Nyob rau hauv Suav teb, lub naming tswvyim ntawm titanium alloy cov ntaub ntawv feem ntau yog sib cais nyob rau hauv peb pawg:
· -type titanium alloys (nrog rau ze li hom alloy) raug xaiv nrog TA
· -type titanium alloys (xws li yuav luag hom alloy) raug xaiv nrog TB
· + - hom titanium alloys raug xaiv nrog TC
①Cov ntsiab lus stabilize theem thiab nce theem hloov pauv kub yog -stable ntsiab, xws li txhuas, carbon, oxygen, thiab nitrogen. Aluminium yog lub ntsiab alloying ntawm titanium alloys, uas muaj kev pom zoo rau kev txhim kho lub zog ntawm titanium alloy nyob rau hauv chav tsev kub thiab kub kub, txo cov kev nqus, thiab nce elastic modulus.
②Cov ntsiab lus uas ruaj khov rau theem thiab txo cov theem hloov pauv kub yog categorized li -stable ntsiab, uas tuaj yeem muab faib ua hom isomorphous thiab eutectoid hom. Cov hom isomorphous muaj molybdenum, niobium, vanadium thiab lwm yam, thaum eutectoid hom muaj xws li chromium, manganese, tooj liab, hlau, silicon, thiab lwm yam.
③Cov ntsiab lus tsis tshua muaj txiaj ntsig ntawm qhov kub ntawm theem hloov pauv yog categorized li nruab nrab alloying ntsiab, xws li zirconium thiab tin.
Cov qib titanium alloy feem ntau piv nrog UNS cov lej raws li hauv qab no

Oxygen, nitrogen, carbon thiab hydrogen yog lub ntsiab impurities hauv titanium alloys. Oxygen thiab nitrogen muaj siab solubility nyob rau hauv theem, uas yuav ntxiv dag zog rau lub titanium alloy ho, tab sis txo lub plasticity. Cov ntsiab lus ntawm oxygen thiab nitrogen hauv titanium feem ntau txhais tau tias tsawg dua {{0}}.15 ~ 0.2% thiab 0.04 ~ 0.05%, feem.
Lub solubility ntawm hydrogen nyob rau hauv theem yog me me, thiab ntau heev hydrogen yaj nyob rau hauv titanium alloys yuav tsim hydride, ua rau cov alloy nkig. Feem ntau, cov ntsiab lus hydrogen hauv titanium alloys yog tswj hauv qab no 0.015%. Lub dissolution ntawm hydrogen nyob rau hauv titanium yog reversible thiab yuav raug tshem tawm los ntawm lub tshuab nqus tsev annealing.

Feem ntau siv titanium alloy muaj pes tsawg leeg yog Ti-6Al-4V, uas raws li Asmeskas tus qauv yog Qib 5 thiab raws li Suav lub npe TC4. Xyoo 1994 National standard GB/T3620.1-2007 tau hloov kho thiab tshem tawm 2 qib titanium thaum ntxiv 54 qib tshiab. Tus lej tshiab ntawm titanium thiab titanium alloy qib yog 76.
Tom qab cov khoom tsim tawm ntawm peb lub "tsib-xyoo-laus cov phiaj xwm", lub cim tshiab ntawm cov pob txha caj qaum titanium alloy khoom nrog Suav tsim cov yam ntxwv tau pib ua kom zoo. Lub zog nruab nrab thiab kev puas tsuaj siab rau titanium alloy TC4-DT ntawm nws tus kheej tsim nyob rau hauv Suav teb muaj tib lub npe muaj pes tsawg leeg li TC4, tab sis cov ntsiab lus ntawm cov pa oxygen yog txo thiab cov pob txha toughness zoo dua.
Cov ntaub ntawv tshiab xws li Ti45NB (cov khoom siv hlau), TA18 (cov khoom siv yeeb nkab), TB8 (cov ntaub ntawv, cov khoom siv hlau, forgings) thiab TC21 (forgings) kuj tau siv zoo. Los ntawm kev sib txuas cov uas twb muaj lawm TC1 / TC2 (GR1 / GR2 phaj), TC4 (GR5) (forgings, daim hlau, xov hlau) thiab ZTC4 cam khwb cia titanium alloy, ua tiav cov khoom uas tsis tshua muaj zog thiab siab plasticity, nruab nrab lub zog thiab siab plasticity. , siab zog thiab siab plasticity, ultra-siab zog titanium alloy thiab cam khwb cia titanium alloy tau tsim.
