Inkqubo yonyango lobushushu lweCu-Be ingxubevange yonyango lobushushu lucime ukucima kunye nokuqina kweminyaka.Ngokungafaniyo nezinye ingxubevange zobhedu amandla abo afunyanwa kuphela umzobo ebandayo, beryllium ekhandiweyo ifunyenwe umzobo ebandayo kunye thermal yobudala lukhuni iinkqubo zokusebenza ukuya 1250 ukuya 1500 MPa.Ukuqina kweminyaka ngokuqhelekileyo kubhekiselwa kuko njengokuqina kwemvula okanye inkqubo yonyango lobushushu.Ikhono le-beryllium copper alloy ukwamkela olu hlobo lwenkqubo yonyango lokushisa lungcono kunezinye i-alloys ngokwemigaqo yokuqulunqa kunye nokusebenza kwezixhobo zokusebenza.Ngokomzekelo, iimilo eziyinkimbinkimbi zinokufezekiswa kumanqanaba aphezulu kunye namandla azo zonke ezinye ii-alloys ezisekelwe kubhedu, oko kukuthi, phantsi kwe-cold rolling kunye nokuguga okulandelayo kwezinto eziluhlaza.

Iyonke inkqubo yobudala yokuqina kokuqina okuphezulu kobhedu lwe-beryllium alloy C17200, inkqubo yayo ekhethekileyo yonyango lobushushu lokubumba kunye ne-alloys yokubumba, iziko lombane elicetyiswayo kakhulu lonyango lobushushu, i-oxidation yomoya ongaphezulu kunye nesiseko sonyango lobushushu kunye neendlela zokucima zichazwe ngokweenkcukacha. ngezantsi.

Kuyo yonke inkqubo yokuguga yokuqina, iincinci ze-beryllium ezinoqoqosho zangaphandle ziya kuveliswa kwi-substrate yokulima izinto zetsimbi, ezibonakalisa ukulawula ukusabalalisa, kwaye amandla ayo aya kutshintsha kunye nexesha lokuguga kunye nokushisa.Elona xesha licetyiswayo loMgangatho waMazwe ngaMazwe kunye noBushushu livumela iinxalenye ukuba zifikelele kumandla azo aphezulu kwiiyure ezimbini ukuya kwezintathu ngaphandle kokubeka esichengeni amandla ngokuba sesichengeni sobushushu ixesha elide.Ngokomzekelo, igrafu yempendulo ye-alloy ye-C17200 kumzobo ibonisa indlela ubushushu obuphantsi kakhulu, ubushushu obuqhelekileyo kunye nobushushu obuphezulu bokuguga bubeka esichengeni iipropati ze-alloy kunye nexesha elithathayo ukufezekisa amandla aphezulu.

Inokubonwa kumfanekiso ukuba kwiqondo lokushisa eliphantsi kakhulu le-550 ° F (290 ° C), amandla e-C17200 akhula ngokukhawuleza, kwaye akafikeleli kwixabiso eliphezulu kude kube malunga neeyure ezingama-30 kamva.Kwiqondo lokushisa eliqhelekileyo le-600 ° F (315 ° C) kwiiyure ze-3, ukuguqulwa kokuqina kweC17200 akukhulu.Kwi-700 ° F (370 ° C), ukuqina kufikelela kwimizuzu engamashumi amathathu kwaye kuncipha ngokukhawuleza.Ukuyibeka ngokulula, njengoko ukushisa okuguga kukhula, ixesha elifunekayo ukufezekisa amandla aphezulu kunye namandla aphezulu angasetyenziswa aya kuncipha.

I-C17200 i-beryllium yobhedu inokugqithwa ngamandla ahlukeneyo.Incopho ye-embrittlement ibhekisa kwi-embrittlement efumana amandla amakhulu.Ii-alloys ezingadalanga ukuya kumandla aphezulu azigugi, kwaye ii-alloys ezidlula amandla azo aphezulu zidlulile.I-embrittlement enganeleyo ye-beryllium iphucula i-ductility, i-uniform elongation kunye namandla okukhathala, ngelixa i-embrittlement eninzi iphucula ukuhanjiswa kombane, ukuhanjiswa kobushushu kunye nokuthembeka kwe-gauge.I-Beryllium Beryllium ayifaki ukushisa kwegumbi nokuba igcinwe ixesha elide.

