa ukuba i-beryllium yobhedu iyakhula. kunye nexesha.Isenzeko sokuba ukuqina kwayo kwandisa kunye nexesha.Ukongezelela, izinto ezi-elastic zincinci kakhulu okanye zincinci kakhulu, kwaye kunzima ukulinganisa ubunzima, ngoko ke uninzi lwazo lulawulwa ngeemfuno zenkqubo.Ngezantsi lulunye ulwazi lwereferensi yakho.
Unyango lobushushu be-beryllium yobhedu
I-beryllium bronze yi-alloy ene-versatile overcipitation hardening alloy.Emva kwesisombululo kunye nonyango lokuguga, amandla anokufikelela kwi-1250-1500MPa (1250-1500kg).Iimpawu zayo zonyango lobushushu zezi: emva konyango lwesisombululo, ineplastiki elungileyo kwaye inokukhubazeka ngokusebenza okubandayo.Nangona kunjalo, emva konyango lokuguga, unomda obalaseleyo we-elastic, kwaye ukuqina kunye namandla nawo aphuculwe.
(1) Isisombululo sonyango lwe-beryllium yobhedu
Ngokubanzi, ubushushu bobushushu bonyango lwesisombululo buphakathi kwe-780-820 °C.Kwizinto ezisetyenziswa njengezinto ezilastiki, i-760-780 ° C isetyenziswa, ikakhulu ukuthintela iinkozo ezirhabaxa ekuchaphazeleni amandla.Ubushushu obufanayo kwiziko lonyango lwesisombululo kufuneka ilawulwe ngokungqongqo ngaphakathi ± 5℃.Ixesha lokubamba lingabalwa ngokubanzi njengeyure eli-1 / 25mm.Xa i-bronze ye-beryllium iphantsi kwesisombululo sokufudumala kwonyango emoyeni okanye kwi-oxidizing atmosphere, ifilimu ye-oxide iya kwenziwa phezu komhlaba.Nangona inempembelelo encinci kwiimpawu zomatshini emva kokuqiniswa kokuguga, kuya kuchaphazela ubomi benkonzo yesixhobo ngexesha lokusebenza kubanda.Ukuze ugweme i-oxidation, kufuneka itshiswe kwisithando somlilo okanye ukuchithwa kwe-ammonia, igesi engasebenziyo, i-atmospheric yokunciphisa (njenge-hydrogen, i-carbon monoxide, njl.), ukwenzela ukuba ufumane umphumo wokushisa oqaqambileyo.Ukongezelela, ingqalelo kufuneka ihlawulwe ekunciphiseni ixesha lokudlulisa kangangoko kunokwenzeka (kule meko yokucima), ngaphandle koko kuya kuchaphazela iimpawu zomatshini emva kokuguga.Izinto ezinqabileyo akufanele zidlule imizuzwana emi-3, kwaye iindawo eziqhelekileyo akufanele zidlule imizuzwana emi-5.Indawo yokucima ngokuqhelekileyo isebenzisa amanzi (akukho mfuneko zokufudumeza), ngokuqinisekileyo, iinxalenye ezinemilo enzima nazo zinokusebenzisa ioli ukuphepha ukuguquka.
(2) Ukuguga unyango lwe-beryllium bronze
Ukushisa okuguga kwe-beryllium yobhedu kuhambelana nomxholo we-Be, kwaye zonke ii-alloys eziqulethe ngaphantsi kwe-2.1% ye-Be kufuneka zibe zikhulile.Kwi-alloys ene-Be mkhulu kune-1.7%, iqondo lokushisa eliphezulu lokuguga li-300-330 ° C, kwaye ixesha lokubamba liyi-1-3 iiyure (kuxhomekeke kwimilo kunye nobukhulu becala).I-alloys ye-electrode conductivity ephezulu kunye ne-Be ngaphantsi kwe-0.5%, ngenxa yokunyuka kwendawo yokunyibilika, ubushushu obuphezulu bokuguga yi-450-480 ℃, kwaye ixesha lokubamba liyi-1-3 iiyure.Kwiminyaka yakutshanje, ukuguga okuphindwe kabini kunye nokuguga kwamanqanaba amaninzi kuye kwaphuhliswa, oko kukuthi, ukuguga kwexesha elifutshane kwiqondo lokushisa eliphezulu kuqala, kwaye emva koko ukuguga kwexesha elide kwiqondo lokushisa eliphantsi.Inzuzo yale nto kukuba ukusebenza kuphuculwe kodwa inani le-deformation liyancitshiswa.Ukuze kuphuculwe ukuchaneka komda we-beryllium yobhedu emva kokuguga, i-clamp clamping ingasetyenziselwa ukuguga, kwaye ngamanye amaxesha unyango oluhlukeneyo lokuguga lunokusetyenziswa.
(3) Unyango loxinzelelo lwe-beryllium bronze
I-Beryllium yobhedu yokunciphisa uxinzelelo lweqondo lokushisa yi-150-200 ℃, ixesha lokubamba yi-1-1.5 iiyure, ezinokusetyenziswa ukuphelisa uxinzelelo olushiyekileyo olubangelwa kukusika kwesinyithi, ukulungiswa, ukubumba okubandayo, njl. ngexesha lokusetyenziswa kwexesha elide.
Ubhedu lwe-beryllium kufuneka luphathwe ubushushu kwi-HRC 30 degrees.Ifanele iphathwe njani?
Beryllium Bronze
Kukho amabakala amaninzi, kwaye ubushushu bokuguga buhlukile.Andingomenzi oqeqeshiweyo wobhedu lweberyllium, kwaye andiyazi.Ndajonga incwadana.
