Kev paub ntawm Titanium ntim

1, Muaj ntshiab Titanium nyob rau hauv qhov kev txiav txim ntawm cov kev sib tw zoo li qub, nws lub ntsiab deformation mechanism yog dab tsi?
Lub ntsiab deformation mechanism yog plam. Raws li cov yas txawv txav tawm, muaj ntau ntawm cov nplais khau txuas ntxiv mus, cov qoob loo thiab cov crystal yog kos thiab sib ntswg yas deformation tshaj qhov txwv, tawg tshwm sim. Thaum nyob rau hauv ib lub xeev nyuaj siab, piv txwv li swb predominates, piv txwv li, npleem tau tshwm sim raws ob pawg ntawm cov dav hlau uas muaj 45 qib los ntawm lub zog tensile. Raws li cov khauj khaum ua tiav, cov kab nrib pleb kis, thiab nws qhov kawg tseem nyob ntawm. Cov nplej ze rau qhov tawg kawg yog rub tawm los ntawm kev tsis txaus ntshai heev, thiab txhua lis piam ib puag ncig los ntawm nws ib puag ncig, uas yog swb.
2, Titanium hauv lub zog zoo li qub zog thiab cov hlab ntsha siab feem ntau siv hlau dab tsi yog qhov sib txawv?
Titanium nyob rau hauv cov yam ntxwv ntawm lub zog zoo li qub thiab cov hlab ntsha siab uas feem ntau siv hlau yog txawv, nws tsis muaj qhov pom tseeb ntawm lub cev tawm los, thiab tsim cov txiaj ntsig pom, acoustic emission phenomena, thermoplasticity, txias creep, pseudo-elasticity thiab cov duab cim xeeb thiab lwm yam kev coj cwj pwm tshwj xeeb.

3, Muaj ntshiab Titanium vim li cas hauv 196 degree c kub kub tseem muaj lub siab tawv? Dab tsi yog qhov cuam tshuam rau nws qhov kub kub tsawg?
Muaj cov titanium lub zog nrog qhov txo ntawm qhov ntsuas kub thiab nce, tab sis cov yas tsis tau txo ntau, thiab muaj kev tsim nyog rau siv raws li cov khoom siv kub tsawg. Titanium muaj cov ntau kub ntawm cov khoom kub siab vim nws qhov tseem ceeb deformation ntawm kev kub kub yog tiam ntawm Twined muaju. Nyob rau hauv tib qib ntawm deformation, nrog rau qhov qis dua ntawm qhov kub, yog li ntawd lub tiam ntawm cov nplej thiab cov naj npawb ntawm cov nplej nce, thaum hloov cov duab ntawm lub ntxaib ntxaib. Nrog rau kev nce qib ntawm deformation, yuav ua rau PolyCrystalline sib sau ua ke ⻓ Ua kom tiav cov nplej, kom ua tiav cov nplej ntawm cov nplej nws tus kheej, thiab tom qab ntawd pib qhov nruab nrab deformation.
Lub ntsiab tseem ceeb cuam tshuam qhov kev ua tau zoo ntawm qhov kub thiab txias ntawm titanium yog cov ntsiab lus ntawm cov ntsiab lus interstitial, cov ntsiab lus tsis sib xws (N, 0, H, C) thiab cov ntsiab lus hlau ntawm kev lag luam ntshiab titanium, zoo dua tiv taus txias embrittlement. Thib ob, kev tsim cov txheej txheem ntawm cov khoom siv titanium kuj muaj kev cuam tshuam rau kev ua haujlwm kub. Ntxiv nrog rau kev tswj tsis zoo ntawm cov txheej txheem cov txheej txheem, cov pa roj impurities cuam tshuam rau kev ua haujlwm, stamping thiab molding ntawm qhov txias deformation ntawm qhov kev ua tau zoo ntawm qhov kub thiab txias kuj tseem cuam tshuam. Thaum qhov txias deformation dhau ib qho kev txwv, nws yuav ua rau qis kub embrittlement.
4, Vim li cas anisotropic titanium cov ntaub ntawv raws li isotropic steel siab lub nkoj tsim cov txheej txheem yuav ua rau cov khib nyiab ntau dua?
Muaj cov ntshiab titanium thiab ib-hom titanium alloy ntawm chav tsev kub rau cov kab ntom ntom ntawm hexagonal siv lead ua, cov hlau lattice muaj qhov tseeb tshwm sim ntawm kev nyiam kev taw qhia, uas ua rau anisotropy ntawm titanium ib leeg siv lead ua. Qhov anisotropy no ntxiv dag zog rau hauv cov txheej txheem dov ntawm titanium, yog li cov dov titanium muaj qhov tseem ceeb anisotropy, yog li titanium siab hlab ntsha muaj qhov zoo dua ob txoj kev ntxiv dag zog, uas yog, titanium nyob rau hauv ob txoj kev nyuaj siab nyob rau hauv qhov kev txiav txim ntawm lub lub zog ntawm lub zog unidirectional ntau dua li qhov kev nce ntxiv hauv ib qho kev ntxhov siab ntawm ob txoj hauv kev yog ntxiv dag zog. Rau spherical titanium siab hlab ntsha, cov nyhuv txhawb zog, theoretical thiab sim tau mus txog 50% thiab 40%, feem. Rau puag ncig yooj yim zoo li titanium siab lub nkoj, thaum lub voj voog thiab phaj dov kev taw qhia sib tshooj, qhov kev ua kom muaj zog ntawm cov theoretical thiab kev sim tus nqi ntawm 42% thiab 3 6%; Thaum lub voj voog thiab phaj dov kev taw qhia perpendicular rau theoretical thiab kev sim tus nqi ntawm 48% thiab 37%, feem. Yog li titanium siab hlab ntsha phab ntsa thickness xam txoj kev raws li GB 150-2011 "siab hlab ntsha" kev, kom haus 20% ~ 40% ntau titanium.
5, vim li cas cov dov titanium tshav kub yeeb nkab nplhaib bearing muaj peev xwm ho siab tshaj qhov kev taw qhia axial?
Vim muaj kev lag luam ntshiab titanium thiab "hom titanium alloy cim ntawm kev nyiam kev coj noj coj ua, ua rau anisotropy ntawm titanium ib leeg siv lead ua. Qhov degree ntawm no anisotropy yog ntxiv txhim kho nrog cov txheej txheem dov. Tshwj xeeb, dov titanium raj feem ntau yog orthogonal. anisotropy, uas yog, axial, circumferential thiab radial feem rau peb anisotropic spindle kev taw qhia; thiab tau dov nyob rau hauv ib qho kev taw qhia, yog li cov degree ntawm anisotropy ntawm dov titanium tshav kub exchanger hlab yog siab tshaj lub phaj Raws li lub titanium raj nyob rau hauv lub axial thiab annular bearing xeem tau, nws lub nplhaib tawm los txwv thiab lub zog txwv. siab tshaj qhov kev taw qhia axial, nyob rau hauv uas cov tawm los txwv qhov sib txawv ntawm 33%, yog li lub dov titanium raj nplhaib bearing muaj peev xwm yog ho. siab tshaj qhov kev taw qhia axial, thiab nyob rau hauv bi-directional kev nyuaj siab ntawm titanium raj nyob rau hauv lub yield zog thiab qhov kawg lub zog tshaj nyob rau hauv lub unidirectional kev nyuaj siab tau nce ho.