Ukunyamezela ixesha lokuqina kweminyaka kuxhomekeke kulawulo lobushushu kunye neenkcukacha zokugqibela zepropati.Ukuze kuphunyezwe ngcono elona xesha lilungileyo lesicelo kwiqondo lobushushu eliqhelekileyo, ixesha lokunyibilika kwesithando somlilo lilawulwa ngokubanzi phakathi kwemizuzu eyi-±30.Nangona kunjalo, ukunyuswa kobushushu obuphezulu, ukuphindaphindwa kwewotshi echaneke ngakumbi kuyafuneka ukunqanda umyinge.Umzekelo, qiniseka ukuba ulawula ixesha lokuqhawula i-C17200 kwi-700 ° F (370 ° C) ukuya kwi-± 3 imizuzu yokugcina ukusebenza kakuhle.Ngokufanayo, ngenxa yokuba i-curve yempendulo ye-embrittlement iphuculwe kakhulu kwikhonkco yasekuqaleni, iinguqu ezizimeleyo zenkqubo yonke kufuneka zilawulwe ngokungqongqo kwi-embrittlement eyaneleyo.Ngexesha lomjikelo wobunzima obuchaziweyo, amazinga okufudumeza kunye nokupholisa awabalulekanga.Nangona kunjalo, ukuze kuqinisekiswe ukuba inxalenye ayinakunyanzelwa ukuba i-embrittlement ngokuthe ngcembe ide ifike kwiqondo lokushisa, i-resistor ye-thermal inokubekwa ukuze inqume xa ubushushu obufunekayo bufezekiswa.

Ubudala oomatshini kunye nezixhobo zokusebenza nzima

Inkqubo yokujikeleza iziko legesi.Iziko legesi lenkqubo yokujikeleza liqondo lobushushu elilawulwa ku ±15°F (±10°C).Kucetywa ukuba kuqhutywe isisombululo esiqhelekileyo sokuqina kweminyaka kwiindawo zobhedu ze-beryllium.Eli ziko lenzelwe ukuhlalisa zombini ivolumu ephezulu kunye nenani eliphantsi kwaye lilungele ukuvavanya iindawo zokufa kwimidiya enqabileyo.Nangona kunjalo, ngenxa yomgangatho wayo we-thermal, kubalulekile ukuthintela ukungonelanga kwe-embrittlement okanye ixesha elifutshane kakhulu lomjikelo we-embrittlement kwiindawo ezisemgangathweni.

Chain uhlobo embrittlement eziko.Iziko zokuguga ze-Strand ezinomoya okhuselayo njengento yokufudumeza zifanelekile ukuveliswa kunye nokucutshungulwa kweekhoyili ezininzi ze-beryllium zobhedu ngokubanzi kwisithando somlilo eside, ukwenzela ukuba izinto eziluhlaza zinokwandiswa okanye zihlanganiswe.Oku kuvumela ulawulo olungcono lwexesha kunye nobushushu, kuthintela i-symmetry inxalenye, kwaye inokusingatha ixesha elikhethekileyo lokungonelanga okanye ukushisa okuphezulu / ukuguga okufutshane kunye nokuqina okukhethiweyo.

Ukuhlamba ityuwa.Kwakhona kucetywayo ukuba kusetyenziswe ibhafu yetyuwa kwi-age-hard-harding ye-beryllium copper alloys.Ukuhlamba ityuwa kunokubonelela ngokukhawuleza kunye nokufudumeza okufanayo kwaye kunconywa ukuba kusetyenziswe kuzo zonke iindawo zokushisa ukushisa, ngokukodwa kwimeko yokushisa okuphezulu kwi-embrittlement kwixesha elifutshane.

Isithando somlilo.I-vacuum imbrittlement yepompo ye-beryllium yobhedu inokwenziwa ngempumelelo, kodwa lumka.Ngenxa yokuba ukufudumeza kwesithando somlilo kusetyenziswa kuphela umthombo wemitha, kunzima ukufudumeza ngokufanayo iindawo ezithwele kakhulu.Amalungu alayisha ngaphandle agqithise ngokukhawuleza kunamalungu angaphakathi, ngoko intsimi yeqondo lokushisa emva kwenkqubo yokunyanga ukushisa iya kutshintsha ukusebenza.Ukuze kuqinisekiswe ngcono ukufudumeza okufanayo, umthwalo kufuneka ukhawulelwe, kwaye iinxalenye kufuneka zikhuselwe kwi-solenoid yokufudumala.Isithando somlilo singasetyenziselwa ukugcwalisa umva ngeegesi ezinqabileyo ezifana ne-argon okanye i-N2.Ngokufanayo, ngaphandle kokuba i-furnace ixhotyiswe nge-fan yokupholisa inkqubo yokujikeleza, qiniseka ukugcina iindawo.
