U Tseba Hokae ka Ts'ebetso ea Tlhahiso ea Titanium? (tse peli)

Ho tsoa sengoloa se fetileng:

Titanium e entsoe ka libopeho tse nang le thuso, tabeng ea EBCHR, hangata ke ea forging.

E entsoe le ho lahlela titanium

Joale titanium e ka lahleloa kapa ea etsoa hore e hlahise tšepe e nang le thepa e lakatsehang. Ho lahla ho hloka ho futhumatsa tšepe hore e qhibilihe 'me hangata e sebelisetsoa lits'ebetso tse sa hlokahaleng moo litšenyehelo e leng taba e kholo.

Ha titanium e le boemong ba mokelikeli, e tšeloa ka har'a hlobo ho etsa sebopeho se lakatsehang. E bitsa chelete e ka tlase ho titanium e entsoeng 'me e ka theha libopeho tse haufi tsa marang-rang bakeng sa lits'ebetso tse amanang. Mokhoa oa ho lahla o hōlisa li-dendrite—e leng mohaho o kang oa sefate o ka fokolisang tšepe, oa fokotsa tšebeliso ea oona linthong tse itseng.

Forging ke tšebeliso ea matla a mocheso le mochine ho billet ea titanium kapa ingot ho etsa hore thepa e fetohe sebopeho boemong ba eona bo tiileng. Ka lebaka la ts'ebetso ea tšepe le mocheso o phahameng le khatello e amehang, ingot e koahetsoe ka glaze / khalase e sireletsang. Sena se e thibela ho sebetsana le sepakapaka, ha e ntse e lumella ho holofala. The forging process ka ka katleho ntshetsa pele a lakatsa tšepe microstructure.

Phekolo ea Mocheso ea Titanium

Kalafo ea mocheso e lumella ho qhekella ha mekhahlelo ho li-alpha beta alloys. Liphetoho tse ileng tsa fetoha e ne e le sebopeho, boholo le kabo.

Ho kenngoa ha motsoako oa titanium

Annealing ke mokhoa oa ho phekola mocheso oa metallurgic o fetolang lik'hemik'hale le thepa ea 'mele ea titanium. E etsa hore liathomo li falle ka har'a lesela la tšepe, ho fetola thepa ea motsoako. Lintlafatso tsena li kenyelletsa: ductility mocheso o tikolohong, ho tiea ha fracture, khanyetso ea creep le botsitso ba mocheso. Bongata ba thepa ena e ikhethile, kahoo potoloho e khethiloeng e tla bontša ho qetela ho sebelisoa ha tšepe. Ho na le liphekolo tse 'ne tsa mantlha tsa annealing.

Alpha le haufi-alpha li-alloys ha li fetoloe haholo ke lits'ebetso tsena, ho na le monyetla oa ho ba le khatello ea maikutlo le ho fokotsa khatello ea maikutlo. Sena ke hobane ba kena phetohong e fokolang haholo, e ke keng ea hlophisoa bocha ka lebaka la boteng bo fokolang ba mohato oa beta. Phekolo ea tharollo le botsofali li tla eketsa matla a li-alpha alloys.

a. Mill annealing ke mofuta o atileng haholo oa ho kolobisa 'me o hlahisa boholo ba lijo-thollo bo bobebe, bo leng molemo maemong ao matla a chai a leng betere ho feta matla a ho hahaba. Hangata e etsoa e le mohato o ikhethang oa tlhahiso.

b. Dual phase annealing e ntlafatsa creep resistance le fracture toughness ka ho fetola sebopeho, boholo le kabo ea sebaka sa karolo ea tšepe.

c. Recrystallization annealing ke mokhoa o ka ntlafatsang ductility ea tšepe. Lithollo tse holofetseng li nkeloa sebaka ke lithollo tse nang le bokooa. Libaka tsa mantlha tsa beta tse entsoeng qalong li kholo haholo 'me likheo lipakeng tsa tsona li theha mehala e ka bang teng ea bofokoli, e sa lokelang lits'ebetso tse phahameng tsa khatello ea maikutlo. Recrystallization e etsa hore libaka tsena li qhalane, li etse likristale tse nyane, tse sa ts'oanang hantle tse matla.

d. Beta annealing e loketse metastable beta alloys. Hase feela hore ba ka imolla khatello ea maikutlo le ho fokolloa, ba ka boela ba phekoloa le ho tsofala.

Khatello ea kelello e imolla motsoako oa titanium

Ena ke mokhoa o tloaelehileng oa phekolo ea mocheso. E sebelisoa mefuteng e mengata ea li-alloys tsa titanium, ho kenyelletsa le alpha le haufi le alpha alloys le alpha beta le metastable beta alloys. Sepheo ke ho fokotsa khatello ea kelello e setseng e hlahisoang nakong ea ts'ebetso ea tlhahiso.

Phekolo ea Tharollo le Botsofali ba Titanium Alloys

Tharollo annealing, quenching le botsofali hlahisa phahameng ka ho fetisisa matla alloy titanium. Mokhahlelo oa beta oa li-alloys tsa titanium o qala ho bola ka mocheso o ka tlase ho phetoho ea beta, ho o feta ka lialpha tse ling tsa alpha beta ho fokotsa ductility ea tšepe.

Ka mor'a hore alloy e phekoloe mocheso, e ka etsoa lihlahisoa tsa motheo tse ka sebelisoang, ho kenyelletsa lipoleiti, maqephe, li-tubes, mekoallo le lithapo, tse lokiselitsoeng ho sebetsa.
