Inqubo yokwelapha ukushisa ye-Cu-Be ingxubevange iwukuqeda ukushisa kokushisa kanye nokwenza lukhuni ubudala.Ngokungafani namanye ama-alloys ethusi amandla awo atholakala kuphela ngokudweba okubandayo, i-beryllium eyenziwe itholakala ngokudweba okubandayo kanye nezinqubo zokusebenza eziqinile zokushisa kuze kufike ku-1250 kuya ku-1500 MPa.Ukuqina kweminyaka ngokuvamile kubizwa ngokuthi ukuqina kwemvula noma inqubo yokwelapha ukushisa.Ikhono le-beryllium i-copper alloy ukwamukela lolu hlobo lwenqubo yokwelashwa kokushisa lungcono kunamanye ama-alloys ngokusebenza kokwenza kanye nokusebenza kwemishini.Isibonelo, izimo eziyinkimbinkimbi zingafinyelelwa kumazinga aphezulu wamandla namandla awo wonke amanye ama-alloys asekelwe ethusi, okungukuthi, ngaphansi kokugoqa okubandayo nokuguga okulandelayo kwempahla eluhlaza.

Yonke inqubo yobudala yokuqina kokuqina kwe-copper beryllium alloy C17200, inqubo yayo ekhethekile yokwelashwa kokushisa yokubumba nokubumba ama-alloys, isithando somlilo esinconywa kakhulu sokwelapha ukushisa, i-oxidation yomoya ongaphezulu kanye nezindlela zokushisa eziyisisekelo nezindlela zokucisha zichazwe ngokuningiliziwe. ngezansi.

Kuyo yonke inqubo yokuguga kokuqina, izinhlayiya ezicebile ze-beryllium ezinomnotho zangaphandle zizokhiqizwa endaweni engaphansi yokulima impahla yensimbi, okuwumfanekiso wokulawula ukusabalalisa, futhi amandla ayo azoshintsha ngokuhamba kwesikhathi kanye nezinga lokushisa.Isikhathi Esijwayelekile Samazwe Ngamazwe Nezinga Lokushisa esinconywa kakhulu sivumela izingxenye ukuthi zifinyelele amandla azo aphezulu phakathi kwamahora amabili noma amathathu ngaphandle kokuphazamisa amandla ngokuchayeka isikhathi eside kumazinga okushisa.Isibonelo, igrafu yempendulo ye-alloy ye-C17200 esithombeni ibonisa ukuthi izinga lokushisa eliphansi kakhulu, izinga lokushisa elijwayelekile kanye nezinga lokushisa eliphezulu lokuguga libeka engcupheni izici eziphezulu ze-alloy kanye nesikhathi esisithathayo ukuze kuzuzwe amandla aphezulu.

Kungabonakala esithombeni ukuthi ekushiseni okuphansi kakhulu kwe-550 ° F (290 ° C), amandla e-C17200 akhula kancane, futhi angafinyeleli inani eliphakeme kakhulu kuze kube ngamahora angu-30 kamuva.Ezingeni lokushisa elijwayelekile lika-600 ° F (315 ° C) amahora angu-3, ​​ukuguqulwa kokuqina kwe-C17200 akukukhulu.Ku-700°F (370°C), ukuqina kuphakama phakathi nemizuzu engamashumi amathathu futhi kuncipha kakhulu ngokushesha.Ukukubeka kalula, njengoba izinga lokushisa lokuguga likhuphuka, isikhathi esidingekayo ukuze kuzuzwe amandla aphezulu kanye namandla amakhulu angasetshenziswa azokwehla.

I-C17200 i-beryllium yethusi ingahlanganiswa ngamandla ahlukene.I-embrittlement peak ibhekisela ku-embrittlement ezuza amandla amakhulu.Ama-alloys angagugi kuze kube namandla amakhulu awagugi, futhi ama-alloys angaphezu kwamandla awo aphezulu asekhulile.I-embrittlement enganele ye-beryllium ithuthukisa i-ductility, i-uniform elongation namandla okukhathala, kuyilapho i-embrittlement eningi ithuthukisa ukuqhutshwa kukagesi, ukudluliswa kokushisa nokuthembeka kwegeji.I-Beryllium Beryllium ayifaki izinga lokushisa ekamelweni ngisho noma igcinwe isikhathi eside.

