I-Beryllium yethusi njenge-castable wrought alloy beryllium copper alloy, eyaziwa nangokuthi i-beryllium bronze, i-beryllium copper alloy.Kuyingxubevange enezakhiwo ezinhle ezihlanganisa imishini, ngokomzimba namakhemikhali.Ngemuva kokucisha nokushisa, inamandla aphezulu, ukuqina, ukumelana nokugqoka, ukumelana nokukhathala nokumelana nokushisa.Ngesikhathi esifanayo, ithusi le-beryllium libuye libe ne-conductivity ephezulu kagesi., i-thermal conductivity, ukumelana nokubanda kanye nokungezona uzibuthe, azikho izinhlansi uma zithintekile, kulula ukushisela futhi ziqine, ukumelana nokugqwala okuhle kakhulu emkhathini, amanzi ahlanzekile namanzi olwandle.
Kuyinto esezingeni eliphezulu enwebekayo esebenza kahle kakhulu phakathi kwama-alloys ethusi.Inamandla aphezulu, ukunwebeka, ubulukhuni, amandla okukhathala, ukunwebeka okuncane, ukumelana nokugqwala, ukumelana nokugqokwa, ukumelana nokubanda, ukuhamba okuphezulu, okungezona uzibuthe, futhi azikho izinhlansi uma zithinteka.Uchungechunge lwezakhiwo ezinhle kakhulu zomzimba, zamakhemikhali nezomshini.Umbala wethusi we-beryllium ngokuvamile ubonisa imibala emibili ebomvu noma ephuzi.Kuyinto evamile ukuthi umbala wethusi we-beryllium ubonakale uphuzi futhi ubomvu, ngoba ukusabela kwamakhemikhali we-oxidation kwenzeka ngesikhathi sokukhiqiza nokugcina inqubo, futhi umbala uyashintsha.
Amapharamitha: Ukuminyana 8.3g/cm3 Ukuqina ngaphambi kokucisha 200-250HV Ukuqina ngemva kokucisha ≥36-42HRC Ukushisa kokucisha 315℃≈600℉ Isikhathi sokucisha amahora angu-2
Ukushisa okuthambisayo okungu-930℃ Ngemva kokuthambisa, ubulukhuni 135±35HV, amandla aqinile ≥1000mPa
I-Beryllium yethusi ihlukaniswe ngethusi eliphezulu le-beryllium kanye nethusi eliphansi le-beryllium.Ikhopha ye-beryllium ephezulu isho ithusi le-beryllium elinokuqukethwe kwe-beryllium okukhulu kuno-2.0.I-Beryllium yethusi iyinsimbi yokumelana ne-welding electrode yokushisela, ene-conductivity enhle kagesi kanye ne-thermal kanye nobulukhuni obuphezulu.Lapho ushisela, ukugqoka kwe-electrode kuncane, isivinini siyashesha, futhi izindleko ziphansi.
Inqubo Yokukhiqiza I-Beryllium Copper
Inqubo yokukhiqiza i-beryllium yethusi ihlukaniswe ngezinyathelo ezine: ukukhiqizwa kwe-beryllium-copper master alloy ngendlela yokunciphisa i-carbothermal, ukuncibilikiswa kwe-beryllium ingxube yethusi, i-ingot ye-alloy yethusi kanye nokukhiqizwa kwepuleti le-beryllium yethusi, i-strip kanye ne-strip.
Ukukhiqizwa kwe-beryllium-copper master alloys ngokunciphisa i-carbothermal kubhekisela ekunciphiseni okuqondile kwe-beryllium ku-beryllium oxide ne-carbon ethusi elincibilikisiwe, kulandelwa i-alloying yethusi.Ukukhiqizwa kwe-beryllium-copper master alloy ngokunciphisa i-carbothermic embonini kwenziwa esithandweni somlilo se-arc kagesi.Isithando somlilo se-arc sikagesi sifakwa esitsheni esivaliwe.Umsebenzisi ugqoke imaski yegesi.I-% ye-carbon powder ixutshwa emshinini webhola kanye nomhlabathi, bese ungqimba lwethusi, ungqimba lwe-beryllium oxide nengxube ye-carbon powder ilayishwa esithandweni sogesi se-arc ngamaqoqo, anikwe amandla futhi ancibilike.Uma selehlile ku-950 degrees Celsius - 1000 degrees Celsius, igama lengxubevange elithi beryllium carbide, carbon, kanye nempushana eyinsalela iyantanta, i-slag, bese iphonswa kuma-ingots angu-2.25 kg noma ama-5 kg ​​ku-950 degrees Celsius.
