Kev tsim kho thiab kev siv cov khoom siv Advanced Alloy

Ntsiab lus: khoom siv science; Advanced alloy khoom; super alloy; daim ntawv thov teb

Nrog rau kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis thiab kev vam meej ntawm tib neeg lub neej, kev loj hlob sai ntawm cov ntaub ntawv tshawb fawb thiab thev naus laus zis tau dhau los ua ib qho kev txhawb nqa tseem ceeb rau kev sib raug zoo thiab kev lag luam. Advanced alloy cov ntaub ntawv yog ib qho tseem ceeb ntawm cov khoom siv science thiab technology, thiab nws daim ntawv thov teb yog dav heev, nws yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub no.

Kev txhim kho keeb kwm ntawm cov khoom siv alloy siab heev:

Advanced alloy cov ntaub ntawv xa mus rau cov ntaub ntawv hlau nrog lub zog siab, siab-kub stability, thiab siab corrosion kuj. Nws txoj kev loj hlob tuaj yeem taug qab mus rau thaum ntxov xyoo pua 20th thaum cov kws tshawb fawb hauv tebchaws United Kingdom thiab Tebchaws Meskas tau pib ua haujlwm ntawm superalloy, uas yog, npib tsib xee-based alloy uas muaj cov ntsiab lus alloying xws li chromium thiab molybdenum. Cov khoom siv hlau no muaj oxidation zoo heev nyob rau hauv lub thermal oxidation ib puag ncig, yog li nws yog dav siv nyob rau hauv aviation, roj av, tshuaj, thiab lwm yam high-temperature teb.

Thaum pib ntawm lub xyoo pua 21st, cov ntaub ntawv alloy siab heev tau ntsib kev hloov kho thiab hloov kho dua tshiab. Cov ntaub ntawv tshiab tshaj plaws alloy siv qee cov ntsiab lus tshiab thiab cov txheej txheem kev npaj ua kom lawv cov khoom zoo tshaj plaws. Piv txwv li, cov khoom siv tungsten alloy tshiab, nws cov macro thiab microstructure yog qhov sib xws, muaj kev tiv thaiv corrosion zoo dua, thiab tuaj yeem ua tau raws li qhov xav tau ntawm aerospace, missiles, thiab lwm yam high-tech fields.

Advanced alloy cov ntaub ntawv muaj ntau yam kev siv hauv kev tsim khoom:

1. Aerospace: Aerospace yog daim ntawv thov tseem ceeb ntawm cov ntaub ntawv alloy siab heev. Advanced alloy cov ntaub ntawv tuaj yeem tiv taus qhov kub thiab txias ib puag ncig, txhim kho kev ua haujlwm ntawm aerospace xyaw thiab turbine xyaw, thiab txo qhov hnyav ntawm cov khoom siv.

2. Petroleum thiab chemicals: Petroleum thiab chemical production yog lwm qhov tseem ceeb. High-temperature, high-pressure roj av thiab cov khoom siv tshuaj yuav tsum tau siv cov ntaub ntawv alloy siab heev los tiv thaiv corrosion thiab high-temperature gas erosion, ua rau cov khoom siv lub neej ntev, thiab txo tus nqi ntawm kev tu thiab hloov.

3. Kev kho mob: Advanced alloy cov ntaub ntawv kuj tseem siv rau hauv kev tsim khoom siv kho mob. Piv txwv li, titanium alloy cov ntaub ntawv tuaj yeem siv los ua cov khoom siv pob txha thiab cov hniav cog, muaj kev tiv thaiv corrosion, thiab zoo bio-compatibility, thiab tib neeg cov ntaub so ntswg yog yooj yim rau fuse.

Nyob rau hauv luv luv, daim ntawv thov teb ntawm advanced alloy cov ntaub ntawv yog ntau thiab ntau, thiab daim ntawv thov ntawm cov khoom yog tas li txhawb thiab txhim kho, ua ib qho tseem ceeb kev txhawb nqa rau niaj hnub industrial ntau lawm.

Cov tshooj tom ntej no yuav tsom mus rau kev siv cov alloys hauv thaj teb ntawmcov ntaub ntawv sciencethiabpetrochemical kev lag luam.