1. Ukushisa kwesisombululo se-beryllium yobhedu ephezulu yi-760-800 ℃, kunye nokushisa kwesisombululo se-high-conductivity beryllium-copper yi-900-955℃.Icandelo elincinci kunye nelincinci ligcinwe imizuzu emi-2, kwaye icandelo elikhulu akufanele lidlule imizuzu engama-30.Isantya sokufudumeza silula kwaye sikhawuleza.kade,
2. Emva koko ufezekise ukucima, ixesha lokudluliselwa kufuneka libe lifutshane, kwaye isantya sokupholisa kufuneka sikhawuleze ukuphepha imvula yesigaba sokuqinisa kwaye sichaphazele unyango olulandelayo lokuqiniswa kokuguga.
3. Ukuguga ukuguga, ubushushu bokuguga bobhedu beryllium obuphezulu bungama-260-400 ℃, kunye nokugcinwa kobushushu yimizuzu eyi-10-240, kunye nokushisa okuguga kwe-high-conductivity beryllium yobhedu yi-425-565 ℃, kunye nexesha lokubamba. yimizuzu engama-30-40;Ngokuhamba kwexesha, le yangaphambili inokulungiswa, ngelixa le yokugqibela ayikwazi ukulungiswa.Kuyimfuneko ukuqalisa kwakhona kwisisombululo esiqinileyo kwakhona.
Ubushushu obukhankanyiweyo buthamba ngaphezulu kobushushu bokwaluphala, akunjalo?Ngoko ke, umphumo wesisombululo oqinileyo woqobo utshatyalalisiwe.Andazi ukuba iqondo lobushushu lithini na.Emva koko qalisa kuphela kwisisombululo esiqinileyo kwakhona.Into ephambili kukuba kufuneka ukwazi uhlobo lwe-beryllium yobhedu, isisombululo esiqinileyo kunye nenkqubo yokuguga yobhedu oluhlukeneyo lwe-beryllium lusahluka, okanye udibane nomenzi wezinto eziphathekayo malunga nendlela yokushisa ngokuchanekileyo unyango.
Indlela yokutshisa unyango lwe-bronze yesikhumba
Ubhedu lwesikhumba?Kufuneka iberyllium ubhedu, akunjalo?Ukomeleza ukunyangwa kobushushu be-beryllium yobhedu ngokuqhelekileyo kunyango lwesisombululo + ukuguga.Unyango lwesisombululo luyahluka ngokwe-beryllium bronze ethile kunye neemfuno ezithile zobugcisa becandelo.Kwiimeko eziqhelekileyo, ukufudumeza kwi-800 ~ 830 degrees kusetyenziswa.Ukuba isetyenziswe njenge-elastic element, ubushushu bokufudumala yi-760 ~ 780.Ngokobunzima obusebenzayo beengxenye, ukufudumeza kunye nexesha lokubamba likwahluke.Ingxaki ethile ihlalutywa ngokweenkcukacha, ngokuqhelekileyo i-8 ~ 25 imizuzu.Ukushisa okuguga ngokuqhelekileyo malunga ne-320. Ngokufanayo, iimfuno ezithile ziyahluka ngokweempawu zomatshini zamacandelo.Ixesha lokuguga liyi-1 ukuya kwiiyure ze-2 kwiindawo ezinobunzima kunye nokuxhatshazwa kokugqoka, kunye neeyure ezi-2 ukuya kwezi-3 kwiindawo ezinokuqina.Yure.
Inkqubo ethile kufuneka ihlengahlengiswe ngokweenxalenye ezahlukeneyo ze-beryllium bronze, imilo kunye nobukhulu beendawo, kunye neemfuno zokugqibela zempahla.Ukongezelela, ukufudumeza kwe-beryllium bronze kufuneka kusebenzise umoya okhuselekileyo okanye unyango lwe-vacuum.I-atmospheres esetyenziswa ngokuqhelekileyo yokukhusela ibandakanya umphunga, i-ammonia, i-hydrogen okanye i-charcoal, kuxhomekeke kwiimeko ezithile zendawo yakho.
Buphathwa njani ubushushu bobhedu beberyllium?
I-Beryllium yobhedu yinto eguquguqukayo kakhulu yemvula eyenza lukhuni i-alloy.Emva kwesisombululo kunye nonyango lokuguga, amandla anokufikelela kwi-1250-1500MPa.Iimpawu zayo zonyango lobushushu zezi: emva konyango lwesisombululo, ineplastiki elungileyo kwaye inokukhubazeka ngokusebenza okubandayo.Nangona kunjalo, emva konyango lokuguga, unomda obalaseleyo we-elastic, kwaye ukuqina kunye namandla nawo aphuculwe.
Unyango olushushu lwe-beryllium yobhedu lunokwahlulwa lube unyango lwe-annealing, unyango lwesisombululo kunye nonyango lokuguga emva konyango lwesisombululo.
Ukubuyisela (ukubuyisela) unyango lomlilo lohlulwe lube:
(1) Ukuthambisa okuphakathi kokuthambisa, okunokusetyenziswa njengenkqubo yokuthambisa kumbindi wokusetyenzwa.
(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.
Unyango olushushu lwe-Berryllium Bronze kwiTekhnoloji yoNyango loBushushu
I-beryllium bronze yi-alloy ene-versatile overcipitation hardening alloy.Emva kwesisombululo kunye nonyango lokuguga, amandla anokufikelela kwi-1250-1500MPa (1250-1500kg).Iimpawu zayo zonyango lobushushu zezi: emva konyango lwesisombululo, ineplastiki elungileyo kwaye inokukhubazeka ngokusebenza okubandayo.Nangona kunjalo, emva konyango lokuguga, unomda obalaseleyo we-elastic, kwaye ukuqina kunye namandla nawo aphuculwe.
