Letlapa la tšepe la Titanium Alloy
Tlhaloso e Khutšoanyane:
Titanium alloy steel plate ke motsoako o entsoeng ka titanium joalo ka motheo le likarolo tse ling.Titanium e na le mefuta e 'meli ea likristale tsa homogenous le heterogeneous: sebopeho se teteaneng sa hexagonal ka tlase ho 882 ℃ α Titanium, 'mele o bohareng ba cubic ka holimo ho 882 ℃ β Titanium.

Lintho tsa alloy li ka aroloa ka mekhahlelo e meraro ho latela tšusumetso ea tsona ho mocheso oa phetoho ea mohato:
① E tsitsitseng α Lintho tse eketsang mocheso oa phetoho ea mohato ke α Lintho tse tsitsitseng li kenyelletsa aluminium, carbon, oxygen le nitrogen.Aluminium ke karolo e ka sehloohong ea motsoako oa titanium alloy, e nang le phello e kholo ho ntlafatseng mocheso oa kamore le matla a mocheso o phahameng oa motsoako, ho fokotsa matla a khoheli le ho eketsa modulus ea elastic.
② E tsitsitseng β Lintho tse theolang mocheso oa phetoho ea mohato ke β Lintho tse tsitsitseng li ka aroloa ka mefuta e 'meli: isomorphic le eutectoid.Lihlahisoa tse sebelisang titanium alloy Ea pele e kenyelletsa molybdenum, niobium, vanadium, joalo-joalo;Ea ho qetela e kenyelletsa chromium, manganese, koporo, tšepe, silicon, joalo-joalo.
③ Lintho tse sa nke lehlakore tse kang zirconium le thini li na le phello e fokolang ho mocheso oa phetoho ea mohato.Oksijene, naetrojene, carbon, le hydrogen ke litšila tse ka sehloohong tsa li-alloys tsa titanium.Oksijene le naetrojene ho α Ho na le solubility e phahameng karolong, e nang le phello e matla ea ho matlafatsa li-alloys tsa titanium, empa e fokotsa polasetiki.Likahare tsa oksijene le naetrojene ho titanium hangata li hlalosoa e le ka tlase ho 0.15 ~ 0.2% le 0.04 ~ 0.05%, ka ho latellana.Hydrogen in α The solubility mokhahlelong e tlase haholo, 'me haedrojene e feteletseng e qhibilihisitsoeng ka li-alloys tsa titanium e ka hlahisa li-hydrides, e leng ho etsa hore alloy e brittle.Likahare tsa hydrogen ka har'a li-alloys tsa titanium hangata li laoloa ka tlase ho 0.015%.Ho qhibiliha ha hydrogen ho titanium ho ka khutlisetsoa morao 'me ho ka tlosoa ka vacuum annealing.
