Indlela yokukhetha ye-titanium alloy plate

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.
