Kafin, abokan ciniki da yawa sun tambayi abokan aiki daga Sashen Fasaha na RSM game da gami da titanium.Yanzu, Ina so in taƙaita muku abubuwan da ke gaba game da abin da aka yi da ƙarfe titanium alloy.Ina fatan za su iya taimaka muku.
Titanium alloy wani abu ne da aka yi da titanium da sauran abubuwa.
Titanium crystal ne mai kama da juna, tare da ma'aunin narkewar 1720 ℃.Lokacin da zafin jiki ya yi ƙasa da 882 ℃, yana da tsarin shinge mai hexagonal kusa da shi, wanda ake kira α Titanium;Yana da tsari mai siffar siffar jiki a tsakiya sama da 882 ℃, wanda ake kira β Titanium.Yin amfani da halaye daban-daban na sifofi biyu na sama na titanium, ana ƙara abubuwan gami da suka dace don canza yanayin yanayin canjin lokaci a hankali da abun ciki na lokaci don samun alloys titanium tare da sifofi daban-daban.A cikin zafin jiki, titanium alloys suna da nau'ikan tsarin matrix iri uku, haka nan kuma an raba alloys titanium zuwa kashi uku masu zuwa: α Alloy( α+β) Alloy da β Alloy.A kasar Sin, TA, TC da TB sun nuna ta bi da bi.
α titanium
Yana da α Single lokaci gami hada da lokaci m bayani ne α Phase, barga tsarin, mafi girma lalacewa juriya fiye da tsarki titanium, mai karfi hadawan abu da iskar shaka juriya.Ƙarƙashin zafin jiki na 500 ℃ ~ 600 ℃, har yanzu yana kula da ƙarfinsa da juriya mai rarrafe, amma ba za a iya ƙarfafa shi ta hanyar maganin zafi ba, kuma ƙarfin zafin dakinsa ba shi da yawa.
β titanium
Yana da β Alloy na lokaci-lokaci wanda ya ƙunshi ƙwaƙƙwaran lokaci yana da ƙarfi mafi girma ba tare da maganin zafi ba.Bayan quenching da tsufa, haɗin yana ƙara ƙarfafawa, kuma ƙarfin zafin jiki na dakin zai iya kaiwa 1372 ~ 1666 MPa;Duk da haka, kwanciyar hankali na thermal ba shi da kyau kuma bai dace da amfani a yanayin zafi ba.
α+ β titanium
Yana da gawa mai dual lokaci tare da kyawawan kaddarorin haɓaka, kyakkyawan kwanciyar hankali na tsari, mai kyau tauri, filastik da kaddarorin nakasar zafin jiki.Ana iya amfani dashi don sarrafa matsa lamba mai zafi, quenching da tsufa don ƙarfafa gami.Ƙarfin bayan maganin zafi yana kusan 50% ~ 100% mafi girma fiye da haka bayan annealing;Ƙarfin zafin jiki, yana iya aiki a 400 ℃ ~ 500 ℃ na dogon lokaci, kuma kwanciyar hankali ta thermal bai kai α Titanium gami ba.
Daga cikin nau'ikan titanium guda uku α Titanium alloys da α + β Titanium alloy;α Titanium alloy yana da mafi kyawun injina, α+ P Titanium alloy yana ɗaukar wuri na biyu, β Titanium alloy mara kyau.α Code of titanium alloy TA, β Lambar titanium alloy shine TB, α + β Lambar alloy titanium shine TC.
Titanium alloys za a iya raba zuwa ga zafi juriya gami, high-ƙarfi gami, lalata resistant gami (titanium molybdenum, titanium palladium alloys, da dai sauransu), ƙananan zafin jiki gami da na musamman na aiki gami (titanium baƙin ƙarfe hydrogen ajiya kayan da titanium nickel memory alloys). ) bisa ga aikace-aikacen su.
Heat magani: titanium gami iya samun daban-daban lokaci abun da ke ciki da kuma tsarin ta daidaita zafi magani tsari.An yi imani da cewa m microstructure mai kyau yana da kyawawan filastik, kwanciyar hankali na thermal da ƙarfin gajiya;Tsarin acicular yana da ƙarfin fashewar ƙarfi, ƙarfi mai raɗaɗi da taurin karya;Ganyayyaki masu daidaitawa da kyallen takarda suna da ingantattun ayyuka
