I-Titanium alloy iyingxubevange eyakhiwe nge-titanium nezinye izakhi. I-Titanium inezinhlobo ezimbili zamakristalu afanayo kanye ne-heterogeneous: isakhiwo esine-hexagonal esondelene ngaphansi kuka-882 ℃ α Titanium, i-cubic emaphakathi yomzimba ngaphezu kuka-882 ℃ β Titanium. Manje ake ozakwethu boMnyango Wezobuchwepheshe we-RSM babelane ngendlela yokukhetha yamapuleti e-titanium alloy
Izidingo zobuchwepheshe:
1. Ukwakheka kwamakhemikhali kwe-titanium alloy plate kuzothobelana nezinhlinzeko ze-GB/T 3620.1, futhi ukuchezuka okuvunyelwe kokwakheka kwamakhemikhali kuzothobelana nezinhlinzeko ze-GB/T 3620.2 lapho i-Demander iphinda ihlola.
2. Iphutha elivumelekile lokujiya kwepuleti lizohambisana nezinhlinzeko eziseThebula I.
3. Iphutha elivumelekile lobubanzi nobude bepuleti lizohambisana nezinhlinzeko kuThebula II.
4. Ikhona ngalinye lepuleti lizosikwa libe yi-angle engakwesokudla ngangokunokwenzeka, futhi ukusika kwe-oblique ngeke kudlule ukuphambuka okuvumelekile kobude nobubanzi bepuleti.
Izakhi ze-alloy zingahlukaniswa ngezigaba ezintathu ngokuya nomthelela wazo ekushiseni koshintsho:
① Isigaba esingu-α esizinzile, izakhi ezikhuphula izinga lokushisa lesigaba yizici ezizinzile zifaka i-aluminium, ikhabhoni, umoya-mpilo ne-nitrogen. I-Aluminium iyisici esiyinhloko sengxubevange ye-titanium alloy, enemiphumela esobala ekuthuthukiseni amandla engxubevange ekamelweni lokushisa kanye nokushisa okuphezulu, ukunciphisa amandla adonsela phansi athile nokwandisa i-elastic modulus.
② Isigaba esingu-β esizinzile, izakhi ezinciphisa izinga lokushisa lokushintsha kwesigaba yizici ezizinzile zingahlukaniswa zibe izinhlobo ezimbili: isomorphic ne-eutectoid. Kusetshenziswa imikhiqizo ye-Titanium alloy. Owokuqala uhlanganisa i-molybdenum, i-niobium, i-vanadium, njll; Lokhu kuhlanganisa i-chromium, i-manganese, ithusi, insimbi, i-silicon, njll.
③ Izakhi ezingathathi hlangothi, njenge-zirconium ne-tin, zinomthelela omncane kuzinga lokushisa lokushintsha kwesigaba.
I-oksijeni, i-nitrogen, i-carbon ne-hydrogen ukungcola okuyinhloko kuma-alloys e-titanium. I-oksijeni ne-nitrogen ku-α Kukhona ukuncibilika okukhulu esigabeni, okunomthelela omkhulu wokuqinisa ku-titanium alloy, kodwa kunciphisa ipulasitiki. Ngokuvamile kushiwo ukuthi okuqukethwe komoyampilo ne-nitrogen ku-titanium kungu-0.15~0.2% no-0.04~0.05% ngokulandelanayo. I-Hydrogen ku-α Ukuncibilika esigabeni kuncane kakhulu, futhi i-hydrogen eningi kakhulu encibilikiswe ku-titanium alloy izokhiqiza i-hydride, okwenza ingxubevange ibe brittle. Ngokuvamile, okuqukethwe kwe-hydrogen ku-titanium alloy kulawulwa ngaphansi kuka-0.015%. Ukuncibilika kwe-hydrogen ku-titanium kuyabuyiseleka emuva futhi kungasuswa nge-vacuum annealing.
