Alloy khoom: qhov tob tsom xam ntawm qhov zoo thiab qhov tsis zoo
Qhia
Titanium alloy yog ib qho alloy uas muaj lwm yam khoom raws li titanium cov ntsiab lus. Titanium muaj ob hom homogeneous crystals: titanium yog ib qho isomer, melting point ntawm 1668 degree, qis dua 882 degree, hu ua -titanium; saum 882 degree, hu ua -titanium. Siv cov yam ntxwv sib txawv ntawm ob lub qauv saum toj no ntawm titanium, cov ntsiab lus alloy tsim nyog tau ntxiv los hloov.
1. Qhov zoo ntawm titanium alloy
1) Lub zog siab: Titanium alloy muaj lub zog siab heev, tab sis qhov ceev yog me me, yog li nws lub zog tensile yog siab dua lwm cov ntaub ntawv hlau, tsim nyog rau kev tsim cov khoom muaj zog, lub teeb yuag.
2) Corrosion kuj: titanium alloy muaj corrosion kuj zoo, tshwj xeeb tshaj yog nyob rau hauv acid thiab alkali ib puag ncig. Qhov no ua rau titanium alloy muaj kev thov dav dav hauv kev lag luam tshuaj, Marine engineering thiab lwm yam haujlwm.
3) Zoo thermal stability: titanium alloy tseem tuaj yeem tswj cov khoom zoo hauv qhov kub thiab txias, yog li titanium alloy kuj yog qhov kev xaiv zoo hauv cov cuab yeej ua haujlwm hauv qhov kub thiab txias.
4) Cov txheej txheem yooj yim: Kev ua haujlwm nyuaj ntawm titanium alloy yog qhov tsawg, yooj yim rau kev tsim thiab vuam, muab cov neeg tsim qauv nrog ntau qhov chaw rau kev tsim.
2. Qhov tsis zoo ntawm titanium alloys
1) Tus nqi siab: Tus nqi npaj ntawm titanium alloy yog qhov siab, yog li nws kuj tseem kim, uas txwv nws daim ntawv thov hauv qee qhov chaw.
2) Qhov nyuaj hauv vuam: lub melting point ntawm titanium alloy yog siab, thiab cov kab nrib pleb thiab cua qhov yog ib qho yooj yim los tsim nyob rau hauv cov txheej txheem vuam, uas ua rau kom qhov nyuaj ntawm vuam.
3) Kev kho cua sov siab: titanium alloy yog ib qho yooj yim los tsim oxidation thiab deformation hauv cov txheej txheem ntawm kev kho cua sov, nrog rau cov kev xav tau siab rau kev siv tshuab.
4) Loj brittleness: Qhov cuam tshuam toughness ntawm titanium alloy tsis zoo nyob rau hauv chav tsev kub, uas yooj yim rau tawg, uas txwv nws daim ntawv thov nyob rau hauv tej yam kev mob.
Xaus
Hauv kev xaus, titanium alloy, raws li cov khoom siv zoo heev, tau siv dav hauv ntau qhov chaw. Txawm li cas los xij, vim yog tus nqi, kev ua haujlwm nyuaj, kev kho cua sov thiab lwm yam kev txwv, peb yuav tsum xaiv seb puas siv titanium alloy raws li qhov xav tau tiag tiag. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm kev siv thev naus laus zis, nws ntseeg tau tias qhov kev ua tau zoo thiab kev siv ntawm titanium alloy yuav raug txhim kho ntxiv.
