I-Titanium Alloy Steel Plate
Incazelo emfushane:
I-Titanium alloy steel plate iyingxubevange eyakhiwe nge-titanium njengesisekelo nezinye izakhi ezingeziwe.I-Titanium inezinhlobo ezimbili zamakristalu afanayo kanye ne-heterogeneous: isakhiwo esiminyene esiyi-hexagonal ngezansi kuka-882 ℃ α Titanium, i-cubic emaphakathi yomzimba ngaphezu kuka-882 ℃ β Titanium.
Ingxubevange ye-Titanium iyingxubevange eyakhiwe nge-titanium njengesisekelo nezinye izakhi ezingeziwe.I-Titanium inezinhlobo ezimbili zamakristalu afanayo kanye ne-heterogeneous: isakhiwo esiminyene esiyi-hexagonal ngezansi kuka-882 ℃ α Titanium, i-cubic emaphakathi yomzimba ngaphezu kuka-882 ℃ β Titanium.
Izakhi ze-alloy zingahlukaniswa zibe izigaba ezintathu ngokusekelwe kuthonya lazo kuzinga lokushisa lokushintsha kwesigaba:
① Okuzinzile α Ama-elementi akhuphula izinga lokushisa lokushintsha kwesigaba ama-elementi azinzile ahlanganisa i-aluminium, ikhabhoni, umoya-mpilo, ne-nitrogen.I-Aluminium iyingxenye eyinhloko ye-alloying ye-titanium alloy, enomthelela obalulekile ekuthuthukiseni izinga lokushisa legumbi namandla okushisa aphezulu we-alloy, ukunciphisa amandla adonsela phansi athile, nokwandisa i-elastic modulus.
② Okuzinzile β Izakhi ezehlisa izinga lokushisa lokushintsha kwesigaba β Izinto ezizinzile zingahlukaniswa zibe izinhlobo ezimbili: isomorphic ne-eutectoid.Imikhiqizo esebenzisa i-titanium alloy Okokuqala ihlanganisa i-molybdenum, i-niobium, i-vanadium, njll;Lokhu kuhlanganisa i-chromium, i-manganese, ithusi, insimbi, i-silicon, njll.
③ Izakhi ezingathathi hlangothi njenge-zirconium nethini zinomthelela omncane kuzinga lokushisa lokushintsha kwesigaba.Umoya-mpilo, i-nitrogen, ikhabhoni, ne-hydrogen ukungcola okuyinhloko kuma-alloys e-titanium.I-oksijeni ne-nitrogen ku-α Kukhona ukuncibilika okuphezulu esigabeni, okunomthelela omkhulu wokuqinisa kuma-alloys e-titanium, kodwa kunciphisa ipulasitiki.Okuqukethwe komoyampilo ne-nitrogen ku-titanium kuvame ukucaciswa ukuthi kube ngaphansi kuka-0.15~0.2% no-0.04~0.05%, ngokulandelanayo.I-Hydrogen ku-α I-solubility esigabeni iphansi kakhulu, futhi i-hydrogen ngokweqile encibilike kuma-titanium alloys ingakhiqiza ama-hydrides, okwenza i-alloy brittle.Okuqukethwe kwe-hydrogen ku-titanium alloys kuvame ukulawulwa ngaphansi kuka-0.015%.Ukuncibilika kwe-hydrogen ku-titanium kuyabuyiseleka emuva futhi kungasuswa nge-vacuum annealing.