Ukubekezelela isikhathi sokuqina kweminyaka kulele ekulawuleni izinga lokushisa kanye nencazelo yokugcina yendawo.Ukuze kuzuzwe kangcono isikhathi sokufaka isicelo esingcono kakhulu ekushiseni okujwayelekile, isikhathi sesithando somlilo esincibilika ngokuvamile silawulwa phakathi kwamaminithi angu-±30.Kodwa-ke, ukuze izinga lokushisa eliphakeme likhuphuke, imvamisa yewashi enembe kakhudlwana iyadingeka ukuvimbela isilinganiso.Isibonelo, qiniseka ukuthi ulawula isikhathi se-embrittlement se-C17200 ku-700°F (370°C) sibe phakathi kwamaminithi angu-±3 ukuze ugcine ukusebenza okuphezulu.Ngokufanayo, ngenxa yokuthi ijika lokuphendula le-embrittlement lithuthukisiwe kakhulu kusixhumanisi sokuqala, okuguquguqukayo okuzimele kwenqubo yonke kufanele futhi kulawulwe ngokuqinile ukuze kutholakale i-embrittlement enganele.Phakathi nesikhathi somjikelezo wokuqina wobudala obushiwo, amazinga okushisa nawokupholisa awabalulekile.Nokho, ukuze kuqinisekiswe ukuthi ingxenye ayithambekele ekungeneni kancane kancane kuze kufike izinga lokushisa, kungabekwa isivikelo esishisayo ukuze kunqunywe ukuthi izinga lokushisa elifunwayo lifinyelelwa nini.

Imishini yokuqinisa iminyaka yobudala kanye nemishini

Isithando somlilo segesi esijikelezayo.I-circulating system gas furnace izinga lokushisa lilawulwa ku-±15°F (±10°C).Kuhlongozwa ukwenza isixazululo esijwayelekile sokuqina kweminyaka sezingxenye zethusi ze-beryllium.Lesi sithando somlilo siklanyelwe ukuthwala izingxenye zevolumu ephezulu kanye nevolumu ephansi futhi silungele ukuhlola izingxenye zokufa zokugxiviza kumidiya ephukile.Kodwa-ke, ngenxa yekhwalithi yayo eshisayo, kubalulekile ukuvimbela ukuvuthwa okunganele noma izikhathi zomjikelezo we-embrittlement emifushane kakhulu ezingxenyeni zekhwalithi.

Uhlobo lwe-chain embrittlement isithando somlilo.Izithando zokuguga ze-Strand ezinomoya wokuzivikela njengento yokushisa zifaneleka ukukhiqizwa nokucutshungulwa kwamakhoyili ethusi amaningi e-beryllium ngokuvamile esithandweni somlilo eside, ukuze impahla eluhlaza inganwetshwa noma ihlanganiswe.Lokhu kuvumela ukulawula okungcono kwesikhathi nezinga lokushisa, kuvimbela ukulinganisa okuncane, futhi kungaphatha izikhathi ezikhethekile zokushisa okunganele noma okuphezulu/ukuguga okufushane kanye nokuqina okukhethekile.

Ukugeza usawoti.Kuphinde kuhlongozwe ukuthi kusetshenziswe ibhavu likasawoti ekwelapheni ukuqina kweminyaka yama-alloys ethusi e-beryllium.Amabhati kasawoti anganikeza ukushisa okusheshayo nokufana okufanayo futhi kunconywa ukuthi kusetshenziswe kuzo zonke izindawo eziqinile zokushisa, ikakhulukazi esimweni sokushisa okuphezulu kwe-embrittlement ngesikhathi esifushane.

Isithando somlilo.I-vacuum futha ebrittlement yezingxenye zethusi ze-beryllium ingenziwa ngempumelelo, kodwa qaphela.Ngenxa yokuthi ukushisisa kwesithando somlilo kungokusebenzisa umthombo wemisebe kuphela, kunzima ukushisisa ngokufanayo izingxenye ezilayishwe kakhulu.Izingxenye ezilayisha ngaphandle zikhishwa ngokushesha kunezingxenye zangaphakathi, ngakho-ke inkambu yokushisa ngemva kwenqubo yokwelapha ukushisa izoshintsha ukusebenza.Ukuze kuqinisekiswe kangcono ukushisa okufanayo, umthwalo kufanele ube nomkhawulo, futhi izingxenye kufanele zivikelwe ekushiseni kwe-solenoid.Isithando somlilo singasetshenziselwa ukugcwalisa ngemuva ngamagesi angavamile njenge-argon noma i-N2.Ngokufanayo, ngaphandle uma isithando somlilo sifakwe isiphephetha-moya sokupholisa isistimu ejikelezayo, qiniseka ukuthi ugcina izingxenye.
