Titanium alloys: hnav alloys nrog cov khoom zoo heev

Titanium alloys, raws li ib yam ntawm cov alloys muaj li ntawm titanium raws li lub hauv paus ntsiab lus thiab los ntawm kev sib ntxiv ntawm lwm yam alloying ntsiab, yog lug siv nyob rau hauv ntau yam teb vim lawv cov yam ntxwv tshwj xeeb. Titanium alloys yog categorized nyob rau hauv ntau txoj kev, nrog rau cov qauv titanium alloys, tshav kub-resistant titanium alloys, thiab -type, -type, thiab + - hom titanium alloys raws li cov qauv siv lead ua.
I. Kev txhim kho keeb kwm ntawm titanium alloy
Txij li thaum xyoo 1950, titanium alloy pib tshwm sim thiab maj mam tsim mus rau hauv cov qauv hlau tseem ceeb. Tebchaws Asmeskas tau ua tiav thawj qhov kev siv titanium alloy - Ti-6Al-4V alloy hauv xyoo 1954, thiab nws qhov kev ua tau zoo tau ua rau nws cov khoom lag luam kingpin hauv kev lag luam titanium alloy. Nrog rau kev nce qib ntawm kev siv tshuab, cov cua kub tsis kam, corrosion kuj, lub zog thiab lwm yam khoom ntawm titanium alloys tau raug txhim kho thiab ua kom zoo dua qub.

Thib ob, lub ntsiab kev faib tawm ntawm titanium alloy
Kev faib tawm ntawm titanium alloy feem ntau yog raws li nws cov theem hloov pauv kub thiab cov ntsiab lus sib txawv. Nyob rau hauv chav tsev kub, titanium alloys yuav muab faib ua peb pawg: alloys, (+) alloys thiab alloys. Ntawm lawv, titanium alloy muaj lub koom haum ruaj khov thiab hnav tsis kam thiab oxidation tsis kam; titanium alloy muaj lub zog siab thiab tsis zoo thermal stability; (+) titanium alloy muaj kev ua tau zoo heev thiab tsim nyog rau ntau yam kev kho cua sov.
Thib peb, cov yam ntxwv ua haujlwm ntawm titanium alloy
1. Tsawg ntom ntom, lub zog muaj zog: lub ntom ntawm titanium alloy feem ntau tsuas yog 60% ntawm cov hlau, tab sis nws lub zog yog ze rau los yog ntau tshaj li ntau cov alloy hlau. Qhov no ua rau titanium alloy dhau los ua cov khoom siv zoo tshaj plaws rau kev tsim khoom hnyav thiab siab zog.
2. Lub zog thermal: kev siv kub ntawm titanium alloy yog ntau dua li ntawm aluminium alloy, thiab nws muaj peev xwm tswj tau lub zog yuav tsum tau nyob rau hauv nruab nrab kub, uas yog tshwj xeeb tshaj yog haum rau kev ua hauj lwm nyob rau hauv high-temperature ib puag ncig.
3. Zoo corrosion kuj: titanium alloy qhia tau hais tias zoo heev corrosion kuj nyob rau hauv cov huab cua thiab seawater nruab nrab, thiab muaj zoo kuj mus rau ntau yam corrosive nruab nrab.
4. Kev ua tau zoo ntawm qhov kub thiab txias: titanium alloys tseem tuaj yeem tswj hwm lawv cov khoom siv hluav taws xob ntawm qhov kub thiab txias, thiab titanium alloys nrog cov ntsiab lus qis heev tseem tuaj yeem tswj tau qee qhov ntawm plasticity ntawm qhov kub thiab txias.
Cov yam ntxwv ua tau zoo ntawm titanium alloy ua rau nws siv dav hauv aerospace, tshuaj, kho mob thiab lwm yam haujlwm. Nrog rau kev nce qib ntawm kev siv thev naus laus zis, kev ua haujlwm ntawm titanium alloy yuav ua tau zoo dua thiab txhim kho, thiab nws daim ntawv thov teb yuav dav dua.
