Titanium alloy yog ib qho alloy uas muaj titanium thiab lwm yam khoom. Titanium muaj ob hom homogeneous thiab heterogeneous crystals: zoo packed hexagonal qauv hauv qab no 882 ℃ α Titanium, lub cev centered cubic saum 882 ℃ β Titanium. Tam sim no cia cov npoj yaig los ntawm RSM Technology Department los qhia txog txoj kev xaiv ntawm titanium alloy daim hlau
Technical xav tau:
1. Cov tshuaj muaj pes tsawg leeg ntawm titanium alloy phaj yuav tsum ua raws li cov kev cai ntawm GB / T 3620.1, thiab kev tso cai sib txawv ntawm cov tshuaj muaj pes tsawg leeg yuav tsum ua raws li cov kev cai ntawm GB / T 3620.2 thaum Lub Demander rov tshuaj xyuas.
2. Qhov tso cai yuam kev ntawm phaj thickness yuav tsum ua raws li cov kev cai hauv Table I.
3. Qhov kev tso cai yuam kev ntawm phaj dav thiab ntev yuav tsum ua raws li cov kev cai hauv Table II.
4. Txhua lub ces kaum ntawm lub phaj yuav tsum tau txiav mus rau hauv ib lub kaum sab xis kom deb li deb tau, thiab oblique txiav yuav tsum tsis txhob tshaj qhov tso cai sib txawv ntawm qhov ntev thiab dav ntawm lub phaj.
Cov ntsiab lus alloy tuaj yeem muab faib ua peb pawg raws li lawv cov kev cuam tshuam ntawm kev hloov pauv kub:
① Stable α Phase, cov ntsiab lus uas nce qib hloov pauv kub yog α Cov ntsiab lus ruaj khov muaj xws li txhuas, carbon, oxygen thiab nitrogen. Aluminium yog lub ntsiab alloy tseem ceeb ntawm titanium alloy, uas muaj qhov pom tseeb los ntawm kev txhim kho lub zog ntawm cov hlau ntawm chav tsev kub thiab kub, txo qhov tshwj xeeb lub ntiajteb txawj nqus thiab nce elastic modulus.
② Stable β Phase, cov ntsiab lus uas txo cov theem hloov pauv kub yog β Cov ntsiab lus ruaj khov tuaj yeem muab faib ua ob hom: isomorphic thiab eutectoid. Cov khoom siv titanium alloy yog siv. Cov qub muaj xws li molybdenum, niobium, vanadium, thiab lwm yam; Cov tom kawg suav nrog chromium, manganese, tooj liab, hlau, silicon, thiab lwm yam.
③ Cov ntsiab lus nruab nrab, xws li zirconium thiab tin, muaj kev cuam tshuam me ntsis ntawm qhov hloov pauv kub.
Oxygen, nitrogen, carbon thiab hydrogen yog lub ntsiab impurities hauv titanium alloys. Oxygen thiab nitrogen nyob rau hauv α Muaj ib tug loj solubility nyob rau hauv lub theem, uas muaj ib tug tseem ceeb ntxiv dag zog rau ntawm titanium alloy, tab sis txo lub plasticity. Nws feem ntau tau teev tseg tias cov ntsiab lus ntawm oxygen thiab nitrogen hauv titanium yog 0.15 ~ 0.2% thiab 0.04 ~ 0.05% feem. Hydrogen nyob rau hauv α Lub solubility nyob rau hauv lub theem yog heev me me, thiab ntau heev hydrogen yaj nyob rau hauv lub titanium alloy yuav tsim hydride, ua rau cov alloy nkig. Feem ntau, cov ntsiab lus hydrogen hauv titanium alloy yog tswj hauv qab 0.015%. Lub dissolution ntawm hydrogen hauv titanium yog thim rov qab thiab tuaj yeem raug tshem tawm los ntawm lub tshuab nqus tsev annealing.
