Izakhiwo ze-Titanium Alloy Mechanical
Ukusetshenziswa kwezinga lokushisa ngamakhulu ambalwa degrees ephakeme kune-aluminium ingxubevange, ekushiseni okuphakathi usengakwazi ukugcina amandla adingekayo, kungaba 450 ~ 500 ℃ lokushisa isikhathi eside ukusebenza lezi titanium ingxubevange ezimbili uhla 150 ℃ ~ 500 ℃ isenamandla athile aphezulu kakhulu, futhi ingxubevange ye-aluminium ku-150 ℃ amandla athile ehle kakhulu. Izinga lokushisa lokusebenza le-titanium alloy lingafinyelela ku-500 ℃, futhi ingxube ye-aluminium ingaphansi kuka-200 ℃. Ukumelana nokugqwala okuhle kokugoqa.
Ukumelana nokugqwala kwe-titanium alloy kungcono kakhulu kunokwensimbi engagqwali uma kusebenza emkhathini oswakeme naphakathi namanzi olwandle. Ukumelana okuqinile ikakhulukazi nokugqwala kwe-pitting, ukugqwala kwe-asidi nokugqwala kwengcindezi; Inokumelana nokugqwala okuhle kakhulu kwe-alkali, i-chloride, izinto eziphilayo ezine-chlorine, i-nitric acid, i-sulfuric acid, njll. Nokho, i-titanium inokumelana nokugqwala okungekuhle emithonjeni ye-oksijini enciphisayo ne-chromium kasawoti.
Ingxubevange ye-Titanium ingagcina izakhiwo zayo zokusebenzisa emazingeni okushisa aphansi naphansi kakhulu. Ama-alloys e-Titanium anokusebenza okuhle kwezinga lokushisa eliphansi nezinto eziphansi kakhulu ze-interstitial, njenge-TA7, angagcina ipulasitiki ethile ku- -253℃. Ngakho-ke, i-titanium alloy nayo iyimpahla ebalulekile yesakhiwo sokushisa okuphansi. Umsebenzi wamakhemikhali we-titanium uphakeme, futhi umkhathi ku-O, N, H, CO, CO₂, umhwamuko wamanzi, i-ammonia nokunye ukusabela kwamakhemikhali okunamandla. Uma okuqukethwe kwekhabhoni kungaphezu kuka-0.2%, kuzokwakha i-TiC eqinile ku-titanium alloy;
Emazingeni okushisa aphezulu, ukusebenzisana ne-N kuzophinde kwakha indawo eqinile ye-TiN; Ngaphezu kuka-600 ℃, i-titanium imunca umoya-mpilo ukuze yakhe ungqimba oluqinile olunokuqina okuphezulu; Isendlalelo se-embrittlement sizokwakhiwa lapho okuqukethwe kwe-hydrogen kukhuphuka. Ukujula kwe-hard brittle surface ekhiqizwa igesi emuncayo bungafinyelela ku-0.1 ~ 0.15mm, kanti izinga lokuqina lingama-20% ~ 30%. Ukuhlangana kwamakhemikhali kwe-titanium nakho kukhulu, kulula ukukhiqiza ukunamathela endaweni yokungqubuzana.
I-thermal conductivity ye-titanium λ=15.24W/ (mK) cishe i-1/4 ye-nickel, i-1/5 yensimbi, i-1/14 ye-aluminium, futhi ukuqhutshwa kokushisa kwazo zonke izinhlobo ze-titanium alloy cishe kungaphansi ngo-50% kunalokho. kwe-titanium. I-elastic modulus ye-titanium alloy icishe ibe yi-1/2 yensimbi, ngakho-ke ukuqina kwayo akulungile, kulula ukuguquguquka, akufanele kwenziwe ngentonga emincane nezingxenye ezinodonga oluncane, ukusika ivolumu ye-rebound yokucubungula indawo inkulu, cishe izikhathi ezi-2 ~ 3. yensimbi engagqwali, okuholela ekungqubuzaneni okukhulu, ukunamathela, ukuguga kokubopha ngemuva kwendawo yamathuluzi.
