Titanium Alloy: Lub teeb yuag Alloy khoom nrog kev ua tau zoo heev

Titanium alloy, raws li ib tug alloy raws li titanium thiab tsim los ntawm lwm yam alloying ntsiab, yog dav siv nyob rau hauv ntau lub teb vim nws cov yam ntxwv tshwj xeeb. Titanium alloys tau muab faib ua ntau pawg, suav nrog cov txheej txheem titanium alloys, kub-resistant titanium alloys, thiab -type, -type thiab + -type titanium alloys cais raws li cov qauv siv lead ua.

1.Qhov kev txhim kho keeb kwm ntawm titanium alloys txij li xyoo 1950, titanium alloys tau pib tshwm sim thiab maj mam tsim los ua ib qho tseem ceeb ntawm cov hlau. Tebchaws Asmeskas tau ua tiav thawj zaug titanium alloy, Ti-6Al-4V alloy, hauv xyoo 1954. Nws qhov kev ua tau zoo heev ua rau nws cov khoom lag luam trump hauv kev lag luam titanium alloy. Nrog rau kev nce qib ntawm thev naus laus zis, cov cua sov ua haujlwm, kev tiv thaiv corrosion, lub zog thiab lwm yam khoom ntawm titanium alloys tau raug txhim kho thiab ua kom zoo dua qub.

2. Kev faib tawm tseem ceeb ntawm titanium alloys Kev faib tawm ntawm titanium alloys feem ntau yog nyob ntawm lawv qhov sib txawv ntawm theem hloov pauv kub thiab theem cov ntsiab lus. Nyob rau hauv chav tsev kub, titanium alloys yuav muab faib ua peb pawg: alloys, (+) alloys thiab alloys. Ntawm lawv, titanium alloy muaj cov qauv ruaj khov thiab hnav tsis kam thiab oxidation tsis kam; titanium alloy muaj lub zog siab thiab tsis zoo thermal stability; (+) titanium alloy muaj cov khoom zoo heev, haum rau ntau yam kev kho cua sov.

3. Kev ua tau zoo ntawm titanium alloy

1) Qaub tsawg thiab cov peev xwm loj: Lub ntom ntom ntawm titanium alloys feem ntau tsuas yog 60% ntawm cov hlau, tab sis nws lub zog yog ze rau los yog ntau tshaj ntawm ntau cov alloy hlau. Qhov no ua rau cov titanium alloys yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom sib sib zog nqus, lub zog siab.

2) Lub zog thermal: Kev siv kub ntawm titanium alloy yog siab dua li ntawm aluminium alloy. Nws tuaj yeem tswj tau qhov xav tau lub zog ntawm qhov kub nruab nrab thiab tshwj xeeb tshaj yog haum rau kev ua haujlwm hauv qhov kub thiab txias.

3) Zoo corrosion kuj: Titanium alloy qhia tau hais tias zoo heev corrosion kuj nyob rau hauv cov huab cua thiab seawater media, thiab muaj zoo kuj rau ntau yam corrosive xov xwm.

4) Cov khoom kub tsis zoo: 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 tsis tshua muaj siab tuaj yeem tswj tau qee qib ntawm plasticity ntawm qhov kub thiab txias.

Cov yam ntxwv ua tau zoo ntawm titanium alloys ua rau lawv siv dav hauv aerospace, tshuaj lom neeg kev lag luam, kev kho mob thiab lwm yam haujlwm. Nrog kev nce qib ntawm kev siv thev naus laus zis, kev ua haujlwm ntawm titanium alloys yuav ua kom zoo dua qub thiab txhim kho, thiab nws daim ntawv thov teb yuav dav dua.