Inkokhelo esetshenziswa ekuncibilikiseni ingxubevange ye-beryllium yethusi ihlanganisa insimbi entsha, izicucu, ishaja yesibili yokuncibilikisa kanye nengxubevange enkulu.
I-Berryllium ngokuvamile isebenzisa i-beryllium-copper master alloy (equkethe i-beryllium 4%);i-nickel ngezinye izikhathi isebenzisa insimbi entsha, okungukuthi, i-nickel electrolytic, kodwa kungcono ukusebenzisa i-nickel-copper master alloy (equkethe i-nickel engu-20%);i-cobalt isebenzisa i-cobalt-copper master alloy (Cobalt 5.5%), kanti abanye basebenzisa ngokuqondile i-cobalt ehlanzekile;i-titanium yengezwa nge-titanium-copper master alloy (equkethe i-titanium engu-15%, kanti enye iqukethe ne-27.4% ye-titanium), kanti enye yengeza ngokuqondile i-sponge titanium;i-magnesium iyi-magnesium- I-Copper master alloy (equkethe u-35.7% we-magnesium) yengeziwe.
Ama-chips (ama-chips okugaya, ama-cutting chips, njll.) kanye nezinsalela zekhona ezincane ezikhiqizwa ngesikhathi sokucubungula ngokuvamile ziphonswa kuma-ingots ngemva kokuncibilika kwesibili njengeshaja yokuncibilikisa;ngaphezu kwento evuselelwe kabusha yokuncibilika, lapho i-batching Kuvamile futhi ukwengeza imfucuza yokulahla kanye nemfucuza yomshini ngqo esithandweni.
Ingot ye-beryllium copper alloy ihlukaniswe yaba ingot engeyona i-vacuum ne-vacuum ingot.Izindlela zokuphonsa ingot ye-non-vacuum okwamanje ezisetshenziswa ekukhiqizeni i-beryllium yethusi i-alloy alloy zihlanganisa ukufakwa kwe-ingot yensimbi ethambekele, ukuphonsa ingot okugelezayo, ukuphonsa ingot okungapheli kanye nokusakazwa kwe-ingot okuqhubekayo.Izindlela ezimbili zokuqala zisetshenziswa kuphela ezimbonini ezinezikali zokukhiqiza ezincane.
Ochwepheshe bathi ukuze kutholwe ama-ingots e-beryllium-copper alloy ane-gas ephansi, ukuhlukaniswa okuncane, ukufakwa okuncane, kanye nesakhiwo sekristalu esifana nesinye nesiminyene, indlela engcono kakhulu yokukhipha i-ingots ngemva kokuncibilika kwe-vacuum.Ukusakaza ingot ye-vacuum kunomthelela obalulekile ekuqinisekiseni okuqukethwe kwezinto ezi-oxidizable kalula njenge-beryllium ne-titanium.Uma kudingekile, igesi ye-inert ingasethulwa ukuze kuvikelwe inqubo yokukhipha ingot.
Incazelo yokwelashwa kokushisa kwethusi kwe-beryllium: ukwelashwa kokushisa kwe-beryllium yethusi Ukwelashwa kokushisa kwe-beryllium bronze kungahlukaniswa ngokwelashwa kwe-annealing, ukwelashwa kwesisombululo kanye nokwelashwa kokuguga ngemva kokwelashwa kwesisombululo.
Ukwelashwa kwe-beryllium copper retreat (return) kuhlukaniswe: (1) Ukuthambisa okuphakathi nendawo, okungase kusetshenziselwe inqubo yokuthambisa phakathi nokucubungula.(2) Ukushisa okuzinzile kusetshenziselwa ukuqeda ukucindezelwa komshini okukhiqizwa ngesikhathi sokunemba kwemithombo nokulinganisa, kanye nokuzinzisa ubukhulu bangaphandle.(3) Ukunciphisa ingcindezi kusetshenziselwa ukuqeda ingcindezi yomshini ekhiqizwa ngesikhathi somshini nokulinganisa.
