Qhov zoo ntawm Titanium

Titanium alloy muaj qhov zoo hauv qab no piv nrog lwm cov ntaub ntawv hlau.
① tshaj lub zog (lub zog tensile / ntom) siab (saib daim duab), tensile zog txog li 100 ~ 140kgf / mm2, thaum qhov ceev ntawm tsuas yog 60% ntawm cov hlau.
② lub zog zoo ntawm qhov kub nruab nrab, kev siv qhov kub thiab txias tshaj li cov aluminium alloy ob peb puas degrees siab dua, nyob rau hauv nruab nrab ntawm qhov kub thiab txias tseem tuaj yeem tswj tau qhov yuav tsum tau muaj zog, tuaj yeem ua haujlwm hauv qhov kub ntawm 450 ~ 500 degree mus sij hawm ntev.
③ zoo corrosion kuj, nyob rau hauv cov huab cua, titanium nto tam sim ntawd tsim ib tug uniform ntom oxide zaj duab xis, muaj peev xwm tiv taus ntau yam xov xwm yaig. Feem ntau titanium muaj corrosion kuj zoo nyob rau hauv oxidizing thiab nruab nrab media, thiab corrosion kuj nyob rau hauv seawater, ntub chlorine thiab chloride tov yog zoo heev. Tab sis hauv kev txo cov xov xwm, xws li hydrochloric acid thiab lwm yam kev daws teeb meem, titanium corrosion kuj tsis zoo.
④ kev ua tau zoo ntawm qhov kub thiab txias, qhov sib txawv yog qhov tsawg heev titanium alloy, xws li TA7, hauv -253 degree tuaj yeem tswj tau qee qhov qib ntawm plasticity.
⑤ Tsawg modulus ntawm elasticity, me me thermal conductivity, tsis muaj ferromagnetism.
6. Siab hardness.
7. Tsis zoo stamping, zoo thermoplasticity.
Kev kho cua sov Titanium alloys tuaj yeem tau txais cov txheej txheem sib txawv thiab cov koom haum los ntawm kev kho cov txheej txheem kho cua sov. Nws feem ntau ntseeg tias lub koom haum zoo isometric muaj cov yas zoo dua, thermal stability thiab qaug zog; koob zoo li lub koom haum muaj siab endurance zog, creep zog thiab puas toughness; isometric thiab koob zoo li lub koom haum sib xyaw ua ke muaj kev ua tau zoo tag nrho.

Feem ntau siv cov kev kho cua sov yog annealing, kev daws thiab kev laus kev kho mob. Annealing yog tshem tawm cov kev ntxhov siab sab hauv, txhim kho plasticity thiab kev ruaj ntseg ntawm lub koom haum, txhawm rau kom tau txais kev ua tau zoo tag nrho. Feem ntau alloy thiab (+ ) alloy annealing kub xaiv nyob rau hauv (+ ) - → theem hloov taw tes hauv qab no 120 ~ 200 degree; kev daws teeb meem thiab kev laus kev kho mob yog los ntawm qhov kub thiab txias ntawm cheeb tsam ceev ceev, thiaj li yuav tau txais lub martensite 'theem thiab sub-stabilized theem, thiab tom qab ntawd nyob rau hauv nruab nrab-kub cheeb tsam rwb thaiv tsev kom cov sub-stabilized theem decomposition, tau lub theem lossis cov tebchaw thiab lwm yam me me diffuse theem thib ob ntawm qhov taw tes, kom ua tiav lub hom phiaj ntawm kev ntxiv dag zog rau cov hlau. Lub hom phiaj ntawm kev ntxiv dag zog rau cov hlau. Feem ntau, quenching ntawm (+ ) alloy yog nqa tawm ntawm 40-100 degree hauv qab ntawm (+ )-→ theem hloov chaw, thiab quenching ntawm substable alloy yog nqa tawm ntawm 40-80 degree saum toj no ( + ) - → theem hloov chaw. Kev laus kev kho mob kub yog feem ntau 450-550 degree . Tsis tas li ntawd, txhawm rau ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov khoom ua haujlwm, kev lag luam kuj tseem siv ob chav annealing, isothermal annealing, kev kho cua sov, kev kho cua sov deformation thiab lwm yam txheej txheem kev kho cua sov.
